The product complies with the technical requirements and testing methods of HJ/T374-2007 Total Suspended Particle Sampler and JG943-2011 Verification Regulations for Total Suspended Particle Sampler. Execute enterprise standard Q/WTH04-2013: TH-150 series intelligent medium flow air total suspended particulate matter (TSP) sampler.

　　Scope of application:
The TH-150C (TSP) medium flow air total suspended particulate sampler is a microcomputer intelligent TSP sampler developed to meet the needs of environmental monitoring and sampling: it is suitable for 24-hour continuous medium flow total suspended particulate sampling according to new monitoring standards - unmanned all-weather work. Using high-quality imported air pumps, with low noise and stable operation.

　　Instrument features:
High degree of intelligence, automatic constant current throughout the instrument sampling process, and automatic data processing;
Optional PM10, PM2.5, PM5, PM1 cutters are available for sampling, with cutters designed at 100L/min;
Automatically measure and display atmospheric pressure, and automatically calculate the working condition volume and standard condition volume. Six sets of sampling times can be set, and the sampling and measurement data can be checked at any time;
Fast response speed, in the sampling environment, when the resistance changes or the power grid fluctuates greatly, the flow rate returns to the preset value in about 8 seconds;
One machine for multiple purposes, combining medium flow particulate matter sampling and dual channel gas sampling (0.1-1 L/min) into one, capable of sampling medium flow particulate matter and atmosphere separately or simultaneously, with three channel times set arbitrarily;
Easy to use: The instrument is small in size, light in weight, and has a long lifespan, making it convenient for environmental monitoring in the field and high-risk areas;
Power failure protection, overload protection.
