Hobbs Hour Meter Elapsed time 12 - 24 V AC or DC Run time

These Hobbs / Honeywell hour meters are the inside part - the part that does all the work! No enclosure. They fit most Hobbs meters if you want to replace them. Super handy for HVAC and other projects! 12-24 V ac or DC. little bit if tape over them and they are fine. Super nice for logging keeping track of run time on fans and motors in furnace and air handlers.
