product description
The Lufft CHM15k simulator simulates the cloud height for the ceilometer CHM 15k in order to check its measurement accuracy.
- one of the five LEDs receives the laser impulse emitted by the CHM 15k and, after a certain time has passed, sends an optical signal back to the ceilometer simulating it via the 4 other LEDs
- the time span between receiving and sending the signal as well as the time of flight of the return signal going back to the ceilometer shall correlate with a signal of an actual cloud
- the strength of the d.c. light / background light can be chosen in order to check how the CHM15k can manage disturbances caused by background light
