Main Features and Uses
Direct-reading dust detector (hereinafter referred to as dust detector The instrument adopts microprocessor technology, with fast data processing, strong anti-interference ability, good stability and high measurement accuracy. The dust detector is equipped with a graded dust collector, which can collect respirable dust and total dust, and its separation efficiency meets Requirements for the international standard curve of respiratory dust separation efficiency. Full Chinese display, and can randomly record the previous historical test records.
The dust meter is suitable for coal mines or other dust operating environments to directly measure total dust or respiratory dust concentration. .
Working Principle
After the filter membrane clip is placed in the dust detector, the detection system in the dust detector initializes the measurement of the blank filter membrane and stores the measurement value. After seconds, the dust detector starts sampling and pumping The negative pressure formed by the operation of the air pump draws the dusty air into the filter membrane, causing dust to accumulate on the filter membrane. A timer synchronized with the sampling starts, and the detection system automatically sets the sampling time according to the amount of dust on the filter membrane. When measuring dust After the instrument stops sampling, the microcontroller will process the data and calculate the dust concentration and display it on the display.
