OI-6900 Explosion Proof Dual Battery Powered WireFree Sensor Assembly

 

The Otis Instruments WireFree OI-6900 Series Ambient Air Hazardous Gas Detector is a wireless, dual battery-powered assembly that uses an electrochemical or low-power infrared sensor element to detect a variety of toxic or combustible gases. The OI-6900 offers nonintrusive calibration, allowing the device to remain Class I, Division 1, Groups C and D certified, while adjustments are made in the field. The OI-6900 continuously monitors the gas level of the surrounding environment and reports once a minute, the reporting rate will increase to once every five seconds when the detected gas is above the Background Gas Set-point. This set-point is adjustable to account for sites that may have a constant low level of gas always present. The display screen always shows the present gas concentration.

Part Number Formula: OI-6900-[Gas]-[Radio]-O-2B
