NUVAIR – Pro He and O2 Trimix Analyzer
The Pro He/O2 Trimix Analyzer represents the most economical and contemporary model for the analysis of oxygen (O2) and helium (He) in mixed gas with nitrogen. For an added cost savings, only one screen is used to cycle between He and O2 readings.
The Nuvair Pro He/O2 multigas analyzer for trimix divers is mounted in a rugged, water-resistant case. Each sensor has two user-programmable audible and visual alarms. Comes equipped with a rechargeable lithium ion battery and universal 110/230 V charger.
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.
