TH product complies with GB/T15432-1995 Determination of total suspended particulate matter in ambient air by gravimetric method; HJ/T374-2007 Technical Requirements and Testing Methods for Total Suspended Particle Samplers; HJ/T368-2007 Technical Requirements and Testing Methods for Orifice Flow Meters Used for Calibration of Total Suspension Samplers; JJG943-2011 Verification Regulations for Total Suspended Particle Samplers; Implement enterprise standard Q/WTH 35-2014: TH-1000 series intelligent high flow air particulate matter sampler.

　　Scope of application:
The TH-1000 series instrument can collect particulate matter (TSP, PM10, PM2.5) in the air, making it an ideal instrument for environmental particulate matter sampling. It has been recommended multiple times by the Ministry of Environmental Protection and the National Environmental Monitoring Center. The instrument has been redesigned in accordance with the technical requirements and detection methods for total suspended particulate matter samplers (HJ/T374-2007) issued by the Ministry of Environmental Protection of China. The advantages of similar foreign instruments have been referenced and borrowed, which has improved the service life of the instrument, reduced the labor intensity of monitoring personnel, and reduced maintenance costs for users.

　　Instrument features:
High degree of intelligence: using low-power microprocessors and high-precision micro pressure and temperature sensors, sampling and data processing are automatically completed;
Good environmental adaptability: all-weather rainproof exterior design, capable of constant current sampling when the power grid fluctuates or resistance changes, with a response speed of<5s;
Easy to operate: preset startup sampling, interval time, touch button, integrated electronic control box and panel, foldable bracket;
Data security and reliability: automatic protection of sampling data in case of power failure, and continuous sampling in case of incoming call;At any time, the average temperature, flow rate, cumulative (standard condition) volume, and cumulative time during the sampling process can be queried;
Flexible combination: PM10 and PM2.5 cutters can be optionally equipped for sampling different particulate matter.
