• Two / four channels flow are automatic tracking, digital flow display, digital flowmeter is used to measure the sampling flow, and the flow measurement and control is accurate;

• The microprocessor is used to control the pumping flow automatically, and the automatic constant current can be realized under the set flow rate;

• It adopts imported brushless air pump, which has low noise and high reliability;

• The full sampling mode can be selected by users, and the sampling parameters can be set arbitrarily;

• With the function of software calibration, the parameters such as flow rate, temperature and atmospheric pressure can be easily calibrated through the touch screen;

• 4.3-inch high brightness touch color screen displays parameters and operation, reliable and convenient;

• AC and DC dual-purpose, built-in rechargeable battery can make the instrument work more than 20h without commercial power;

• It has the function of saving power down data, automatically saves various parameters, and can continue sampling after calling;

• Automatic measurement of atmospheric pressure and ambient temperature, flow, pressure in front of the flowmeter and other parameters, automatic compensation for flow changes;

• The sampling flow and sampling time can be modified during the sampling process

• The sampling volume of working condition and reference state is automatically accumulated;

• The sampling bottle is heated automatically when the temperature is lower than 20 ℃;

• Two channel / four channel sampling data are stored and queried separately, each channel can store more than 500 groups of data separately;

• The instrument has overload protection function;

• The instrument can be equipped with printer to print current or historical sampling data;

• It has external DC power interface;

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

• GPS and instrument status upload functions are optional. After the instrument is powered on, it can automatically upload location information and instrument status information, and also upload historical data to the server for storage (mobile data operator service is required).

Th-110h atmospheric sampler is an intelligent instrument with automatic constant current, high accuracy and high reliability. It is designed and manufactured according to the actual requirements of sampling site. The instrument uses a 4.3 inch high brightness color touch screen as the human-computer interface. It is easy to operate and reliable in performance. It fully meets the sampling requirements of environmental monitoring, scientific research institutes and health and epidemic prevention departments.
