【Abstract】 A precision calibrating apparatus for thermometers is described. It employs high temperature sodium heat pipe as isothermal part and utilizes standard high temperature platinum RTD both as. temperature measuring and controlling devices. Consequently, the temperature control stability is better than ±0.01℃/30 min and the homogeinity of temperature distribution is greatly improved. Hence the problem of bw accuracy of temperature setting of the thermostat can thus be satisfactorily settled.更多还原
