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.

Stainless Steel Cut Wire Shot Conditioned
Stainless Steel Shot is a very useful Metal Abrasive for shot blasting, which could make die casting parts have a matte surface.
Generally, Stainless Steel Shot could be divided into two types. One is as cut one and the other one is conditioned one. The as cut one is obtained by cutting the stainless steel wire directorly. It has sharp edge and sometimes it may scratch the soft parts when shot blasting. So it is important to choose suitable Metal Abrasive. While for conditioned, usually there are three shapes and they are G1, G2, and G3. For our Longlived Stainless Steel Shot, there are even G4 one. It has been rounded four times and it is very similar with a sphere. It has a great effects on surface treatment.
