Joulemeter / Wattmeter, Digital Manufacturer,Supplier and Exporter in India

The Joulemeter/Wattmeter is light, compact, and designed for class demonstration or student use. 
The unit can measure energy taken up by a load, either by AC power or DC power, and from 1J to 999,999J or 1mJ to 999,999mJ and can also measure power level of 200mW to 200W. 
Depending on mW / mJ or W / J range, 1V full scale deflection represents 100mW or 100W respectively.
One pair of 4mm sockets is also provided to indicate the instantaneous power.
