The mains Joulemeter / Wattmeter is accurate, light and compact. It is designed for class demonstration and also for student use. The meter measures the energy or power delivered to a mains appliance.Current transformers and sampling voltage transformer isolate the unit from the mains. Determines the energy consumed by domestic appliance. Compare the efficiency of different types of lamp bulbs. Compare power consumption for lamp bulbs at different voltages (variable mains transformer unit required) Analogue outputs for datalogger or oscilloscope. Built in timing function. ( 614-007 )
