Student Digital Joulemeter

Student Digital Joulemeter is designed specifically for student use. 

Power is by means of a 9V DC mains adaptor included.

The unit can measure energy from 1 joule to 999,999 joules, with accuracy of 3%, but 1% accuracy is typical. 

 

Circuitry : Microprocessor, combined with precision voltage multiplier.

Built-in timing function, the start button starts timer and joulemeter together and at the same time starts powering up the load. 

Input voltage: 0V to 15V AC, or 0V to 21V DC (maximum).

Maximum load current : 10A AC/DC

The stop button stops the timer and joulemeter, and disconnects the input power from the load.

Display: 2 x 16 character LCD

Dimensions: 90 x 90 x33mm
