The Otis Instruments Wire Free 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 detected 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 diagnostics.
