Compressed Breathing Air Measurement Kit

Quick impurity measurement for compressed breathing air

Gastec CG-1 system can simply, quickly, and simultaneously measure 4 kinds of harmful contaminants (CO, CO2, Water vapour, and Oil mist) contained in compressed breathing air (cylinder or compressor).

  • Accurate simultaneous measurement of 4 impurities (CO, CO2, Water vapour, and Oil mist) in compressed breathing air achieved by simply connecting the device to a cylinder or compressor
  • Easy measurement without any electricity or power source
  • Handy carrying case for storage and easy portability

Optional products (a dedicated pressure reducer, area flow meters, and a conversion adapter) stored in the carrying case.

Connect the pressure reducer to a cylinder or compressor
