The only such system approved for use in Zone 2 explosion hazard areas – for safe, easy and accurate compressed gas sampling. Overview Our MAS-100 CG Ex® system is for use when there is a need to test compressed gases for microbial contamination. In fact, it is the only compressed gas microbial air sampler approved for use in Zone 2 explosion hazard areas. Using its two sensors, one to measure mass flow and the other for pressure, the unit collects samples under the pressure of the gas supply. The unique MAS-100 CG Ex® system makes compressed gas sampling safe, easy and accurate. Secure and reliable: Fully validated according to EN ISO 14698 Collects samples under gas pressure; after sampling, gradual decompression occurs, avoiding possible damage to microorganisms Sampling at two different flow rates: usable for low flow applications The only compressed gas microbial air sampler approved for use in Zone 2 explosion hazard areas Convenient: Automatic calibration function: reduces the risk of errors Unique mass flow sensor technology: no need to calibrate for specific gases Automated collection process: saves you time Flexible: Pre-programmed for a range of different gases: no further calculations needed Can store up to 10 gas protocols
