Mechanical Equivalent of Heat J Apparatus with Electric Heater pH Rod Time Accuracy Standard: +/- 60The Mechanical Equivalent of Heat ('J' apparatus) is a traditional unit based on the Griffin model in the UK. It measures the conversion of mechanical work into heat and compares it to the electrical equivalent. This is an affordable, digital version, but it is only suitable for sample level use. This apparatus allows for both electrical and mechanical heating of a solid copper calorimeter through friction. Temperature is measured through the use of a
