Features
4.3-inch color screen ,touch operation and the operation is simple
Compact size, light in weight, easy to carry
Built-in Lithium Battery
Four channels of simultaneous sampling can be used to collect particulate matter and gaseous pollutants in the air
Rain proof, dust-proof, anti-static and anti-collision design can ensure normal operation under the conditions of rain, snow, dust and heavy haze
Various sampling methods, such as constant sampling time, continuous sampling time and 24-hour sampling, can be realized
The cutter（TSP / PM 10 / PM 2.5） is made of aluminum alloy with anti-static adsorption
Power-off memory function,continue to sample procedure when recovery
Support data storage and export data with USB
Print with wireless Bluetooth
