Description
Volatile Organic Compounds transmitter E2618-VOC is a member of new PluraSens® family of multifunctional measurement instruments which is intended for detection of various solvent vapors, e.g. toluene, xylene, ethanol.
Applications include 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...1000 ppm).
Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the transmitter to safety or building automation systems.
