Dual Furnace Models M17705, N17706 & 17707 Iss.09 – 12/14
SPECIFICATION
Dimensions of the cabinet containing the apparatus are:
Width:
600mm
Depth:
560mm
Height:
960mm (excluding thermometer storage rack)
Control:
The heat-pipe and the annealing furnace are controlled independently to a resolution of
0.1°C.
Communications:
RS422
Temperature range:
120°C to 250°C.
Over-temperature
Provided on each furnace and operated by an independent sensor.
protection:
Supply:
2kW, 220-240V, 50/60Hz.
(110-120V to special order)
Performance:
Essentially temperature-gradient-free heat-pipes provide the ideal apparatus for fixed point
calibration and give a virtually perfect freezing profile within the fixed point cell.
The addition of the second furnace enables thermometers to be stabilised before calibration,
by annealing out strain and removing any 3D oxides.
A comprehensive manual accompanies each apparatus.
Reproducibility of the temperatures of freezing indium or tin is typically ±0.1mK with Isotech fixed point cells.
HOW TO ORDER
Ask for Model 17707. We need to know your voltage and whether you require communications. A temperature
equalising block is an available option (for comparison calibration purposes).
PLEASE NOTE: You may wish to purchase cells and thermometers with this apparatus. Both are available from
Isotech. Next Generation Apparatus is also available for Zinc, Aluminium Silver and Copper fixed points. Please ask
for data sheets 17705 and 17706.
