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 376-2007 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 (constant temperature) 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, with automatic constant temperature collection for gas samples, 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;
•Gas sampling automatically maintained at constant temperature of 24±2℃;
•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.
