The product complies with GB/T15432-1995 Gravimetric Determination of Total Suspended Particulate Matter in Ambient Air; JJG943-2011 Verification Regulation for Total Suspended Particulate Matter Samplers; Enterprise standard Q/WTH 35Y-2023 TH-1000 Series Intelligent High Flow Ambient Air Particulate Matter Samplers.
Application Scope
The TH-1000CII intelligent high flow ambient air particulate matter sampler is an essential instrument for environmental monitoring departments to collect particulate matter (TSP, PM₁₀, PM₂.₅, etc.) samples in the atmosphere. The instrument is mainly used in environmental monitoring, environmental assessment sampling, and scientific research experiments; suitable for 24-hour continuous high flow total suspended particulate sampling per new monitoring specifications — unattended all-weather operation. The ultra-strong flow suction pump is the biggest feature of this product.
Instrument Features
•The instrument is divided into three different versions according to different flow ranges and load capacities, each equipped with brushless fans of different power;
•Sampling flow error better than 2%, instrument automatic constant flow, adjustment precision 0.01L/min, constant flow stability better than 0.5%;
•The instrument uses brushless DC motor with service life greater than 10000 hours, low failure rate and strong load capacity;
•Built-in power failure data preservation function, automatically saves parameters and continues sampling upon power restoration;
•The instrument can measure and save on-site atmospheric pressure, temperature, system load, flow and other parameters, automatically accumulate actual cumulative volume, calculate standard condition cumulative volume and save;
•The instrument supports manual sampling and automatic sampling modes. Automatic sampling can set weekly cyclic sampling days, with up to 5 sampling segments per day including start time and duration; manual sampling only requires setting sampling duration to start immediately;
•Sampling function supports "interval sampling" and "compensated time sampling": "interval sampling" can set pause after continuous sampling for a period, cycling until end (can be disabled if not needed); "compensated time sampling" determines whether to compensate sampling duration after power failure and restoration, function can be enabled or disabled per user requirement;
•The instrument has built-in flow and load alarm functions, with alarm when flow cannot be achieved or load exceeds limit;
•Optional printer for printing current or historical sampling data;
•The instrument adopts rainproof design and can be used for 24-hour unattended sampling all-weather.
