ZDM100 Disdrometer is a laser instrument that measures the drop size distribution falling hydrometeors. It can also monitor rainfall types, visibility, radar reflectivity and other parameters. It is widely used in the field of hydrometeorology.
Based on the principle of optical laser active detection, the disdrometer can continuously observe the raindrops definition size, velocity and quantity of raindrops

What Is Disdrometer?
A disdrometer is a laser instrument that measures the drop size distribution falling hydrometeors.
What Can A Disdrometer Measure?
What A Disdrometer Can Be Used For?
Can A Disdrometer Replace A Rain Gauge?
No.Their positioning is different. Conventional Tipping rain gauges are mainly used as wmo-approved main rainfall observation equipments, mainly used in the meteorological station system.
The disdrometer is a professional analytical instrument, mainly for scientific research users, independent deployment of the field.
Can A Disdrometer Replace a Visibility Sensor?
Disdrometer can monitor horizontal visibility information, but it is only a subsidiary function, and its monitoring range is small, so it can not replace professional visibility sensor.
