Introduction: The ZR-3960 ambient air aerosol sampler is designed with reference to HJ/T 374-2007 "Technical Requirements and Testing Methods for Total Suspended Particulate Matter Sampler", which can be used to collect total suspended particulate matter (TSP), inhalable particulate matter ( Sampler for samples such as PM10, PM2.5) and benzo[a]pyrene. The whole machine is easy to operate, stable in flow and reliable in operation. It is suitable for routine monitoring or research work on the atmosphere by relevant departments such as factories and mines, environmental protection, labor health, scientific research, and meteorology. Features: 1. Using embedded ARM single-chip microcomputer control technology and orifice flowmeter sensing technology, it has hardware clock timing and automatic constant current sampling functions; it can digitally set quantitative sampling volume, instantaneous sampling flow, sampling time, and automatically display working condition flow, Sampling time, start time, ambient temperature, atmospheric pressure, pre-meter pressure, automatic cumulative volume. Among them, the cumulative sampling volume can display the standard condition volume, the working condition volume and the reference volume. 2. Can digitally calibrate date and time, ambient temperature, pre-meter temperature, differential pressure, pre-meter pressure, atmospheric pressure, and instantaneous flow. Among them, the instantaneous flow has a segmented calibration function to improve the accuracy of the flow in the entire range. 3. Using brushless pumping power and PWM control technology, it has long service life and low noise. 4. The sampling time can be set arbitrarily within 24 hours, and the maximum sampling volume is 9999 999.99m3. 5. With quantitative, immediate, timing, interval sampling functions. 6. Large-screen Chinese display, man-machine dialogue, simple operation and convenient use. 7. Overload automatic protection function. During the sampling process, when the sampling flow rate cannot reach 90% of the set sampling flow value or exceeds 110% of the set value for 5 consecutive minutes, the sampling data will be automatically saved and sampling will be stopped. 8. Power failure protection function: when the power is cut off during the sampling process, the sampling data can be automatically saved, and the sampling will continue after the power is turned on. 9. Sampling imported fan, long service life, can run for 20,000 hours without failure. 10. Can store 100 sets of sampling data. Technical parameter: Power consumption: <300W Power supply: AC (220 ± 22) V, (50 ± 1) Hz, optional portable lithium-ion AC and DC power supply Host size: When working (length 505 × width 280 × height 1240) mm, the host is upside down when transported, and the height is compressed to 810mm Weight: about 25kg
