Description
Solvent vapor detector E2630-VOC is an easy-to-use instrument intended for solvent storages, painting chambers and other confined spaces, where toxic or potentially explosive concentration of volatile organic compounds can accumulate.
The instrument utilises a fully calibrated metal-oxide semiconductor gas sensor with excellent repeatability, stability and long lifetime.
According to user's preferences the detector can be ordered for either fire prevention (range 0...100% LEL) or for toxicity prevention (range 0...500 ppm).
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.
