Application Scope
The TH-2012 forward scattering visibility instrument can be widely used to measure meteorological visibility distance in heavy fog, rain, and snow weather ranging from 10 meters to 50,000 meters. It can be used alone or in combination with automatic weather stations, mainly applied in meteorological stations, ships, highways, and other transportation departments.
Instrument Features
•The instrument is based on the forward scattering principle of light, with extinction treatment inside the core optical unit to prevent secondary stray light interference, the instrument has stable long-term measurement performance, controlled by microcomputer processor, can continuously monitor atmospheric visibility, real-time output and store data;
•Output rate: 30-300 seconds optional;
•Rainfall measurement, minimum measurable rainfall 0.15mm/h, maximum rainfall 250mm/h, accuracy ≤10%;
•High integration, low power consumption, suitable for various applications including long-term continuous monitoring in harsh outdoor environments;
•By emitting infrared light pulses and measuring the forward scattered light intensity of suspended particles in the atmosphere, appropriate algorithms convert measurement values to atmospheric visibility values, and maintain reliable measurement accuracy in mixed complex weather with intermittent return signals (such as rainfall and hail).
