Pro Trimix Alarm Analyzer

Used by technical divers for multigas analysis, the Nuvair Pro Trimix Alarm measures helium (He) and oxygen (O2) levels in mixed gases. Self-calibrating with audible and visual alarms. With an optional relay, the Pro Trimix Alarm can shut down a compressor at user-defined set points.

The Nuvair Pro Trimix Alarm is a multigas analyzer that measures helium (He) and oxygen (O2) levels in either mixed breathing gases stored in gas cylinders or from compressor's continuous gas flow. The analyzer is compatible with outdoor and marine environments, is self-calibrating and includes user-defined audible and visual set point alarms. If the alarm sounds, the analog output can activate an optional relay to shut down equipment automatically, sound a remote alarm, or activates an emergency backup system. Range: 0-100% with display accuracy of ±2%.

PLEASE NOTE: Never expose gas sensors to pressure or you may cause damage and/or false readings. Damaged sensors will not provide accurate gas analysis. Inaccurate gas analysis can lead to serious personal injury or death. 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 may be required.
