Dust analyzer with a portable digital dust analyzer, direct-reading instrument measuring dust dust, coal mine dust analyzer, mine dust analyzer, direct reading instrument measuring dust, dust explosion-proof digital measuring instrument.
There is always too much dust in the mine, but in the end, there is a need for professional instruments to measure the amount of dust. The CCZ-1000 dust concentration measuring instrument is used to directly measure the total dust and respiratory dust concentration in coal mines or other dust working environments. .
The CCZ1000 direct reading dust detector consists of a sampling head, a detection device, an intrinsically safe power supply, a single chip system and a gas quality sensor.
Specific parameters:
a) Working temperature: 0 ° C ~ 40 ° C;
b) relative humidity: atmospheric pressure ≤ 95%;
c) atmospheric pressure: 86kPa ~ 110kPa;
d) Coal mines that contain gas or coal dust explosion hazards.
