KMK119: Bigger battery, runs 4 firmware in same time ( dip switch)
Good for end users who already use a cable probe, they replace and use KMK119 without further software engineering.
KMK118: smaller battery, runs 1 firmware in same time, bultin torch
Good for software developers, system integrators, utilities etc. Very small and easy to use. You will see once you get few pieces
