1. Product Overview
KQET-03 independent pump is an air pump used in online monitoring systems, with a maximum flow rate of 100LPM. It can be connected to a large flow online particle counter and an online planktonic bacteria sampler, and can communicate with the upper computer monitoring software through the 485 protocol.
The independent pump body is made of 304 stainless steel material, which meets GMP specifications. Equipped with a built-in long-life fan, it can work continuously for more than 10000 hours, with low vibration and low noise. At the same time, precise digital flow sensors are used to monitor the sampling flow in real time. Through intelligent algorithms, the negative feedback self adjustment function of the flow is achieved, ensuring the stability of the sampling flow, not being affected by environmental interference, and ensuring the accuracy of the sampling results.
