◆Using wide temperature LCD screen, Chinese menu, pictures and texts, easy to operate

◆ Flow monitoring adopts high-precision imported sensors, with good flow stability and high sampling accuracy, automatic detection of sampling flow, automatic control of constant current sampling, and compensation for flow fluctuations caused by changes in voltage and resistance

◆ Automatically record the accumulated flow and accumulated time during the sampling process, and convert the standard volume according to the air pressure and temperature

◆ Real-time clock, which can set various sampling methods such as time sampling, interval sampling, multiple sampling, and cyclic sampling

◆ Save the data when the power is cut off, automatically resume sampling when the AC calls, automatically deduct the power-off time during the sampling process, and allow users to query the power-off time

◆ Brushless motor air pump, high reliability for long-term continuous operation, low noise, trouble-free running time of more than 10,000 hours, and long service life

◆ PM10 and PM2.5 cutters are made of aluminum alloy, anti-static adsorption

◆ Automatically save the parameters set by the last user, and use them automatically the next time the machine is turned on, realizing one-key sampling. It can store 10,000 sets of data, which is convenient for users to query

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

◆ The user can calibrate the instrument through the waterproof keyboard, maintenance requires a password to enter, to ensure the security of the instrument data

◆ Unique rain-proof design is suitable for any environment, and the flip-up structure can be folded for easy transportation
