Abstract
The present invention introduces a temperature calibrator arrangement, which comprises inner and outer Peltier elements as heating and cooling elements for the calibrator block. The arrangement comprises a first and second variable current or voltage source, and, in an embodiment, a first and second mechanical relay for switching polarities of the Peltier elements. The present invention controls the first and second current sources independently of one another. Furthermore, some methods are presented for getting rid of mechanical relay switchings while using the temperature calibrator during normal use, resulting in less clicking sounds and less physical wear as well.
