Pro Trio Multigas (O₂ · CO₂ · CO) Analyzer

$2,660.00

Designed for dive operators and tec divers who require simultaneous analysis of oxygen (O₂), carbon monoxide (CO) and carbon dioxide (CO₂) in breathing gases, the Nuvair Pro Trio multigas analyzer has visual and audible alarms that sound when alarm set points are exceeded. Equipped with an optional relay, the Pro Trio can shut down a compressor or sound external alarms when gases exceed threshold alarm settings. Available in three power options. Choose from 110/210V wall plug-in, 12V DIN rail powered, or rechargeable lithium battery with charger.

The Nuvair Pro Trio multigas analyzer measures oxygen (O₂), carbon dioxide (CO₂), and carbon monoxide (CO) levels in supplied gases. All analyzers are mounted in a water resistant, impact resistant case with a clear cover that allows for viewing of all gas displays, visual alarms, and easy access to analyzer controls. This unit is compatible with outdoor and marine environments.

The internal sensors are plumbed together to monitor a single input. The Pro Trio has visual and optional audible alarms for each of the gases monitored. An audible alarm will sound if any alarm set point is reached. If the alarm sounds, the analog output can activate an optional relay that shuts down compressors automatically, sounds a remote alarm, or activates emergency backup systems.

WARNING: Never expose gas sensors to pressure or you may cause damage and/or false readings. Damaged sensors will not provide accurate gas analysis. Most gas analyzers can be used to analyze a regulated gas sample flow, the contents of a gas cylinder, or the flow from a regulator. The flow rate of gas must equal 1-5 L/min. To produce this flow, a Flow Restrictor and Regulator (like the 400-100 Calibration Test Gas Regulator) may be required. A faulty Flow Restrictor can lead to a false analyzer reading. Flow Restrictors should be regularly tested with a Flow Meter. Inaccurate gas analysis can lead to serious personal injury or death.
