Main Features
Instantaneous, timed sampling and various sampling modes such as equal interval can be set
Multi-functional design for TSP and PM10/PM2.5 sampling, featuring a tipping bucket rainproof structure for easy transportation and carrying
The cutter is made of aluminum alloy and has a compact structure to effectively prevent static electricity adsorption
Real-time monitoring of pressure and temperature, automatic compensation of flow deviation, further optimization of flow accuracy
Equipped with brushless DC sampling pump, no spark, low noise, long service life, greatly improve stability, easy maintenance
The dot matrix wide-temperature, high-brightness VFD display features a broad operating temperature range, enabling excellent human-machine interaction.
Automatically calculate the sampling volume and convert it to standard conditions based on air pressure and temperature.
Automatically detect AC power failure, save operation data, and automatically resume sampling after power supply
Sampling is complete. The sampled data is stored according to user requirements and can be queried or printed at any time (optional).
The preset parameters of the last sampling are automatically saved and used in the next sampling; 40 sets of sampling data can be saved for users to query
The built-in electronic tag enables intelligent management of instruments by integrating with the instrument inventory management platform software.
