Enabling modern urban and industrial operations through outstanding pollutant and weather awareness.
Air pollution and urban emissions are critical factors to any urban or industrial air quality program. Fortunately, modern ceilometer technology is rapidly expanding the range of insights available to planners, officials, and companies. CL31 and CL51 are leading the way as the most trusted, reliable ceilometers in the industry.
Both ceilometer models provide crucial insights and enable more proactive, informed operations:
Capture accurate, reliable cloud base height, and vertical visibility data on multiple cloud layers to 25,000 feet (7.6 km).
See technical data for this compact and lightweight instrument for cloud base height and vertical visibility measurements.
Explore high-range cirrus cloud height detection with a range up to 15 km (49,200 ft).
