• It is composed of double membrane pump (imported) and double gas path. Each channel is used independently with high reliability, long service life and strong load resistance;

• The instrument has the function of automatic real-time measurement of ambient atmospheric pressure and ambient temperature;

• The microcontroller can keep the current automatically according to the set flow rate;

• The instrument can realize the simultaneous sampling or separate sampling of two gaseous pollutants, and can set the sampling mode of long time, fixed time, constant working condition volume and fixed standard volume；

• The two channels accumulate the sampling volume of working condition and standard condition respectively, store the sampling data in real time and query the historical data;

• It has the function of software calibration, which can calibrate the pressure, flow and other parameters of the instrument;

• The instrument is small in size, light in weight and easy to carry;

• The instrument can work more than 20 hours with DC battery.

Th-110e series atmospheric sampler (portable) is a dual channel automatic constant flow sampler with micro flow. The sampler is controlled by a microcomputer, which realizes the whole process of intelligent sampling, full Chinese interface, man-machine dialogue, automatic control, automatic volume conversion, simple and reliable operation. It is mainly used for indoor testing, environmental monitoring, third-party testing institutions, health and epidemic prevention stations, industrial and mining enterprises and scientific research institutes.
