Solvent vapor detector E2630VOC is an easytouse 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 metaloxide semiconductor gas sensor with excellent repeatability, ...
· When the sensor tip is in air, the infrared light inside the sensor tip is reflected back to the detector. When in liquid, the infrared liquid is refracted out of the sensor tip, causing less energy to reach the detector. Being a solidstate device, these compact switches are ideal for a vast range of point level sensing applications, especially when reliability is essential. Optical liquid ...
