Abstract

The invention relates to a device for calibrating at least one thermometer, said device comprising a block made of a thermally conductive material which is provided with several bores on a first side thereof, in which bores at least one calibration thermometer and said at least one thermometer to be calibrated can be placed, at least one temperature control element for heating or cooling the block, as well as control means for controlling the temperature control element. According to the invention, the calibration device is to that end characterised in that the device comprises a first envelope, which surrounds the block in a thermally insulating manner, and wherein the block is thermally coupled, via the first side thereof, with the at least one temperature control element.

Claims

9 AMENDED CLAIMS received by the International Bureau on 31 October 2011 (31.10.2011 )
1. A device for calibrating at least one thermometer, said device comprising
- a block made of a thermally conductive material having a first side, a second side and a circumferential side, which block is provided with several bores on said first side thereof, in which bores at least one calibration thermometer and said at least one thermometer to be calibrated can be placed,
at least one temperature control element for heating or. cooling the block, as well as
control means for controlling the temperature control element, characterised in that the device comprises a first envelope made of a thermally conductive material, which envelope surrounds the second side and the circumferential side of the block in a thermally insulating manner, and wherein the block is thermally coupled, via the first side thereof, with the at least one temperature control element.
2. A device according to claim 1 , characterised in that said at least one temperature control element is thermally coupled to the first side via the first envelope.
3. A device according to claim 1 , characterised in that the device comprises a second envelope made of a thermally conductive material, which second envelope surrounds the first envelope in a thermally insulating manner and which is thermally coupled to said at least one temperature control element.
4. A device according to claim 1 , 2 or 3, characterised in that the first and/or the second envelope are concentrically arranged around the block.
5. A device according to one or more of the preceding claims, characterised in that the block is provided with one or more thermocouples for measuring a temperature gradient between the various bores and/or in the longitudinal direction of a bore.
6. A device according to one or more of the preceding claims, characterised in that the temperature control element is provided near the first side of the block.
7. A device according to one or more of the preceding claims, 10
characterised in that the temperature control element is provided at a side of the block opposite said first side.
8. A device according to one or more of the preceding claims, characterised in that the temperature control element is a Peltier element or a heating element.
