Thies laser raindrop spectrometer
Product details

Typical applications:

Meteorological Science Research
High water level warning
Agricultural meteorology and hydrology
Airport and highway traffic monitoring
Hail suppression and artificial rainfall monitoring
Radar calibration
The most advanced technology and the best cost-effectiveness
Accurate detection of rainfall and snowfall processes, detailed analysis of rainfall and snowfall characteristics
The laser raindrop spectrometer can monitor and distinguish between drizzle, heavy rain, hail, snowflakes, snowballs, and various precipitation between snowflakes and hail falling. It can calculate the intensity, total amount, and visibility of various types of rainfall, conduct necessary analysis, draw raindrop spectra, and calibrate meteorological radar data.
Instrument principle:
Applying laser principle (785 nm laser) to measure high-speed moving objects. Can measure the total amount, size, intensity, and speed of moving objects. Its superior performance is particularly demonstrated in the measurement of small objects, with a minimum diameter of 0.16 mm for the measured object.

ThiesSpecial considerations for installation and use

1)Ensure correct, stable, and waterproof wiring when installing power and communication cables;

2)The waterproof ring of the main box is installed correctly to ensure waterproofing;

3)It is best to install it on grass (or without dark stones, asphalt, etc.), otherwise it will generate upward airflow and form stripes under strong sunlight radiation, which will affect the measurement;

4)Installation off the ground1.5~2mDistance, distance from other instruments1mDistance;

5)There is no vortex or strong wind at the installation site;

6)The main box should be installed facing south;

7)Connect the communication before powering on; After the power is cut off, remove the communication.

Security maintenance

1)Do not look directly at the laser beam of the instrument;

2)When aiming at the housing, the laser warning label is not clear and cannot be operated;

3)about3Monthly cleaning of window pane glass (eyeglass cloth)
