Additional information

The NS2 ATEX gas detector allows the monitoring of a wide range of gas concentrations. The device has a range of 88 sensors for different toxic gases, refrigerants, explosives, and volatile organic compounds. Detector sensors are available in various technologies (catalytic, electrochemical, infrared, semiconductor and PID) for different measurement ranges.

With an analog and a digital output as standard, the NS2 gas detector can be configured via PC or magnet (non-intrusive setting). It can be used as a stand-alone detector thanks to its various options (3-relay card and internal buzzer of 88 dBA) or connected to a conventional 4-20 mA gas detection system.
