The LIDAR-based cloud height sensor / ceilometer CHM8k is prepared to work throughout the year and in any  climate.

The CHM8k is the latest ceilometer from Lufft. Using the LIDAR technique, it detects backscatter aerosol profiles/structure in multiple layers, cloud bases, cloud penetration depths as well as vertical visibility and issues the sky condition index. It has an operating range of up to 10 km (32,800 ft) and is equipped with an integrated controller offering a fully embedded real-time calculation of all target parameters and comfortable user interfaces. The Lufft ceilometer series is prepared to work throughout  the year and in any climate. Due to their double case structure combined with a window blower and an automatic heating system, the ceilometers are free of fogging, precipitation, freezing or overheating issues.
