Price on request


Nuvair Carbon Monoxide analyzers are designed to detect levels of CO that could be harmful to a diver before the gas reaches them. Our CO analyzers can be attached to a high pressure compressor to monitor tank fills or inline on a low pressure compressor that is providing surface supplied air to a diver. The analyzers offer both visual and audible alarms to warn the compressor operator of potential CO hazards in the breathing air being supplied. It includes an 11.1 Volt Lithium Battery & Charger and comes in a Black Plastic Weatherproof Case. It is also equipped with a loud Piezzo alarm & alarm light and SPDT Relay NO & NC cable for use to shutdown compressor or sound alarms.
