Overview
LD-1H dust detector is a new generation of environment monitoring instrument developed and produced by JDHS. It adopts laser light scattering method for direct reading measurement, which can quickly measure the concentration of PM2.5, PM10 and TSP in the air in real time. The instrument has the advantages of fast Measurement speed, high Sensitivity, Good Stability, light weight, low noise, simple operation, AC and DC dual-use, etc. It can be portable fixed-point monitoring or multi-station point interconnection and data aggregation through the network, and has strong practicability.
Features
1. Large-screen LCD Chinese display with blue backlight, easy to operate and convenient for night application
2, built-in real-time clock, measurement data with time storage, easy to statistics and analysis
3. Simultaneous measurement of PM10 and PM2.5
4. Sampling time can be set freely within 0~ 9999 seconds
5, with continuous measurement and General Measurement mode, support unattended continuous measurement
6, large data storage capacity: general measurement can store 20 sets of data, continuous measurement can store 8000 sets of data
7. Data can be transmitted in various ways, such as wired or wireless, and can be exported to a computer through the output interface
8. Power Supply for Built-in Battery and External Power Adapter, AC/DC dual-use
Principle
The instrument uses the principle of laser dynamic scattering for measurement, and directly reads the particulate matter (PM) concentration in the air through the laser light scattering method to achieve fast and sensitive detection.
Applications
Disease control center, supervision, environment monitoring, online dust monitoring at construction sites, household, office, factories and mines, scientific research institutes, public places, central air conditioning exhaust, air purifier purification efficiency evaluation
