The product complies with GB/T15432-1995 Gravimetric Determination of Total Suspended Particulate Matter in Ambient Air; Enterprise standard Q/WTH43-2020 TH-3150 Ambient Air and Particulate Matter Combination Sampler.
Application Scope
The TH-3150 ambient air and particulate matter combination sampler is the latest portable on-site ambient air sampler developed by our company. Based on extensive expert advice and valuable user feedback, it integrates the functions and advantages of the TH-3000 and TH-150 series. The TH-3150 sampler is suitable for collecting particulate matter (TSP, PM₁₀, PM₅, PM₂.₅, etc.) and various harmful gas components (SO₂, CO, NOₓ, etc.) in ambient air.
Instrument Features
•The instrument integrates particulate matter sampling and gas sampling functions, enabling simultaneous sampling of particulate matter (TSP, PM₁₀, PM₂.₅, etc.) and gases such as SO₂ and NOₓ in ambient air;
•The instrument can collect four gas samples and one particulate sample simultaneously, with five channels independently controlled;
•Four-channel gas sampling uses multiple methods including industrial-grade electronic soap film for dual-channel automatic constant flow control;
•Uses microcomputer constant flow with industrial-grade diaphragm (balanced flow) constant flow technology for measurement, absorption bottles use full-wrap automatic constant temperature method with good constant temperature effect and long service life;
•Multiple sampling modes including conventional mode, interval mode, constant volume mode, scientific mode, etc., automatic calculation of standard condition sampling volume, supports timed and interval sampling with multiple sampling volume accumulation function and state conversion;
•Particulate sampling section uses DC brushless motor technology with long service life and low operating noise;
•Gas sampling section uses low-noise, high-performance imported DC brushless gas pump, with small pump recyclable and equipped with drying bottle to protect gas path from absorption bottle moisture influence;
•Built-in large-capacity memory for permanent storage of at least 50 groups of sampling data;
•Real-time clock display, power failure self-recovery sampling, with selectable power failure sampling compensation or non-compensation function;
•Software calibration function with user password protection;
•Power failure and power restoration log recording, with query and wireless printing functions;
•OLED wide-temperature LCD Chinese character display, ensuring normal operation in low illumination and low temperature;
•Gas path filtration and dehumidification protection device to effectively remove moisture interference on gas path;
•Automatically measures on-site atmospheric pressure and temperature for automatic participation in gas state conversion;
•Safety protection functions: overpressure alarm protection function, flow overrange alarm protection function, overrange protection threshold settable;
•Four-channel gas sampling can optionally use electronic flowmeter version.
