Temperature calibrator and method for regulating the temperature of a temperature calibrator

摘要

The present invention relates to a temperature calibrator and a method for cooling and heating the kalbriervolumens of a temperature calibrator. The temperature calibrator comprises at least one to tempering calibration volume, at least one heat source and at least one heat sink, at least one temperature sensor and at least one electrical control unit, wherein the heat source comprises at least one resistance heater and the heat sink at least one peltier - element comprises. For the gentle operation, the peltier block - element with a substantially constant current is applied and, at the same time, the resistance heater with a varying current is applied.
