The product complies with HJ/T374-2007 Technical Requirements and Detection Methods for Total Suspended Particulate Matter Samplers; HJ/T375-2007 Technical Requirements and Detection Methods for Ambient Air Samplers; JJG956-2013 Verification Regulation for Ambient Air Samplers; JJG 943-2011 Verification Regulation for Total Suspended Particulate Matter Samplers; GB/T15432-1995 Gravimetric Determination of Total Suspended Particulate Matter in Ambient Air; Enterprise standard Q/WTH74-2025 TH-150F Intelligent Medium Flow Ambient Air Total Suspended Particulate Sampler.
Application Scope
This instrument is a newly redesigned instrument by our company, an improved version of the original TH-150 rotor flow version. All channels use electronic flowmeters for flow measurement, with smaller flow error and more accurate flow. The instrument includes two channels for ambient air sampling (can collect gaseous components such as SO₂ and NOₓ in ambient air) and one channel for particulate sampling (TSP, PM₁₀, PM₂.₅ with different cutters), with software interface operation consistent with the original TH-150 sampler for user convenience. The software has been rewritten, circuit redesigned, and structure and appearance redesigned, making it a completely new instrument.
Instrument Features
•Two channels for air sampling, one channel for particulate sampling, three channels operating independently with flexible sampling mode settings;
•High-precision electronic flowmeter with closed-loop feedback automatic constant flow, automatically compensating for flow changes due to load variations;
•Uses imported brushless sampling pump for more stable flow, greater durability, and low noise;
•Wide-temperature OLED display screen with better adaptability, suitable for normal operation in extremely cold regions and high-temperature, high-humidity tropics;
•Sampling data automatically saved, optional Bluetooth printer for real-time printing of sampling data, with automatic printer pairing supporting one-to-many printing;
•Automatically accumulates sampling volume, with real-time viewing of accumulated working condition volume and standard condition volume;
•Sampling pump protection: automatic flow overrange and overload alarm protection to ensure sample validity;
•Power failure sampling data automatic protection, automatic sampling resumption upon power restoration;
•Optional external DC power interface; if no mains power at sampling site, optional high-capacity lithium battery backup power allows more than 30 hours of continuous operation under full load;
•Wide-range atmospheric pressure sensor, automatically measures on-site atmospheric pressure, suitable for high-altitude areas.
