◆ Adopt imported wide temperature OLED display, Chinese menu, good human-computer interface, easy to operate

◆ The electronic flowmeter made of imported sensors can automatically compensate for flow fluctuations caused by changes in voltage and resistance, and constant current sampling

◆ Simultaneous collection of particulate and gaseous SVOCS in ambient air

◆ 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

◆ Imported high negative pressure brushless motor air pump, long-term continuous work with high reliability, low noise, and trouble-free running time greater than 10,000 hours

◆ The flow adjustment range is large, which can be set arbitrarily from 225L/min to 1150L/min, meeting the requirements of the national standard

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

◆ With power-off protection function, it will automatically enter the sampling state after power-on, with the functions of power-off deduction and power-off compensation time

◆ Fault self-checking function, convenient for users to detect, maintain and use

◆ Intelligent software design, online prompt navigation, guide users to complete various operations

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