Gas detection since 1983, wireless gas detection since 2005

The Otis Instruments, Inc. Model OI-617 H2S Sensor Assembly is proven to provide reliable monitoring of Hydrogen Sulfide gas in harsh conditions by using the Otis OI-240 solid state sensor.

The OI-617 H2S Sensor Assembly's key feature is non-intrusive calibration. With all adjustments made at the sensor assembly, one-man non-intrusive calibration is quick, easy, and allows the device to remain Class I, Division 1, Groups C and D certified while in the field. Non-intrusive calibration is made possible by using an Otis Instruments, Inc. distributed magnet to activate the MENU, ADD and SUB buttons. The OI-617 H2S Sensor Assembly is field-adjustable and housed in the Moore explosion and weather proof cast-aluminum housing.

An extended life-expectancy, paired with the ability to withstand extreme climatic conditions and harsh environments, make the OI-617 H2S Sensor Assembly a flexible and dependable safety tool for gas detection.
