TW-2200 Total Suspended Particulate/Integrated Particle Sampler Introduction
TSP particle sampler, comprehensive particle sampler, TW-2200 air/TSP comprehensive sampler uses solution absorption method to collect various toxic and harmful gases in the ambient atmosphere and indoor air, and uses filter membrane weighing method to capture total suspended particles (such as TSP, PM10, PM2.5, etc.) in the ambient atmosphere. It is widely used in environmental protection, occupational health, factories and mines, colleges and universities, scientific research and other institutions.

TW-2200 Total Suspended Particulate/Integrated Particle Sampler Particle Sampler

• Electronic flowmeter, constant current sampling, two atmospheric channels and one particulate matter channel, any channel can be controlled and started and stopped separately;

• High-speed processor automatically calculates and controls the sampling flow, and automatically compensates for flow changes caused by voltage fluctuations and resistance changes;

• The atmospheric sampling gas circuit is equipped with an anti-backflow drying bottle to prevent the absorption liquid from backflow;

• Pipeline blockage protection function: During the atmospheric sampling process, if the pipeline is blocked or the load is too large, the system will automatically stop the pump to protect the instrument from damage due to long-term overload. If the load is greater than negative 20kPa for a long time, the protection function will be automatically started;

• Atmospheric sampling has a constant temperature automatic heating function;

• Atmospheric sampling uses a high-performance subwoofer brushless diaphragm pump with a long service life;

• Atmospheric sampling uses a red and blue dual-color gas circuit connecting pipe to easily and accurately connect the gas circuit;

• Automatic Measure ambient atmospheric pressure and temperature, display real-time sampling flow, cumulative sampling volume, standard volume;

• Built-in real-time clock, sampling start time can be pre-set;

• Timed sampling can be set, multiple sampling at equal intervals, sampling times can be set arbitrarily from 1 to 99 times;

• Brushless motor is used for particle sampling, strong resistance can be overcome, and continuous long-term work can be achieved;

• TSP/PM10/PM2.5 sampling head is made of aluminum alloy, anti-static adsorption;

• Power-off protection function, automatic sampling when incoming calls;

• Chinese LCD display with automatic contrast adjustment, can work normally at minus 30 degrees;

• External TW-DY2420 or TW-DY2440 portable AC/DC power supply can be used for sampling in the field without AC power supply;

• With RS232 digital communication interface, external printer can be connected for convenient data output.
