Class Joulemeter: Mk II by Unilab

Energy Measurement is made simple with the Class Joulemeter (MkII) by Unilab.

Connects between power supply and load
LED Indicator gives one flash per 100J
Calculate specific heat capacity
Accepts 9 to 16V a.c. or d.c.
Ideal for use with calorimeter blocks

Although it can drive loads up to 10A, ideally it is best used with loads requiring between 0.4 and 4A when accuracy is ±5%.
Associated Products include:

Immersion Heater – B8A42584
Calorimeter Blocks – B8H25432, B8H25456, B8H25444
Bench Power Supply – B8G85458
Learning Outcomes
Key Stage 3 Physics – Energy: Comparing power ratings of appliances in watts (W, kW). Comparing amounts of energy transferred (J, kJ, kW hour)
Key Stage 4 Physics – Electricity: Power transfer related to p. d. and current, or current and resistance.
Key Stage 4 Physics – Energy: Power as the rate of transfer of energy.
Key Stage 4 Physics: Calculating energy changes involved on heating, using specific heat capacity; and those involved in changes of state, using specific latent heat
