KQET-03 Independent Pump

The KQET-03 independent pump is an air pump used in online monitoring systems, with a maximum flow rate of 100L/min. It can be connected to high-flow remote airborne particle counters and remote bioaerosol samplers respectively, and can communicate with the upper computer monitoring software via the 485 protocol.

The independent pump body is made of 304 stainless steel, meeting the requirements of GMP specifications. It is equipped with a built-in air pump with a 3-year long service life, featuring low vibration and low noise.

Meanwhile, it adopts a precision digital flow sensor to monitor the sampling flow in real time. Through an intelligent algorithm, it achieves the function of flow negative feedback automatic adjustment, ensuring the stability of the sampling flow without being disturbed by the environment and guaranteeing the accuracy of sampling results.
