Gas Concentration Detection Sensor Evikon E2638-R-NH3-LCD

The gas concentration detection sensor (gas detector) is used for detecting and providing early warning of dangerous (explosive or toxic) concentrations of the detected gas. The sensor is suitable for use in industrial spaces, refrigeration equipment, poultry farms, and other enclosed areas where there is a possibility of dangerous gas accumulation. The detector is equipped with a two-stage alarm system – visual (LCD display) and audible (85db). Additionally, two output relays (voltage-free) with a switching contact can be used for remote signaling or controlling ventilation/EM valve, etc. The sensor is built on the unified PluraSens platform. The platform allows the detector to connect, besides switching relays, also with two analog outputs 0-10V / 4-20mA and a digital ModBus RS485 interface.
Manufactured in a robust design with IP65 protection - ABS plastic, resistant to mechanical damage. Rigid, tough, resistant to low and high temperatures, low absorbency, non-toxic.

The sensor's lifespan is more than 10 years.

The default alarm values are set at 25ppm and 100ppm NH₃. When ordering, it is necessary to specify the application for the correct choice of sensor type. The recommended coverage area for one sensor is 80-120 m², 5-6m radius.

Each sensor is factory-calibrated to default values. The law requires recalibration at least once every 12 months. Calibration can only be performed by a person certified by the manufacturer.
