Sampling gases at pressures greater than sea level, such as 25 – 100 psi, is challenging for particle counters. Connecting pressurized air or gas to a particle counter can defeat its flowmetering system and possibly damage the instrument.
High Pressure Diffusers (HPDs) have been developed to address particle counting in compressed gas. HPDs reduce the pressure of the gas to about atmospheric pressure by allowing some of the air/gas to diffuse out of the system and allow the Lasair III particle counter’s flow-metering system to function as designed.
