Saturn 877 Thermocouple Calibration Sphere.

Spherical furnace. Thermocouple Calibration furnace.

Saturn 877 Thermocouple Calibration Sphere. Temperature range 100°C to 1300°C.
The Saturn spherical furnace comprises a number of concentric shells.
The outer shell of spun metal is for containment and support. Inside this is a layer of ceramic fiber.
Within the fiber is a ceramic spherical mantle containing the heater windings.
In the center of the furnace is a solid cast ceramic sphere with 8 or 16 tubes, to be used for the thermocouples
requiring calibration.
Model 877 Saturn Spherical calibration furnace is revolutionary from a number of aspects:

It is spherical, and its design ensures a central zone of constant temperature.
Thermocouples are inserted around the circumference of the furnace.
When fully inserted the measuring junctions are within a few millimeters of each other at the center of the
sphere. Up to 15 thermocouples can be calibrated simultaneously.
The accuracy is between ±0.25°C and ±0.1°C at 1000°C.

Larger tube diameters will give larger gradients, as will larger numbers of tubes.
The precision of this furnace has previously been achieved only by using heat pipes.
Because of the design the price is only one half to one third that of a bath with comparable accuracy
and much smaller capacity of calibration.
The use of newly developed modern ceramic materials has enabled high accuracy, low mass and
high stability to be obtained.
The Saturn system will not contaminate your thermocouples unlike some furnaces that have metal
equalizing blocks.
