Performance characteristics

◆ Equipped with a wide temperature LCD display screen, Chinese menu, and illustrated text for easy operation

The flow monitoring adopts high-precision sensors with good flow stability and high sampling accuracy. It automatically detects the sampled flow rate, controls constant current sampling, and compensates for flow fluctuations caused by voltage and resistance changes

Automatically record the cumulative flow rate and time during the sampling process, and convert the standard volume based on air pressure and temperature

Real time clock, can set multiple sampling methods such as timed sampling, interval sampling, multiple sampling, cyclic sampling, etc

◆ Save data during power outages, automatically restore sampling during communication calls, deduct power outage time during the sampling process, and allow users to query power outage time

◆ Brushless motor vacuum pump, with high long-term continuous operation, low noise, and a fault free operation time of more than 10000 hours, with a long service life

Both PM10 and PM2.5 cutters are made of aluminum alloy material, which has anti-static adsorption

Automatically save the last user set parameters, and use them automatically the next time the device is turned on, achieving one click sampling. Can store 10000 sets of data, convenient for users to query

◆ Automatic fault protection function, automatic shutdown protection if the set flow rate is not reached within the specified time

Users can calibrate the instrument through a waterproof keyboard, and maintenance requires password access to ensure the security of instrument data

◆ Unique rainproof design suitable for any environment, with a foldable flip structure for easy transportation
