◆ Based on the principle of forward scattering of light, the instrument is used to eliminate the light inside the core optical unit,
◆ The instrument is stable in long-term measurement and controlled by microcomputer processor,
◆ It can continuously monitor the atmospheric visibility and output the stored data in real time;
◆ Output speed: 30-300 seconds optional;
◆ The minimum and maximum rainfall can be measured as 0.15mm/h and 250mm / h respectively, with accuracy ≤ 10%;
◆ With high integration and low power consumption, it is suitable for various applications, including long-term continuous monitoring in harsh outdoor environment;
◆ By sending out infrared light pulses and measuring the forward scattering light intensity of suspended particles in the atmosphere, appropriate algorithm is adopted
◆ When the measured value is converted into the atmospheric visibility value, it has reliable measurement accuracy in the case of mixed complex weather with intermittent return signal (such as rain and hail).

Th-2012 forward scattering visibility meter can be widely used to measure the meteorological visibility distance in fog, rain and snow weather from 10 meters to 50000 meters. It can be used alone or in combination with automatic weather stations. It is mainly used in weather stations, ships, highways and other transportation departments.
