-Instrument features:
 
Ceilometer CHM15K is a simple, single-wavelength backscattered lidar. The measurement range is up to 15 kilometers, which can accurately detect multiple clouds, cirrus clouds and aerosols;
 
Excellent signal performance is achieved by stable wavelength, narrow line width microship Nd and 1064 nm YAG laser. It can effectively suppress sunlight and control temperature fluctuations to a minimum;
 
The use of energy pulses and laser frequency can ensure eye-safe operation and the laser level of the instrument is 1M;
 
Convenient design, simple operation, unattended and continuous operation can be realized;
 
Whether it is a complex aerosol research instrument or is integrated in a larger operating network, CHM15k is a state-of-the-art solution that can meet many aspects of atmospheric research.
