Unlike conventional AC hour meters that are
limited to one primary voltage andfrequency, the
Hobbs Multi-Range Quartz hour meter will
operate over a full range of voltages and
frequencies. The meters will work accurately
over a voltage range of 90 VAC to 264 VAC
and at frequencies of either 50 Hz or 60 Hz.
This unique feature means that one hour meter
will work for virtually any application anywhere
in the world!
