Digital Joulemeter and Wattmeter
Product Code : JA-M-7831
The Digital Joulemeter and Wattmeter (SKU JA-M-7831) is a bench instrument that measures the electrical energy delivered to a load or the power it is drawing, on a large red 4-digit display. This digital joulemeter and wattmeter switches between accumulated energy and instantaneous power with a toggle switch, accepts inputs up to 24 V DC and has ranges from 1 mJ to 100 J per digit. JaincoLab manufactures it in India for school and college physics laboratories.
Specifications
The instrument has a large red 4-digit display that shows either accumulated energy or instantaneous power, selected by a toggle switch, a maximum input of 24 V DC and ranges from 1 mJ to 100 J per digit.

Applications of the digital joulemeter and wattmeter
In physics practicals the meter is placed between a low-voltage supply and a heater, lamp or motor so that students read directly how much electrical energy has been supplied, or how much power is being used, without calculating it from separate voltage, current and time readings.
- Measuring the energy supplied by an immersion heater in specific heat capacity experiments
- Specific latent heat experiments using an electrical heater
- Measuring the power of lamps, heaters and small motors on low-voltage DC
- Finding the efficiency of a motor lifting a load
- Comparing energy use of different components in a circuit
