Product Description

Product profile of TW-2200B Intelligent Total Suspended Particle Air Sampler
The instrument uses the filter membrane weighing method to capture the total suspended particles in the ambient atmosphere (such as TSP, PM10, PM2.5, etc.). Widely used in environmental protection, occupational health, factories and mining enterprises, colleges and universities, scientific research and other institutions.
Technical Feature of TW-2200B Intelligent Total Suspended Particle Air Sampler
■ With a real-time clock, can set the timing sampling, equal interval multiple sampling;
■ TSP / PM10 / PM2.5 sampling head is made of aluminum alloy, antistatic adsorption;
■ Automatic measurement of temperature and air pressure, automatic calculation of the standard condition sampling volume;
■ Small volume, light weight, easy to carry;
■ Large size Chinese dot matrix LCD screen, with the temperature, automatically adjust the contrast of the LCD screen, can work normally at minus 20 degrees;
■ Power loss protection function, power call automatic sampling;
■ With RS232 digital communication interface, it can be connected to the external thermal printer, convenient for data output.
