Compressed Gas Detecting










Designed for compressed gas detection in GMP workshop

Working procedure of Electric High Pressure Diffuser-Economic (EHPD-ECO): when the sampling device starts, the EHPD-ECO decompresses the compressed gas to the similar atmospheric pressure gas dynamically in real time, and deliver the gas to the sampling device;when the sampling device stops, the EHPD-ECO close the outlet automatically.

The EHPD-ECO can be coupled with particle counter, air sampler and any other active sampling devices to be used for sampling and detecting the atmosphere, nitrogen, carbon dioxide, argon, oxygen and other inert gases under high pressure only in the non-flammable and non-explosive area.


- Accurate and reliable —— Flow rate depends on the needs of the sampling device

- Low contamination —— No emission of non-detected gas

- Low cost —— No gas spill except for the demand of the sampling device

- Good compatibility —— Compatible with particle counters, air samplers and any other sampling device

- Easy cleaning —— whole device produced with anodized aluminium

- Mobility —— Built-in rechargeable battery, with a whole weight of 0.8Kg

Application fields

This product is designed for industries that require critical standards of cleanliness, including food and beverage, pharmaceutical, cosmetic and medical industries. Compressed gases with relative pressure range from 2 up to 5bar may be connected directly to the instrument .
