Certified calibration test gas formulated for trimix diver gas analyzers. Contains 18% oxygen (O2), 50% helium (He), and 32% nitrogen (N2) in a 17 L (0.6 cu ft) cylinder with a CGA 600 valve. Requires a compatible CGA 600 regulator, sold separately. 

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 (like the 400-100 Calibration Test Gas Regulator) may be required.

Due to government regulations, shipping of compressed gases requires special handling and extra costs depending on the ship-to address. Please contact the Nuvair sales team for assistance with ordering test gases.
