The Mechanical Equivalent of Heat ('J' apparatus) is an old unit patterned on the old Griffin model in the UK where mechanical work done is converted to heat and compared with the electrical equivalent. IEC has made a superb, unique and low cost digital model of extreme accuracy but only up to sample level. Design and production development cannot occur unless there is a proven market. The HL3800-001 performs quite well and permits both electrical and mechanical friction heating of a solid copper calorimeter. Temperature measurement is by thermometer.
