Purpose:

It is mainly used to collect samples of total suspended particulate matter (TSP), inhalable particulate matter (PM10, PM2.5), fluoride, heavy metals, iodine, semi volatile organic compounds (SVOCs) and other substances 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"

HJ 691-2014 "Guidelines for Sampling Techniques of Semi volatile Organic Compounds in Environmental Air"

Main features:

1. Adopting imported high load brushless fans with strong load capacity, it can meet the requirements of high resistance filter membranes and adsorption materials, and can collect aerosol samples;

2. It can collect fluoride samples in the air, as well as TSP, PM10, PM5, PM2.5 and aerosol samples;

3. Adopting flow, pressure, temperature sensors, and microcontroller measurement and control technology to automatically control the flow rate of the brushless fan and achieve constant flow sampling;

4. It can automatically measure environmental temperature, atmospheric pressure, flow rate and other parameters; Digitally set parameters such as sampling flow rate (operating conditions), sampling time, interval sampling time, sampling volume, etc;

5. Automatically display values such as flow rate, sampling volume (standard condition, working condition, reference), temperature, pressure, sampling time, power outage time, etc;

6. Overload automatic protection: During the sampling process, if the sampling flow rate is less than or greater than the set sampling flow rate, the instrument will automatically shut down 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 sampling can continue after the power is restored;

8. Can store 100 sets of sampling data and power outage data, with a retention period of 10 years;

9. The data can be directly connected to a printer for printing or exported using a USB drive;

10. New connection of sampling head, fast and convenient;

11. Mold based production, high reliability, small size, and light weight.

12. The sampler is easy and simple to fix on the triangular bracket (patented technology).

13. The particle cutter, filter membrane clamp, and flowmeter are all patented technologies with independent intellectual property rights.

When necessary, the exhaust port can be connected to an extended exhaust pipe to discharge the sampled exhaust gas over a long distance, with good representativeness of the intake.
