Y09-550 laser dust particle counter (hereinafter referred to as instrument) is used to measure the size and number of dust particles in air per unit volume in air environment. It can directly detect the clean environment with a clean level of 300,000 and 10 levels. A new generation of products developed by the new national policy and new orientation.
The instrument adopts semiconductor laser light source and touch screen (liquid crystal display) for display, reasonable structure, high detection precision, large flow rate, short sampling time, simple and clear function operation, no need for computer data acquisition, and can be directly saved in U disk and other storage media. Computer control, can store and print sampling results, built-in thermal micro-printer, test environment is very convenient.
Widely used in electronics, optics, chemistry, food, cosmetics, medical and health, biological products, aerospace and other sectors.
working principle
The instrument adopts the principle of light scattering. When the suspended particles in the air pass through the photosensitive region, the luminous flux is proportional to the particle diameter, and the equivalent diameter and quantity of the collected particles are obtained after photoelectric conversion, amplification and processing.
Precautions
1. The working position and sampling port of the instrument should be in the same air pressure and the same temperature and humidity environment, so as not to affect the normal operation of the instrument and condensation to damage the instrument. If it is necessary to work under pressure, the large differential pressure of zui cannot exceed 200Pa. Working in the presence of differential pressure and temperature and humidity will increase the measurement error and damage the instrument.
2. It is forbidden to extract gas and high temperature gas containing water vapor, oil and corrosive substances; it is forbidden to use in high dust concentration environment; avoid using the instrument in non-purifying environment.
3. When the instrument is not in use, it should be placed in a dry, dust-proof indoor environment, and should be energized for more than 30 minutes every month.
4. When carrying the instrument, it should be handled gently and with less vibration and impact. Zui is placed in a special box and moved.
5. The instrument is allowed to be transported and stored in the following environment under the condition of factory packaging: temperature: -40 ° C ~ 50 ° C humidity: 90% RH (40 ° C).
6. The instrument should be returned to the production plant for calibration once a year to ensure its accuracy.
7. If the user cannot solve the problem, please contact the production unit immediately.
