Overview
LD-5S laser dust meter is a new generation of laser particulate matter (PM) online monitor product newly developed by JDHS to effectively eliminate Humidity interference. Portable design is small and easy to carry, and can be equipped with an optional tripod for field measurement. It has Humidity continuous automatic correction function, which can effectively reduce Humidity interference and achieve High Accuracy, High Sensitivity, Wide Range and compatibility with TSP, PM10, PM5, PM2.5, PM1.0 particle cutters.
Features
1. Humidity continuous automatic correction function
2, with a filter sampling unit, to achieve continuous monitoring of particulate matter (PM) concentration and filter sampling compatible
3. Cutting particle size: PM10, PM5, PM2.5, PM1 and TSP compatible
4. Measurement range: 0.001-100mg/m ³
5, repeatability error +/- 2%
6, can be connected to wireless transmission equipment, with a central station computer and special software to achieve long-term continuous online monitoring of particulate matter (PM)
7, optional tripod, easy to use for field measurement
Principle
The instrument has a built-in φ 40mm filter membrane sampling device, which can collect particulate matter (PM) samples while continuous monitoring, and has data processing, storage, timing sampling and dust excess alarm functions.
Applications
Labor, industrial and mining enterprises, public places, indoor air mass testing
