Overview
LD-5L laser dust meter is JDHS brand light scattering fast dust meter, using laser micro-Illuminant technology, can directly read particulate matter (PM) mass concentration, 1 minute results or arbitrarily set Sampling time. Built-in filter membrane sampling device can collect particulate matter (PM) for composition analysis while monitoring dust concentration, and has self-calibration system, air curtain Shielding and clean gas self-cleaning functions to ensure that the Optical inspection system is not contaminated. The instrument supports software automatic zeroing and computer two-way communication, suitable for continuous monitoring of particulate matter (PM) concentration, timing sampling and over-standard alarm, equipped with a variety of cutters to choose from, and has obtained China Manufacturing Measurement Instrument License and Type Approval Certificate.

Principle
The laser scattering dust meter uses the laser beam of light to illuminate the dust-containing airflow, so that the beam of light produces scattered light, and the higher the dust concentration, the greater the intensity of the scattered light, thereby measuring the dust concentration. The method has the advantages of rapidity, sensitivity, good Stability, easy operation, high Sensitivity and small sample volume, can shorten the sampling and Analysis time, no sample storage, and reduce the error factor.
Applications
Public place monitoring, atmospheric environment monitoring, labor health monitoring, central air conditioning exhaust port testing
Standards
People's Republic of China Manufacturing Measurement Instrument License, Measurement Instrument Type Approval Certificate
Steps
1. Select PM10, PM5, PM2.5, PM1.0 or TSP cutters as required
2. Set Sampling time (standard 1 minute, 0.1 minute or manual transmission can be set)
3. Turn on the instrument for measurement and read the dust mass concentration directly
4. Communication interface for data processing and printing
5. Set Alarm threshold to achieve concentration alarm function
Notice
• The instrument has a built-in filtrating device and needs regular maintenance to avoid dust affecting the life of the parts
• Ensure that the battery is sufficient before use, can be used continuously for 8 hours, with Power Adapter backup
• Pay attention to the LCD Chinese character menu prompts during operation to ensure that the parameters are set correctly
• Optical inspection system to avoid contamination, using air curtain Shielding and self-cleaning function to keep clean
• Storage data can be cycled through 99 groups to back up important information in time
Measurement time, shutdown time, arm-up time and sampling times must be within the allowable range
