CCX1000-type direct-reading dust instrument is measured β-rayabsorption method for the principle design of the dust concentration measuring instrument, which the respirable dustseparation unit of the separation performance of full compliance"BMRC" the requirements of international standard curve, accurate and timely reflection of personnel exposed to dust inhalation ofrespirable dust in different dust workplace quality and dust pollutionin the details
Products Name: CCX1000 direct reading instrument measuringdust CCX1000 type direct reading dust meter to measure β-rayabsorption method for the principle designed to overcome theaccuracy of other methods of measuring the dust by the dustmaterial, morphology, and air, water interference of the state. The use of low-energy β-ray source, without guards, lightweight and portable, easy to work-site dust measurements. It combines thedetection system, control system, power system, sampling system,SCM system as a whole, with the advanced jet digital flow sensor and the most advanced online programming-style SCM, with the completion of the sampling and measurement, rapid determination of dust in the field concentration, direct reading.
The instrument is suitable for coal mine dust, and other mines,workshops and other workplace dust measurements require any occasion, small size, light weight, high precision, accurate measurement, easy, safe and reliable, is the most advanced dustconcentration measurement one instrument.
Direct-reading dust instrument measuring technical parameters:
● dust concentration measurement range: total dust 0.1-1000mg/m3;
Note: The measuring range can be adjusted by flow rate andsampling time to increase or decrease.
● dust concentration measurement relative error: <± 25%
● measurement system stability relative error: 2.5%
● Sampling flow rate: 15L/min
● Sampling flow error: not more than 5% of the total dust;respirable dust is not greater than 2.5%
● sampling flow changes less than 5%
● sampling error: the sampling time is equal to 1min, the error is less than 2%, the sampling time is greater than 1min, the error is less than 3S.
● respirable dust sampling efficiency in line with "BMRC" samplingefficiency curve, the error ≤ ± 5%.
● instrument in -10 ℃ -40 ℃ temperature and relative humidity less than 95% of the environmental conditions to work properly.
● type of instrument-based security riot |
