THE LOW-TEMPERATURE FURNACE
The low-temperature furnace for realisation of metal freezing points is based on the design of Chattle (p.65,
"Supplementary Information for the International Temperature Scale of 1990," B.I.P.M., 1990). It is
furnished with two independent control systems, one for temperature control using a PRT and the other for
over-temperature protection using a type N Thermocouple.
INTRODUCTION
The Isotech Low Temperature Fixed Point Furnace is designed specifically to realize and maintain the
freeze plateaux of Isotech Indium, Tin and Zinc Fixed Point Cells, for calibration of thermometers on the
International Temperature Scale of 1990.
The Low Temperature Furnace is a single-zone furnace. The recommended procedure for establishing a
freeze plateau requires operator attention until the plateau is realized. Following that, the Model 17701
Furnace will maintain the plateau, essentially automatically, for a period of 10 to 12 hours.
The furnace core, into which the freeze-point cell is inserted, is of Aluminium alloy, which provides a very
low thermal gradient along the core length. The main furnace heater is of the parallel-tube design as used
at NIST. A pre-warming tube is provided.
Two entirely independent over-temperature safety devices are included. A dedicated (on-off) over
temperature control circuit provides active safety. A fusible link in the main power circuit provides passive
safety.
The Low Temperature Furnace is completely self-contained, castor mounted and requires no external
supplies (except power).
NEW FEATURES
The furnace has been upgraded to benefit from the latest technology. Fitted with a crystal clear colour
display the furnace is now fully programmable. Programs can be created for the furnace to switch between
set temperatures, for example to bring the furnace to the melt or freeze temperature at a desired time, or to
lower the furnace temperature after a predetermined time.
The PID control parameters are now dynamically optimised at different temperatures optimizing furnace
stability. An Ethernet interface allows the furnace temperature to be monitored across a network whilst a
USB Interface allows programs to be copied or for the furnace heat up and cool down history to be
exported.

QUICK START
Locate the furnace in a suitable, level location. Leave a minimum of 150mm of space around and 500mm
above the furnace for air circulation. Ensure there is a suitable power supply nearby.
Assemble the furnace as in figure 18, connect the furnace to the electrical supply and power it up.
The Overtemperature controller will power up and display the current temperature of the furnace.
To power up the furnace you will need to enable the main controller. To do this, press the SCROLL button
on the Overtemperature controller until Hi Alarm is displayed, using the up/down buttons enter a new
temperature for the overtemperature protection.
Initially this can be quite a low value, say 200°C, for test purposes. Now press the SCROLL and PAGE
buttons together, once to enter the new value and a second time to reset the controller. On the second
press the furnace will make a noise as the main control circuit powers up.
The furnace is now active and ready for use. On the main controller, press the SCROLL button to highlight
the Setpoint box. Press again to adjust the value and select a suitable value, a value 20°C below the
overtemperature is suitable, using the up/down buttons. Enter the value by pressing the Scroll button. The
furnace will now rise in temperature to the selected value.
If the furnace has been in transit or not been used for several days then there may be an ingress of
moisture into the insulation and other ceramics, the furnace may need to be “dried out” by running at a low
value such as 100°C for a period of several hours.

condition. If the furnace goes into the alarm condition, it will power down the Main controller and circuitry.
Adjusting the Overtemperature value on the controller:
1. Press the Scroll button to display A1 HI
2. Use the up/down buttons to scroll to the desired alarm setting. This would normally be 10-20°C
above the target temperature
3. To enter the value, you will need to press the PAGE and SCROLL buttons simultaneously
4. To re-set the controller from an alarm condition you will need to press the buttons again
simultaneously
5. If the controller is in the alarm condition and the complete furnace is powered down, the controller
will “remember” the condition and will still need to be manually reset when powered up again
