Calorimetric standard

= k·  T core

- D w,Co

core = water  - D w,Co = c w ·  T water

·1/(1-h) ·  c i

- c w = specific heat capacity of water = 4181 Jkg -1 ºC -1 (1 cal kg -1 ºC -1 ) - h = thermal defect: part of absorbed energy not leading to  T water (chemical reactions, heat leakage, ..) -  c i = other “technical” factors derived from measurements or calculations

thermistor :  R/R = 0.0009% / Gy  T water  0.00024 ºC / Gy thermistor :  R/R  3.7% / ºC
