What Is the ATEX HORA 130 Breathing Air Monitoring Unit?

The ATEX HORA 130 is a portable breathing-air quality monitoring system that continuously analyses compressed air before or while workers use it through supplied-air respiratory equipment.

Many industrial jobs take place in environments where workers cannot safely breathe the surrounding air. Therefore, facilities use compressed breathing-air networks to supply clean air to respirators, masks, hoods, and other breathing equipment.

The HORA 130 continuously checks the quality of that air instead of relying only on occasional manual tests. It measures several important contaminants and operating conditions at the same time, helping safety teams identify changes in air quality quickly.

Key Features of the Explosion Proof Air Quality Monitor

The Explosion Proof Air Quality Monitor combines multi-parameter measurement, continuous supervision, data recording, and remote alarm functionality in a portable industrial unit.

• Continuous carbon monoxide monitoring: The analyser measures CO concentration continuously, helping detect contamination from combustion sources or compressor-air intake problems.
• Continuous carbon dioxide measurement: The HORA 130 tracks CO₂ levels to help identify deteriorating air quality or contaminated compressor intake air.
• Continuous oxygen monitoring: The unit measures O₂ concentration so operators can confirm that breathing air remains within the required oxygen range.
• Humidity and pressure-dew-point measurement: Continuous moisture monitoring helps identify excess water vapour, condensation risk, and poor compressed-air treatment.
• Oil vapour and VOC monitoring: The system checks for oil-related contamination and volatile organic compounds that may enter breathing air from compressors or industrial surroundings.
• Integrated SD card recording: The unit stores measurements for traceability, project documentation, quality records, and later review.
• Continuous sample-flow supervision: The monitor checks air movement through its measuring cells so a blocked or interrupted sample line does not go unnoticed.
• Electrical and pneumatic alarm outputs: The analyser can activate compatible remote warning systems when measurements exceed configured limits or the monitoring system detects a fault.

How Does an Ex Proof Air Quality Monitor Work?

The Ex Proof Air Quality Monitor takes a controlled sample from the compressed breathing-air network and passes it through dedicated sensing cells.

A typical monitoring process works as follows:

1. Compressed breathing air enters the monitoring unit.
2. Internal pneumatic controls condition the sample for analysis.
3. The air passes through the measurement cells.
4. Individual sensors measure CO, CO₂, O₂, humidity, oil vapours, and VOC contamination.
5. The display shows the measured values continuously.
6. The system compares every reading with the configured alarm thresholds.
7. Measurement records are stored on the integrated SD card.
8. Electrical or pneumatic outputs activate remote alarms when the system detects an unsafe condition.

This continuous process allows operators to monitor breathing-air quality throughout an entire work period.

Continuous Carbon Monoxide Monitoring

Carbon monoxide represents one of the most important contaminants in compressed breathing air.

Workers cannot reliably detect CO through smell, taste, or appearance. Therefore, continuous electronic measurement gives safety teams a much more reliable warning method.

CO can enter a compressed-air system through:

• Compressor intake air contaminated by vehicle exhaust.
• Nearby generators.
• Combustion equipment.
• Boilers.
• Industrial engines.
• Poor compressor placement.

The HORA 130 continuously checks CO concentration and allows the alarm system to react if the level rises above the configured limit.

Carbon Dioxide Monitoring

The unit also measures carbon dioxide continuously.

Higher CO₂ concentrations can indicate:

• Contaminated compressor intake air.
• Recirculated exhaust.
• Poor ventilation around the compressor.
• Process-air contamination.
• Abnormal breathing-air treatment conditions.

Continuous monitoring gives operators a clearer picture of changing air quality than periodic spot testing alone.

Oxygen Concentration Monitoring

The HORA 130 continuously measures oxygen concentration in the breathing-air supply.

Correct oxygen content matters because both low and abnormal oxygen levels can indicate problems within the air supply.

Continuous O₂ measurement helps detect:

• Oxygen deficiency.
• Incorrect gas mixing.
• Supply contamination.
• Abnormal compressor intake conditions.
• Problems within air-treatment equipment.

Humidity and Dew Point Monitoring

Moisture can create several problems inside compressed breathing-air systems.

Therefore, the HORA 130 continuously monitors humidity and pressure dew point.

This helps control:

• Condensation.
• Water accumulation.
• Pipeline corrosion.
• Freezing in cold sections.
• Moisture carryover into respiratory equipment.

The system also uses an automatic humidity alarm function that adjusts the alarm threshold according to temperature.

Oil Vapour Monitoring

Compressed-air systems can introduce oil contamination if compressor lubrication, separation, or filtration does not perform correctly.

The HORA 130 continuously monitors oil-related contamination so operators can identify:

• Compressor oil carryover.
• Filter saturation.
• Poor air treatment.
• Contaminated breathing-air lines.
• Hydrocarbon contamination.

This becomes especially important during long industrial jobs where breathing-air quality must remain consistent throughout the work period.

VOC Monitoring

The unit also monitors volatile organic compounds.

