The CHM 8k is the latest ceilometer from Lufft. Using the Lidar technique, it detects backscatter aerosol profiles 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 8000m and is equipped with an integrated controller offering a fully embedded real-time calculation of all target parameters and comfortable user interfaces. The ceilometer is prepared to work throughout the year and in any climate. Thanks to the double housing design in combination with a window fan and an automatic heating system, the Ceilometer is optimally protected against fogging, precipitation, freezing or overheating.
