Lufft - Model CHM 15k -Ceilometer, 0 - 9.32 mi Range, 230 VAC
The CHM15k ceilometer measures aerosol backscatter profiles and cloud bases up to 15 km height. The unit has a solid state laser integrated and operates at 1064 nm, a wavelength where water absorption is not an issue. The detection unit is measuring in photoncounting mode. The CHM15k belongs to an instrument class, which are also called micro pulse lidars (MPL). It is mainly used in the science market operated by met services, environmental agencies and research institutes. The CHM15k is used whenever the whole tropheric range is of interest." This particular model is designed for a 230 VAC power connection.
Strong signal quality
The sensor achieves excellent signal quality thanks to its stable wavelength and its Nd:YAG narrow-beam microchip laser operating in the 1064 nm range. In addition, its technology enables efficient daylight suppression and reduces temperature fluctuations to a minimum.
Continuous operation
The CHM 15k features a user-friendly design that enables unattended, continuous operation.
Multi-purpose
It is suitable both as a sophisticated aerosol research instrument and as part of a large measurement network.
