DE-OX ZIP PRO Oxygen Analyzer


DE-OX ZIP PRO oxygen analyzer is designed for measurement of oxygen in a mixed gas. The alarms featured in this model include two audible alarms for high and low percentages and an analog output for shutting down and/or setting off external alarms for your compressor automatically (with optional relay). Compatible with nitrox, heliox and trimix.


DE-OX ZIP PRO represents the simplest and up-to-date measurement instrument for the analysis of oxygenate mixed gas. Unique features include two audible alarms (minimum and maximum), standard analog 4-20 mA and open collector outputs. Specially designed and manufactured for the analysis of binary and ternary gas mix (like nitrox, heliox and trimix), for detection of oxygen in any environment (hyperbaric, saturation, etc.). Oxygen sensor, the electronic board and the battery are integrated in one device.

The instrument can be automatically calibrated in any known gas mix for giving the less error. DE-OX ZIP PRO can be used for continuously reading during mixed gas filling. It can alert and help in switching off the compressor if the oxygen value goes out the set alarms range (for instance, 40% oxygen).

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 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.
