The Lufft CHM8k ceilometer is a simple, one-wavelength backscatter LiDAR. Within its operating range of up to 8 kilometers it reliably detects multiple cloud layers, cloud bases and cloud penetration depths. Excellent signal performance is achieved by a stable wavelength, narrow line width microchip. It allows an efficient daylight suppression and minimised temperature fluctuations. The used pulse energy and frequency of the laser results in a eye-safe operating mode and an instrument classification as laser class 1M product. The CH8k’s user-friendly design and easy handling, makes it ideal for unattended and continuous operation. Either being used as sophisticated aerosol research instrument or being integrated in a larger networking operation, the CHM 8k is a state-of-the-art solution for today´s manifold requirements for atmospheric research.
