•General

The temperature probes to be tested fit into an appropriate size reduction insert located in the 30 mm diameter hole of the dry well. The dry well can be heated by either cartridge heaters (DBC 650) or Peltier cells (DBC 150). A fan system fitted on the bottom of the instrument reduces the temperature during cooling operations.

Operating procedure

The DBC Series can be used to carry out comparison test using a variety of methods:

Reading of temperature calibration with the internal regulation probe

The generated temperature is considered as reference value and is shown on the DBC display: this temperature is measured with the standard internal probe.
