Dual Furnace Models M17705, N17706 & 17707 Iss.09 – 12/14
INTRODUCTION
The Dual Furnace range of calibration apparatus comprises 3 models, all working on the same principle and having
the following features in common:
1. A rack for storage, at around room temperature, of up to 4 thermometers. Lined with ceramic board, the
rack will not be damaged if very hot thermometers are placed in it.
2. A furnace of diameter 50mm and depth 400mm which can be used to pre-warm or anneal up to 4
thermometers.
3. A pre-calibration pocket to install a single thermometer immediately prior to calibration or to house the
monitor thermometer between periods of use.
4. A heat-pipe furnace to create optimal conditions for an appropriate range of fixed point cells. The use of
freeze-point cells within the heat pipe is described in the manual which accompanies Isotech cells.
All 4 features are built into one cabinet, making the dual furnace a self-contained calibration facility.
Both component furnaces of the dual furnace can be fitted with communications interfaces for automated use.
