The Model 8340 Laser Ceilometer uses a design similar to that of the 8339 however, with the addition of a more powerful laser and state-of-the-art firmware.
– Keeping with the proven laser technology, the Model 8340 emits a laser pulse into the atmosphere and analyses back-scatter data to determine the top and bottom altitude of each cloud. In order to maintain accuracy in even the most volatile situations.
– FAA Certified models.
– Rugged, weather-proof sensors
– Accurate and reliable
– Accurately reads cloud height, density, and vertical visibility to a distance of 40,000 vertical feet.
