Great helper to track my compressor working hours
Needed a simple hour meter for my shop air compressor. Works on 220-240V AC, fits nicely into the panel. Starts timing right when power turns on, readings stay accurate. No reset button is actually good for me, no risk of accidentally clearing runtime data. It runs steady between -10℃ to 50℃, perfect for my unheated garage. Now I can easily schedule oil changes and maintenance for the compressor.
