LD-5C (B) microcomputer laser dust meter PM2.5 PM10 TSP

Brief introduction:

Has the international advanced level in the new century new built-in membrane filter sampler microcomputer laser dust, in the continuous monitoring of dust concentration at the same time, can be collected particles, to analyze its composition, and the mass concentration conversion coefficient K value. Can direct reading dust mass concentration (mg/m3), PM10, PM5, PM2.5 and TSP cutters for selection. Instruments used powerful pump, to make it more suitable for long sample tube should be equipped with central air conditioning vent PM10 PM10 concentration detection.

Features:

1. Design the replaceable particle cutter, implements the PM10, PM5, PM2. 5, the TSP cutter is compatible with a variety of particle separation.

2. Online membrane filter sampler was designed and implemented the continuous monitoring of dust concentration and membrane sampling compatibility, can be analyzed by the composition of the collected particles and the mass concentration of the place conversion coefficient K value.

3. Using a laser light source, mass concentration is not affected by particle color conversion coefficient.

4. The large screen LCD display Chinese characters, Chinese characters menu prompt is realized.

5. The constant current controller is designed to ensure the sampling flow rate constant, the correct cutting curve.

6. Has a built-in optical standard ragtime, ensure that instruments and high stability.

7. Has the special protection of air curtain, to avoid the dust pollution of the core parts of optical system, to ensure equipment reliability.
