The Otis Instruments OI-6400 Series Ambient Air Quad Gas Detector is a versatile assembly that uses an electrochemical, infrared, PID, or a variety of each, sensor elements to detect a variety of gases. Includes an AC Power Supply with 6 foot cord to allow for quick installation and power-up.
The OI-6400 also includes a top mounted strobe light and bottom mounted miniature buzzer to alert when any control board is detecting gas above alarm levels. The strobe light is Red (Amber and Blue available). The Remote Sensor Kit version includes 4 remoted sensor housings with 50 feet of cable per housing.
4-Gas Options: Hydrogen Sulfide (H2S), Combustible Gas - Methane - (LEL), Carbon Monoxide (CO), and Oxygen (O2).
Note: This 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 light color options and a remote sensor kit available. Please call 1-800-333-3331 for more information.
