Purpose: Mainly used for collecting samples of total suspended particulate matter (TSP), inhalable particulate matter (PM10, PM2.5), fluoride, benzo [
Product details
Purpose:
Mainly used for collecting samples of total suspended particulate matter (TSP), inhalable particulate matter (PM10, PM2.5), fluoride, benzo [a] pyrene, and other pollutants 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. Using flow, pressure, temperature sensors, and microcontroller measurement and control technology to automatically control the flow of the vacuum pump and achieve constant flow sampling
2. Able to automatically measure environmental temperature, atmospheric pressure, flow rate and other parameters
3. Able to digitally set parameters such as sampling flow rate (operating conditions), sampling time, interval sampling time, sampling volume, etc
4. Able to digitally calibrate values such as flow rate, temperature, pressure, time, etc
5. Automatically display, accumulate, and store values such as standard condition sampling volume (273.15k, 101.325kPa), operating condition volume, and sampling time
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. Adopting a brushless fan, it has a long service life, can run for 20000 hours without faults, and has low noise
10. One machine with multiple uses, capable of selecting particle cutters with different working point flow rates for sampling within the flow range of (15~140) L/min
