Description
FEATURES:
1. Adopt brush-less control fan, with low noise and large load, suitable for continuous long-term work
2. The TSP/PM10/PM2.5/PM5/PM1 sampling head is made of aluminum alloy material, antistatic adsorption
3. Electronic flowmeter, constant current sampling
4. With a real-time clock, timing sampling can be set, and multiple sampling at equal intervals
5. Real-time monitoring of gauge pressure and temperature, automatic compensation of flow deviation, and optimization of flow accuracy
6. The Chinese LCD screen with automatic contrast adjustment is suitable for sampling in cold areas, and the popular software display interface realizes good human-computer interaction
7. Automatically calculate the cumulative sampling volume, and at the same time convert the standard sampling volume according to air pressure and temperature
8. Built-in rechargeable lithium battery to achieve both AC and DC use
9. A set of sample storage device is optional, which is convenient for sample collection and storage.
