Air Purity Test Kit

Air Quality Testing for compressed air systems

Air Purity Test Kit

allows for a convenient ‘on the spot’ indication of compressed air quality. This comprehensive test kit is compact, easy to operate and can be used to indicate the level of contamination both upstream and downstream of purification equipment.

It is supplied complete with oil mist, water vapour CO and CO2 test tubes to allow immediate multiple testing.

In addition to the detection of compressed air contaminants listed above, the domnick hunter APTK1 also features an Oxygen Analyser allowing for constant real-time display of the oxygen content within the compressed air system.

The domnick hunter APTK1 is not only suitable for industrial compressed air testing but also, the additional O2 analysing feature enables compressed air lines that supply Breathing Air / Respiratory Protection Equipment (RPE) to be tested to the latest national & international standards.
