Dust particle counter

Product Introduction:

The confidence measurement and verification standard of the dust particle counter automatically determines the purification level according to the conditions specified in the national standard GB/T6167-2007 and the calibration specification JJF1190-2008. One sampling can simultaneously measure the number of dust particles in six particle size channels and display the number and variation of particles in each channel.

Scope of application:

Satisfy the pharmaceutical industry (pharmaceutical factories, drug testing institutes, hospitals, etc.); The electronics industry (semiconductor factories, production and processing of precision machinery, etc.); Food hygiene industry (precision processing of dairy products, sealed meat products, seasoning foods, agricultural products, etc.); The manufacturer of the filter (to inspect the quality and efficiency of the filter, etc.); The inspection of clean rooms (areas) required for precision machining and precision testing in fields such as optics and aerospace.

According to the standard:

National standard: GB/T6167-2007 Performance test method for dust particle counters

Cleanliness level determination criteria: ISO14644 FS209E, new version GMP (dynamic/static)

Calibration Specification: JJF-1190-2008

Instrument features:

1. Android version 7.1 provides a better user experience.

2. Built in temperature and humidity sensor, environmental pressure sensor

3. The core component of the light scattering sensor significantly eliminates stray light in the cavity, greatly improving the signal-to-noise ratio. This makes the measurement more accurate and reliable.

4. Calculated at a 95% confidence level (UCL), the counting results can be converted into m3 and ft3

5. According to the classification and regulations of purification levels, the purification level is automatically determined, which is convenient to use.

6. Support WiFi transmission, data can be uploaded wirelessly; At the same time, it supports copying data from USB flash drives without driver insertion and removal.

7. Configure a regulatory platform, and the test results can be directly transmitted wirelessly to the platform for long-term and short-term analysis of cleanliness, assisting in management.

8. Equipped with a new generation high-speed thermal printer, the desired particle size channel can be selected for flexible printing of results.

9. AC/DC dual-use, built-in rechargeable lithium battery, environmentally friendly and durable, can support continuous sampling for more than 6 hours.

10. Convenient and simple telescopic pan tilt bracket, making installation and sampling operations more convenient.
