Electrochemical Sensor Assembly
Explosion Proof with Display

The OI-675 is an ambient air fixed point remote gas sensor assembly with a two-wire loop-power sensor assembly that uses any any "4" Series electrochemical sensor element to detect a variety of toxic gases including O2, H2S, SO2, CO, NH2, Cl2 and HF.

The OI-675 comes standard with a display with three-button interface, non-intrusive magnetic switches and the Otis-blue custom explosion-proof enclosure.  

   2-wire loop powered
    3-button non-intrusive calibration with MENU, ADD and SUB
   4-20mA analog output
   Explosion and weather proof Otis-Blue enclosure
    Electrochemical sensor elements for gas detection
   Quickly setup and install a remote sensor assembly
   Rapid response and clearing time
