Thông tin chi tiết

Electrostatic Dust Meter


☆ Adopt mixed signal processing method, strong anti-interference ability

☆ Easy to use  The dust contamination of the probe do not affect the measurement sensitivity,

☆ By intelligent successive approximation algorithm, it can adapt to more working conditions


Charge transfer occurs when two objects rub or touch.The device adopts accurate and reliable AC electrostatic measurement technology.When the dust particles pass through the sensor, the weak charges carried by the dust particles are collected by the sensor and sent to the processor. The processor converts the signal processing result into an output value that is linearly related to the dust content.
