• According to different flow range and load capacity, the instrument is divided into three different versions, which are equipped with different power brushless fans;
• The error of sampling flow rate is better than 2%, the instrument is automatic constant current, the adjustment accuracy is 0.01/min, and the constant current stability is better than 0.5%;
• The instrument uses brushless DC motor, the service life is more than 10000 hours, the failure rate is low and the load capacity is strong;
• With power down data saving function, automatically save the parameters, can continue to sample after the call;
• The instrument can measure and save the atmospheric pressure, temperature, system load, flow and other parameters, and can automatically count the actual cumulative volume, calculate the accumulated volume under standard conditions and save it
• The instrument can use manual sampling and automatic sampling. Automatic sampling can set the cycle sampling days of a week according to the needs, and the starting time and the starting time of five sampling sections can be set every day For manual sampling, the sampling time can be set immediately;
• Sampling function can be set with "interval sampling" and "time compensation sampling". In "interval sampling" function, the instrument can be set to stop sampling for a period of time after continuous sampling, and follow this cycle
• Until the end of sampling, this function can also be turned off if it is not needed; "time compensation sampling" function refers to whether it is necessary to make up the sampling time when the instrument is powered down User requests to open or close;
• The instrument is equipped with flow and load alarm functions, which will alarm when the flow cannot reach or the load exceeds the limit;
• The instrument can be equipped with printer to print current or historical sampling data;
• The instrument adopts rainproof design and can be used for 24-hour unattended sampling.

Th-1000c Ⅱ intelligent large flow air particle sampler is a necessary instrument for environmental monitoring departments to collect atmospheric particulate matter (TSP, PM 10, PM 2.5, etc.). The instrument is mainly used in environmental monitoring, environmental assessment sampling and scientific research experiments; it is suitable for 24-hour continuous large flow total suspended particulate matter sampling - unattended all-weather work according to the new monitoring specification. Super large flow pump is the biggest feature of this product.
