AT-21 Transmissometer

PURPOSE
Meteorological optical range measurement. The principle of operation is to measure the transmittance of the atmospheric layer between the transmitter and the receiver Measurement of radiation intensity scattered in the atmosphere
APPLICATION
Meteorology Airfields
ADVANTAGES
The measurements are performed during daytime and at night independently and as a part of weather station, including automatic airport weather stations Possibility to simulate sensor messages from other manufacturers with console customization Contamination of the protective glass of the instrument's optical units is taken into account Automatic adjustment On-site self-test Offline software
