Carbon monoxide gas detector – reliable safety and control

The DG-22.EN/M gas detector is an economical, digital device designed for continuous monitoring of carbon monoxide concentration in premises. Its task is to provide a quick warning in the event of exceeding permissible norms, which is crucial for the safety of people in a given area and protection of installations. The detector uses a semiconductor sensor, which is characterized by high selectivity and measurement accuracy even at low CO concentrations.

Construction and communication

The device has a splash-proof housing (IP44), which increases its resistance to environmental conditions. Communication is via the RS-485 interface with the MODBUS RTU protocol, enabling integration with supervision and control systems. This allows for remote monitoring of the detector status and quick response to alarms. The replaceable sensor module simplifies maintenance, calibration and reduces operating costs.

Application and benefits

The DG-22.EN/M detector finds wide application in various facilities, such as:

• Industry: production plants, logistics centers, where there is a risk of carbon monoxide emissions.
• Construction: underground garages, parking lots – ventilation control and warning of CO presence.
• Public utility facilities: hotels, offices, schools – ensuring safe conditions for users.
• Heating installations: boiler rooms, furnaces – monitoring the efficiency of devices and detecting leaks.

Thanks to the use of the DG-22.EN/M detector, you gain:

• Early warning: quick reaction to increased carbon monoxide concentration minimizes the risk of poisoning.
• Reliability: built-in microprocessor ensures stable operation and measurement accuracy.
• Ease of use: replaceable sensor module design simplifies maintenance and calibration.
• Integration with systems: the ability to connect to supervision and control systems provides full control over the safety status.
• High quality: all detectors are calibrated in their own GAZEX Calibrating Laboratory accredited in accordance with the PN-EN ISO/IEC 17025 standard (PCA No. AP150).

Technical specifications

The DG-22.EN/M detector offers three alarm thresholds for carbon monoxide (30 ppm, 60 ppm, 150 ppm), allowing you to adjust the sensitivity to specific working conditions. The power supply is 24 V DC. The device also has a function of alarm status history, which facilitates analysis of the causes of failures and optimization of the gas detection system. Additionally, the ability to configure settings using the dedicated "DETnet View" software allows for full personalization of the detector's operation according to individual user needs.
