• The instrument integrates the functions of particulate matter sampling and gas sampling, and can simultaneously sample particulate matters (TSP, PM10, PM2.5, etc.) and SO2, NOx and other gases in the ambient air;

• The instrument can collect four gas samples and one particulate matter sample at the same time;

• Industrial electronic (semiconductor) constant temperature technology is adopted for four channel gas sampling. Double channel temperature measurement is adopted. The absorption bottle adopts full package automatic constant temperature mode, with good constant temperature effect and long service life;

• The gas dynamic principle of micro hole constant current and the automatic constant current control combined with feedback steady flow are adopted;

• The sampling volume of standard condition can be calculated automatically by setting various sampling modes such as conventional mode, interval mode, constant product mode and scientific mode. The sampling volume of standard condition can be calculated separately, and the function of multiple sampling volume accumulation can be realized, and the state conversion can be carried out;

• The technology of Brushless DC motor is adopted in the sampling part of particulate matter, which has long service life and low noise;

• The gas sampling part adopts low noise and high performance imported DC brushless gas pump, which can be recycled and equipped with drying bottle to protect the gas path from the influence of absorption bottle moisture;

• The built-in large capacity memory can realize the permanent storage of at least 50 groups of sampling data;

• Real time clock display, self recovery sampling after power failure, with the function of sampling compensation or no compensation after power failure;

• Software calibration function with user password protection;

• Power failure, call log record, with query, wireless print data function;

• OLED wide temperature LCD Chinese character display ensures normal operation of the instrument under low illumination and low temperature;

• It has a gas path filtering and dehumidification protection device, which can effectively remove the interference of moisture on the gas path;

• Automatic measurement of atmospheric pressure and temperature, and automatic participation in gas state conversion;

• Safety protection function: pressure overload alarm protection function, flow overrun alarm protection function, the threshold value of limit protection can be set.

• The electronic flowmeter version can be selected for four gas sampling.

Th-3150 atmospheric and particulate matter combined sampler is a newly developed portable field air sampler. On the basis of widely listening to experts' suggestions and users' valuable opinions, the design integrates the functions and advantages of th-3000 and th-150 series. Th-3150 sampler is suitable for collecting particulate matter (TSP, PM10, PM5, PM2.5, etc.) and various harmful gas components (so, Co, no, etc.) in ambient air.
