Lufft CHM 15k Ceilometer, 0 - 15 km Range, 115 VAC

Lufft CHM 15k Ceilometer, 0 - 15 km Range, 115 VAC
Product #: 8350.10
Brand: LUFFT
Unit Price Contact Hach

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.
