상품 소개

This compressed air particle counter combines an optical airborne particle counter with a passivated stainless-steel high-pressure diffuser. The diffuser reduces line pressure to near atmospheric conditions while maintaining a controlled sample flow to the counter, protecting the optical system and avoiding flow-related counting errors. Gas-specific volume correction and isokinetic-style sampling options support meaningful cleanliness assessment for clean dry air, nitrogen and compatible inert gases.

주요 기능

Pressure-reducing diffuser enables safe particle measurement from compressed-gas lines.

Controlled outlet flow matches the connected counter's calibrated sample rate.

Passivated stainless-steel wetted path minimizes particle shedding and chemical interaction.

Gas-specific correction accounts for density differences between calibration air and the sampled gas.

HEPA-protected exhaust reduces contamination ingress when the diffuser is disconnected.

Portable package supports testing at multiple utility points without permanent installation.

고객 제품 관심사

Pressurized gas must be reduced without adding particles, matched to the counter's intake flow, and interpreted for the density of the sampled gas.

Direct high-pressure connection can overload or damage a standard particle counter.The dedicated diffuser reduces pressure and delivers the counter's required sample flow near atmospheric conditions.

Different gas densities can distort the calculated sample volume.Gas selection and specific-gravity correction normalize measured flow for the sampled medium.

Pressure reduction hardware may introduce particles into an otherwise clean sample.A passivated stainless wetted path and protected exhaust minimize shedding and contamination ingress.

Large particles may be lost when gas velocity changes abruptly.An isokinetic-style diffuser configuration controls the transition and preserves the sampled size distribution more effectively.
