Otis Instruments Wireless OI-6940, AC-Powered Ambient Air Multi-Gas Detector

Otis Instruments OI-6940-X-X-NXP Quad Sensor Assembly

The Otis Instruments Wireless OI-6940 Non-Explosion Proof AC-Powered Ambient Air Multi-Gas Detector simultaneously uses up to four sensor elements to detect an array of gases. The Assembly reports once a minute, however the reporting rate will increase to once every five seconds when the detect gas is above the Background Gas Set-Point. Operates from an AC power supply with an internal backup battery pack. Magnetic switches allow for non-intrusive calibration while in the field as well as full system settings and diagnotics.
