Description
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.
The instrument utilises a fully calibrated and temperature compensated electrochemical gas sensor with excellent repeatability, stability and long lifetime.
Two relays with switch-over contact may be used for remote signalling or ventilation control. Flashing LED and internal buzzer give visual and sound alarms.
