SEC - Model 3000 Series -Gas Detector

Compact low cost design. Hundreds of reliable, accurate gas sensors are available.   “Gas Free” electrochemical toxic gas sensor calibration.  To switch gas sensors in this gas detection equipment there is no set-up time, no reprogramming and no recalibration.  With an optional IS barrier, this gas detection equipment can be changed without cutting system power.  The SEC 3000 toxic gas detector can be used as a stand alone gas detector with 4-20mA output or it can be used in conjunction with the SEC 3100 explosion proof transmitter, SEC 3120 Dual Transmitter or the SEC 3100 DIN Controller.
