Nitrogen dioxide detector E2630-NO2 is an easy-to-use instrument intended for underground parkings, boiler houses, laboratories, industrial premises and other confined spaces, where potentially toxic concentration of nitrogen dioxide can accumulate.
Default alarm set-points are typically at 3 ppm and at 6 ppm NO2 (release at 2 ppm).
Two relays with switch-over contact may be used for remote signalling or ventilation control. Also the flashing LED and an internal buzzer gives alarms at two set-points.
The instrument utilises novel fully calibrated and temperature compensated electrochemical gas sensor with excellent repeatability, stability and long lifetime.
