The Le600 constant flow air Sampling Pumps is a portable sampling device with a flow rate range of 10-600 milliliters per minute, which complies with the provisions of JJF1404-2013 "Outline for Type Evaluation of Atmospheric Sampling Pumpss" and JJG956-2013 "Verification Regulations for Atmospheric Sampling Pumpss".
The Le600 constant current air Sampling Pumps adopts the advanced closed-loop intelligent control system LeAiOS, achieving precise and stable constant current sampling.
This device is equipped with a color touch screen and excellent UI human-computer interaction design, which can achieve various sampling modes such as manual/timing/constant volume/programming. At the same time, it can also monitor flow, sampling volume, temperature, and pressure indicators in real-time, and will automatically alarm in case of errors.
In addition, it can calculate and record corresponding average values and STP standard volume data.
It has a compact body, long endurance, and can withstand a back pressure of up to 33kpa, meeting the requirements of various sampling specifications. It is suitable for various air sampling occasions such as individuals, fixed points, and laboratories.
