Based on the principle of filter trapping, model HRH-DSA350 is a high-flow, high-efficiency, portable, and weatherproof gas sampler for collecting bioaerosol particles e.g., bacteria, viruses, fungi, bacilli, etc. It consists of a sampler and an eluent which can quickly form liquid samples onsite. Airborne biological particles are collected on electrostatic filter by the sampler and then extracted by eluent in a sampling liquid bottle.
Sampling flow: 100-300L/min adjustable.
Sampling efficiency:
Sampling efficiency≥70% when particle size≤0.5μm.
Sampling efficiency ≥75% when particle size is 0.5-1μm.
Sampling efficiency≥95% when particle size≥2μm.
Sample form and volume: forms liquid sample onsite by eluent within 1 min, which can be used for subsequent analysis.
Working conditions: -40℃ ~ 70℃.
Power duration: unintermittent operation ≥ 24h after fully charged.
Control: supports wireless control and networking control.
Sampling mode: four modes are available, including manual, auto, hardware triggered, and software triggered.
Weight: sampler <3kg (with batteries).
EMC: GJB151B-2013 compliant.
Software can set a. sampling rate b. sampling volume c. sampling period and interval d. sampling starts delay e. number of sampling cycles f. device number g. network search. Real-time display: running time, number of completed cycles, sampled flow, remaining time, etc.
Three-proof packaging: standard configurated three-proof packaging is easy for transportation.
