Product Name: direct-reading measuring dust instrument 

 Product Model: CCZ, in-1000 

 Coal safety sign: MFA070094 

 Description: 
 The product is a new generation of portable direct-reading dust concentration detector, the figures show the value of accurate measurement, stable performance, small size, light weight, simple operation, easy to use and so on. Can be widely applied in the working environment in the presence of flammable and explosive flammable gas mixture, the determination of total dust or respirable dust concentration 

 The main characteristics and uses: 
 CCZ, in-1000 type of direct-reading dust measuring instrument (hereinafter referred to as the measured dust analyzer), the use of microprocessor technology, fast data processing, strong anti-interference ability, good stability, high measuring accuracy. Dust measurement instrument with the classification of the dust catcher, collected respirable dust and total dust, and their separation performance to meet the requirements of the BMRC respirable dust separation efficiency standard curve. Chinese display, and can randomly record 50 historical test records. 
 Measuring dust instrument for the direct determination of total dust or respirable dust concentrations in coal mines or other dust operating environment. 

 How it works: 
 Membrane folders into a measuring dust instrument measuring dust instrument detection system to initialize the measurement of the blank membrane, and store the measured values. 5 seconds after measuring dust instrument sampling, the negative pressure of the suction pump will be pumped into the dusty air to the membrane on the accumulation of dust on the membrane, and the sampling synchronization timer start timing detection system according to the membrane on the dust The amount is automatically set the sampling time. When measuring dust instrument to stop sampling by the microcontroller for data processing and calculation of the dust concentration shown on the display.
