Dust particle counter calibration device

SPC-CB870V4 Standard Particle Generator

Dust particle counter calibration deviceThe SPC-CB870V4 standard particle generator is a device developed based on the national standards "Performance Test Methods for Dust Particle Counter" GB/T6167-2007 and "Calibration Specification for Dust Particle Counter" JJF1190-2008. It absorbs domestic and foreign testing methods for dust particle counter calibration, and combines our company's accumulated experience in long-term production and calibration of dust particle counters to produce a certain concentration of standard particles for specialized calibration of dust particle counters

The standard particle generation device consists of four standard particle atomization headsIt can provide standard particles with four different particle sizes.

1Main functions:

1Can be used for the generation of various aerosols.

2Can be used for metrological calibration, calibration, factory testing and verification of laser dust particle counters.

3Generate a concentration adjustable and stable suspended standard particle gas.

4Provide an ultra clean environment to prevent contamination of standard particles during the filling process and occurrence.

IIMain components:

1、The verification device mainly consists of a standard particle generator and a standard particle diluentClean air supply unit.

2、Composition of standard particle generation device.

3、Device shell The shell is made of stainless steel plates welded or painted with steel plates and has relevant indication marks. It is mixed and distributed The device is composed of stainless steel pipes.

4、Device structure The device adopts the principle of a biological clean workbench shell to calibrate the dust particle counter and generate device shapes Create a positive pressure clean space. When configuring or adding particles, it prevents external cross contamination.
