Designed for microbiological sampling and particle monitoring in compressed gases. Sampling before decompression eliminates the possibility that the microbe will burst due to a sudden drop in pressure.
Automatic sampling — no need to monitor the pressure and sampling time, making sampling convenient and safe. Built in flow and pressure sensors ensure proper sampling speed and actual sampling volume. Covers the most common gases used in industry. The rotameter is not required.

Applications
DHPD can inplement two sampling modes, which are used for microbial sampling and particle monitoring of compressed gasses.
Application 1: Microbiological detection for compressed gas (Sampling Before Decompression)
- After passing through the sampling/detecting device, the compressed gas flows through the DHPD and is decompressed into an atmospheric pressure for release.
Application 2: Particle (airborne particle) detection for compressed gas (Sampling After Decompression)
- The compressed gas is decompressed into an atmospheric pressure when flowing through the DHPD, and then is output to the back-end sampling/detecting device for sampling or detection.
