The current version 6.2.22101.05 of the licence-free KELLER software «KOLIBRI Desktop» now supports all functions of the replaced KELLER software «Logger 5». For example, device calibration of data loggers via zeroing is now possible with «KOLIBRI Desktop». «KOLIBRI Desktop» is continually being improved and equipped with new functions; the most up-to-date version is always available on the KELLER website.

The development of the Logger 5 software has been discontinued and KELLER no longer offers technical support. However, the software continues to function.
