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.

2-Gas Options: Hydrogen Sulfide (H2S) and Combustible Gas - Methane - (LEL)
4-Gas Options: Hydrogen Sulfide (H2S), Combustible Gas - Methane - (LEL), Carbon Monoxide (CO), and Oxygen (O2).

Note: The OI-6940 unit can be customized to detect a variety of gases. See the "Gas Chart" tab for the full list of gases. Please call 1-800-333-3331 for more information.

Options: Additional radio options are available. Please call 1-800-333-3331 for more information.
