Purpose:

Mainly used for collecting samples of total suspended particulate matter (TSP), inhalable particulate matter (PM10, PM2.5), benzo [a] pyrene, radioactive aerosols, etc. in the ambient air.

Adopting standards:

HJ 93-2013 "Technical Requirements and Detection Methods for Particulate Matter (PM10 and PM2.5) Samplers in Environmental Air"

JJG 943-2011 "Verification Regulations for Total Suspended Particle Samplers"

HJ 956-2018 "Determination of Benzo [a] pyrene in Environmental Air - High Performance Liquid Chromatography Method"

Main features:

1. Adopting embedded ARM microcontroller control technology and orifice flowmeter sensing technology, with hardware clock timing and automatic constant current sampling function; It can digitally set quantitative sampling volume, instantaneous sampling flow rate, sampling time, automatically display working condition flow rate, sampling time, start time, ambient temperature, atmospheric pressure, pre gauge pressure, and automatic cumulative volume. The cumulative sampling volume can display the standard condition volume, operating condition volume, and reference volume.

2. It can digitally calibrate date and time, ambient temperature, pre gauge temperature, differential pressure, pre gauge pressure, atmospheric pressure, and instantaneous flow rate. The instantaneous flow rate has segmented calibration function, which improves the accuracy of the flow rate throughout the entire range.

3. Adopting brushless exhaust power and PWM control technology, it has a long service life and low noise.

4. Sampling time can be set arbitrarily within 24 hours, with a maximum sampling volume of 9999 999.99 meters³It has the functions of quantitative, immediate, timed, and interval sampling.

5. Large screen Chinese display, human-machine dialogue, easy operation, and convenient use.

6. Overload automatic protection function: During the sampling process, if the sampling flow rate is greater or less than the set sampling flow rate, the instrument will automatically stop for protection.

7. Power outage protection function: During the sampling process, if there is a power outage, the sampling data can be automatically saved and the sampling can continue after the power is restored.

8. The sampling brushless fan has a long service life and can operate for 20000 hours without any faults.

9. Can store 100 sets of sampling data.
