Description
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.

Features

• 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.
