I. Overview:

The laser large-screen liquid crystal display type CLJ-C dust particle counter has unique characteristics and is the most advanced product in the same domestic product.

1, using imported semiconductor laser tube and imported semiconductor photosensitive receiver.
2. The core components of the whole instrument, the light scattering sensor, is the crystallization of many years of arduous research of this factory, its structure is unique in the country, it obviously eliminates the stray light of the cavity, the signal to noise ratio is greatly improved. This makes the measurement more accurate and reliable.
3. Confidence measurement of this instrument will automatically judge the purification level in accordance with the two conditions specified in GB/T 16292-1943896.

 
The two conditions specified are:
1. The average particle concentration at each sampling point must be lower than or equal to the specified level limit, ie Ai≤ the boundary of the sector
2. The 95% confidence upper limit of the average value of the mean particle concentration of all sampling points must be lower than or equal to the specified level limit, ie UCL ≤ the boundary of the sector
3. the instrument can store 300 measurement data and can query historical data at any time.
4. measurement data can be connected with the computer communication.
5. according to the needs of users add temperature and humidity sensor transmitter for temperature and humidity measurements.
6. The instrument is currently the only instrument that can display the air sampling quantity with a digital display. It is more intuitive and accurate.

 
Second technical indicators:
According to JJG547-88 dust particle counter verification requirements.
1. self-purification time ≤ 20min;
2. particle size distribution repeatability ≤ ± 10%
3. particle size distribution accuracy ≤ ± 30%;
4.monodisperse particle dispersion ≤ ± 30%
5.sampling flow 2.83L/min ± 5%;
6. the whole insulation resistance (normal atmosphere) 50MΩ
 

Three conditions of use:
1. The maximum dust particle concentration is 4≤×10K/L
2. normal atmospheric conditions, no strong magnetic field interference around
3. power supply A.C220V±5% 50HZ
