This may well have been covered before, especially with me being a new user, so feel free to point the direction of an old thread.
What I'd like to know is your product recommendation for the best/simplest way to measure compressor run time hours for a commercial walk-in freezer over 2 weeks?
At this stage I'm considering a HOBO state logger connected to a clamp-on current switch or maybe one of those small magnetic field motor on/off recorders.
Any advice from those that have been there before?
