The product complies with GB/T 15432-1995 Gravimetric Determination of Total Suspended Particulate Matter in Ambient Air; JJG 943-2011 Verification Regulation for Total Suspended Particulate Matter Samplers; HJ/T374-2007 Technical Requirements and Detection Methods for Total Suspended Particulate Matter Samplers; HJ/T 375-2007 Technical Requirements and Detection Methods for Ambient Air Samplers; Enterprise standard Q/WTH 04Y-2023 TH-150 Series Medium Flow Ambient Particulate Matter Samplers.
Application Scope
The TH-150H medium flow ambient particulate matter sampler is a new medium flow particulate/gas combination sampler developed by our company with independent intellectual property rights. It uses a new energy-saving brushless pump and built-in battery to maintain 100L/min flow for continuous operation. It can complete sampling without stopping during mains power failure, making it an ideal instrument for environmental assessment and on-site monitoring.
Instrument Features
•Three-channel sampling flow with automatic constant flow and digital flow display, avoiding disadvantages of rotor flowmeters for gas sampling such as manual flow adjustment, inaccurate flow, and float drop;
•Uses original imported built-in suction pump with high reliability and strong load resistance;
•Configured with imported flow sensor to detect sampling flow, with microcontroller automatically compensating for flow changes caused by voltage and resistance variations for more accurate flow measurement;
•The instrument can sample one channel of particulate matter and two channels of gaseous pollutants simultaneously or separately;
•4.3-inch color touch screen for display and operation, clearly visible in sunlight;
•Three channels independently accumulate working condition sampling volume and reference state volume, with separate setting of sampling time and sampling flow for each channel;
•Features software calibration function, allowing convenient calibration of parameters such as instrument flow, temperature, and atmospheric pressure via touch screen;
•The instrument has storage, query, and printing functions (printer optional), with each channel capable of storing more than 200 groups independently;
•The instrument is small in size, light in weight, and easy to carry;
•Configured with DC battery, can operate for more than 20 hours (particulate sampling only, domestic glass fiber filter, flow 100L/min), meeting 24-hour valid sample requirements;
•External power interface.
