Gas detector WG-20.EG/A24Nstd CO+NO2, calibration on request, electrochemical + semiconductor sensor, 24V power supply WG-20.EG/A24 NSTD

Gas detector – reliable air quality control

This advanced gas detector is designed for continuous monitoring of carbon monoxide (CO) and nitrogen dioxide (NO2) concentrations in enclosed spaces. The device is used in garages, underground car parks, vehicle inspection stations, car workshops, warehouses and logistics centers – anywhere where air quality control and safety are essential. The detector signals exceeding the permissible gas concentration limits by activating optical signaling and control outputs, allowing automatic activation of ventilation or alarm systems.

Functionality and construction

The WG-20.EG/A24Nstd detector uses electrochemical gas sensors, providing precise and reliable measurement of CO and NO2 concentrations. The built-in microprocessor is responsible for stable operation of the device, thermal compensation and event history. The replaceable gas sensor facilitates maintenance and reduces operating costs. The detector's design is designed for easy installation and operation – all terminals are removable, and the housing (IP54) is splash-proof. The device powered by 24V DC is ready to operate immediately after connection.

Advantages for installers and users

• Versatility: ability to monitor both carbon monoxide and nitrogen dioxide in one device.
• Automation: fully automatic operation of the detector eliminates the need for manual calibration or adjustment.
• Configurability: three programmable alarm thresholds for CO (compliant with PN-EN 50545-1:2012) and three control outputs with the possibility of configuring the common contact connection.
• Reliability: built-in microprocessor ensures stable operation and measurement accuracy.
• Easy sensor replacement: quick and easy sensor replacement minimizes downtime and service costs.
• Calibration: Detectors are factory calibrated in the accredited GAZEX laboratory (PCA No. AP150), which guarantees measurement accuracy from the beginning of use.
• Solid construction: Splash-proof IP54 housing provides protection against moisture and mechanical damage.
• Alarm signaling: Built-in optical signaling informs about exceeding the permissible gas concentration limits.
• Expandability: Additional outputs allow connection of external signaling devices or integration with ventilation systems.