VOC contamination may come from:

• Solvents.
• Paints.
• Industrial chemicals.
• Hydrocarbon vapours.
• Cleaning agents.
• Process emissions.
• Compressor intake contamination.

VOC monitoring makes the HORA 130 particularly useful during painting, coating, chemical handling, remediation, decontamination, and industrial maintenance work.

EN 12021 Breathing Air Monitoring

The HORA 130 supports monitoring of compressed breathing air according to EN 12021 requirements.

This standard addresses the quality of compressed gases supplied to respiratory protective equipment.

Important breathing-air parameters include:

Monitoring these parameters helps maintain a suitable breathing-air supply during industrial operations.

Continuous Measurement Display

The unit provides a continuous monochrome display of measured values.

Operators can quickly review:

• CO concentration.
• CO₂ concentration.
• O₂ concentration.
• Humidity.
• Oil/VOC measurement.
• Alarm condition.
• System status.

A local display allows technicians to monitor breathing-air quality directly at the worksite.

Adjustable Alarm Thresholds

The HORA 130 allows operators to configure alarm thresholds according to the required breathing-air standard and worksite procedure.

Once configured, the unit continuously compares current measurements with those limits.

If any reading exceeds the permitted range, the monitoring system can generate a warning.

Automatic Humidity Alarm

The HORA 130 uses an automatic humidity alarm function that adjusts according to temperature.

This feature helps account for the relationship between:

• Temperature.
• Water vapour.
• Dew point.
• Condensation.
• Freezing risk.

It provides more useful moisture supervision than a simple fixed humidity alarm.

Measuring-Cell Flow Supervision

Accurate gas analysis requires a stable sample flow through the sensing cells.

The HORA 130 continuously checks this flow.

Flow monitoring can identify:

• Blocked tubing.
• Restricted sample lines.
• Insufficient air supply.
• Pneumatic failure.
• Interrupted measurement flow.

This additional supervision helps ensure that valid air samples continue reaching the sensors.

Watchdog Fault Monitoring

The unit includes a watchdog function that monitors system faults and alarms.

The watchdog helps identify conditions such as:

• Sensor malfunction.
• Sample-flow failure.
• Communication problems.
• Power interruption.
• Measurement-system faults.

This prevents a monitoring failure from appearing as a normal safe condition.

Positive Fault Security

The HORA 130 supports a positive fault-security approach.

When the system detects a problem, it generates a warning instead of silently continuing operation.

This becomes particularly important in breathing-air applications where personnel rely on the monitoring unit for respiratory safety.

SD Card Data Logging

The integrated SD card stores breathing-air measurements.

Recorded data can support:

• Safety documentation.
• Project records.
• Inspection history.
• Quality verification.
• Alarm investigation.
• Maintenance planning.

Data logging also helps companies maintain proof that they continuously monitored breathing-air quality during critical work.

Communication Port

The analyser includes a communication port for measurement retrieval.

Users can transfer stored monitoring information for:

• Reports.
• Safety records.
• Maintenance analysis.
• Compliance documentation.
• Project handover files.

Electrical Alarm Output

The HORA 130 includes an electrical alarm output for compatible remote warning devices.

A typical arrangement can include:

Breathing Air Supply → HORA 130 → Remote Alarm → Workers

This allows the monitoring unit to warn personnel even when the analyser itself sits away from the actual work location.

Pneumatic Remote Alarm

The unit also supports pneumatic alarm control.

A pneumatic alarm arrangement can provide a robust warning in industrial worksites where personnel use compressed-air respiratory systems.

It can support:

• Pneumatic horns.
• Remote warning systems.
• Alarm panels.
• Worksite safety equipment.

Remote Alarm Functions

A connected remote alarm system can warn operators about several conditions.

These may include:

• Low breathing-air pressure.
• High contaminant concentration.
• Sensor fault.
• Loss of flow.
• Communication failure.
• Electrical power failure.
• Pneumatic supply failure.
• Monitoring-system fault.

This gives workers several layers of warning if air quality or monitoring performance changes.

Alarm During Power Failure

A breathing-air monitoring system must also warn operators if monitoring itself stops.

The HORA 130 supports alarm functions associated with power failure, helping prevent workers from assuming that breathing-air conditions remain normal after monitoring power is lost.

Low Sample Flow

The HORA 130 uses an analysis flow of approximately 30 litres per hour.

This relatively low consumption allows continuous monitoring without drawing excessive air from the respiratory-air network.

2 to 10 Bar Air Pressure Range

This arrangement helps simplify:

• Preventive maintenance.
• Sensor servicing.
• Component replacement.
• Workshop inspection.
• Calibration work.

Sensor Calibration from the Display

Technicians can perform sensor calibration through the local display interface.

This makes routine calibration straightforward and keeps servicing centralised through the analyser’s own controls.

Automatic Oxygen Sensor Calibration

An automatic O₂ calibration option is available.

This can simplify periodic maintenance and improve consistency during repeated monitoring operations.
