Pro He Alarm Analyzer (Helium) – Handheld with Rechargeable Lithium Battery
The Pro He Alarm Analyzer measures helium in mixed gases. This analyzer includes two audible and visual alarms for high and low helium percentages, and an analog output for shutting down your compressor automatically with an optional relay. Compatible with heliox and trimix.
The Pro He Alarm Analyzer measures helium (He) in mixed gases. The unit comes with two user-defined visual and audible alarm set points, one high and low. If the alarm sounds, the analog output can activate an optional relay that shuts down compressors automatically, sounds a remote alarm, or activates an emergency backup system. Does not require calibration. Can be used as a continuous reading analyzer while mixing gas. Price varies according to power option selected.
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.
