Airtester HP, MP and Detector Tubes

In conjunction with Airtester HP [high pressure 200 bar and 300 bar] or Airtester MP [medium pressure up to 10 bar; 145 psi] the HP and MP Detector Tubes are used to monitor the purity of breathing air as supplied from compressors, pressure cylinders or medium pressure air lines.

The HP and MP Detector Tubes can indicate quickly and quantitatively the concentration of water vapour, oil, carbon dioxide, carbon monoxide, nitrous fumes according to quality requirements of European Standard DIN EN 12021 [01/99].
