2.2 Structure
Temperature dry well calibrators consist of an electrically heated
metal block and a control unit. The two components are
accommodated in a robust metal housing together with a fan. The
metal block is fitted with a bore in its centre for holding the
adapting sleeve. This adapting sleeve contains one or several bores
of different diameters for thermically coupling thermometers of
various thicknesses optimally to the heated metal block. Good
thermal coupling between the block, the adapting sleeve and the
thermometer is very important for keeping measuring uncertainty
during calibration to a minimum.

2.1 Intended Use
2. Device Description
The calibrators of the CTD 9300 series may be used exclusively for
the calibration and verification of thermocouples, resistance
thermometers, mechanical thermometers and temperature
switches.
The introduction of foreign substances such as oil or heat
conductive paste with the aim of enhancing the heat transfer to the
probe can damage the calibrator and the adapting sleeve.
In addition, there is a risk of injury due to abruptly evaporating
fluids and hazardous gases that may form when fluids evaporate.
Always ensure that the testing temperature is not too high for the
probe. Otherwise, the probe may be destroyed.
Remove all highly combustible media from the vicinity of the
device and ensure that the device cannot come into contact
with easily inflammable or explosive media.
