Liquid particle counters are precision electronic measuring instruments that are not afraid of use, but afraid of release. Especially during rainy seasons, if stored without electricity for a long time, it may become damp and cause short circuit faults; On the other hand, some components in the instrument (especially electrolytic capacitors) may also experience leakage and deterioration if they are not powered for a long time. Special reminder, if the instrument you are using is equipped with a battery, the battery is also prone to damage during long-term storage. If the circuit board is corroded due to battery leakage, it will not be worth the loss.

Liquid particle counters should be used frequently, and instruments that are not used for a long time should also be powered on regularly or irregularly. After being powered on, the electronic components on the electronic circuit board will heat up, thereby eliminating moisture and preventing short circuit faults from occurring.

Due to its compact structure and inconvenient disassembly, portable liquid particle counters are difficult to clean after sensor blockage. Therefore, a protective filter element is generally installed at the instrument inlet to intercept larger particles in the measured liquid sample and prevent sensor window blockage. During the use of the protective filter element, it will continuously block larger particles due to interception. Once blocked to a certain extent, it will affect the passage of smaller particles, thereby affecting the accuracy of the detection results. Therefore, the protective filter element of the sensor should be cleaned regularly. After removal, the large particles and fibers intercepted on the surface of the filter element should be removed first, and then ultrasonic cleaning should be used.
