The 8339 Laser Ceilometer measures cloud height and thickness, in addition to vertical visibility, detecting up to four cloud layers simultaneously to a distance of 25,000 vertical feet.
Accurate measurement of cloud height and thickness in all weather conditions, including heavy precipitation and low clouds, can cause serious errors in other ceilometers. Proprietary algorithms and digital techniques from 20 years of research allow the 8339 ceilometer to provide accurate information even in difficult circumstances.
Sensing circuits and optimization algorithms control the pulse frequency, output power and temperature of the laser itself in order to dramatically extend its life. In addition, the 8339 is enclosed in a NEMA 4X stainless steel package that will stand up to the harshest environmental conditions thrown at it. From corrosive marine air to blowing desert sand, the 8339 is designed to last.
