II Outline

LZJ¡ª01D particle counter is manufactured based on the light scattering theory of particles. Light will be scattered on particle surface when the light beam touches particles. The intensity of scattering light is related to the intensity of light source and particle size. With the same light source, particle size could be obtained by measuring the intensity of scattered light.

When the location of the light source is fixed and particles go through the light beam by the air pump, light will be scattered during the process. The intensity of light scattered is dependent on the particle size. Light will be scattered n times when particle number is n, thus n light pulses are generated. They become n pluses after the photoelectric conversion. Measurement of particle size and number is made with the light scattered on particles.

LZJ¡ª01D particle counter has a laser large-screen LCD and it is applicable for both AC and DC. It has unique features including:

1 Use of imported semiconductor laser tube and imported semiconductor photosensitive receiver;

2 The core component of the entire instrument, light scattering sensor, is the crystallization of the factory from many years of painstaking research. Its structure is unique in the country, which significantly eliminate the stray light of the cavity, and signal to noise ratio is greatly improved, so that the measurement is reliable. It has been patented in China.

3 The confidence level of the instrument was measured in accordance with the GB/T16292-1943896, which requires determining the cleanliness level automatically by two conditions. The method of cleanliness determination of this instrument is more comprehensive than other similar products in China which only use one condition. This instrument is more in line with national standard.

4 The instrument can store up to 1000 measurement data and query historical data in time.

5 The measurement data can be connected to computer for data communications (Optional).

6 Temperature and humidity can be measured simultaneously during the process of particle sampling when the temperature and humidity sensor transmitter are added with user¡¯s requirement (Optional).

7 The instrument is the unique one in China which shows the sampling air volume with digital displayer, and it is more intuitive and accurate.

4 Field measurement: normal monitoring (randomly), certified monitoring (UCL)

(1) normal monitoring (randomly)

A.   After warm-up for 3-10 minutes, parameters such as date, time, cycle, continuous sampling times can be set and choose the right numbers with the ¡°Enter¡± button.

Fig. 3 Display the measurement information on screen

B.   Choose the sampling location and place the instrument in the right place. After the measurement tripod support is positioned, remove the sampling tube from the back and connect to the sampling probe.

C.  Press ¡°Test¡± button and the sampling starts after the time delayed is complete. Screen shows the information. After each test, the screen shows the measured result for each particle size. If the ¡°Observe¡± button is pressed, the change of particle number with the time can be seen. The environment is dirty when it changes rapidly, and vice versa.

(2)  certified monitoring (UCL)

A.   Turn on the power and press ¡°reset¡± button. Set the sampling point number, sampling times, sampling interval and time delayed; Please refer to JGJ71-90 (when the sampling points are more than 9, cleanness will be determined without UCL);

B.    Procedure: Click the ¡°Confidence level¡± button. When the sampling process finished on the first point, the instrument will generate the beep sound. Then the instrument can be moved to the second sampling point and at the same time it will go into the countdown process of ¡°sampling interval¡± automatically. When the instrument is located on the second sampling point and the countdown process is close to the end, the instrument will enter the countdown process within the ¡°time delayed¡±. After the countdown process is complete, sampling on the second point begins. After the completion of the second point sampling, the same procedure is applied on next points until the cleanness level is calculated and determined.
