详细资料见英文：The Hyperion R Calibration Bath comprises a blackbody cavity for calibration of radiation
pyrometers. An important factor is that its operation range includes ambient temperature.
The temperature of the cavity can be set to within 0.1°C at any point from -10°C to +80°C.
This elegant, modern-styled range has been designed to work from a series of Peltier modules,
which can be used either to heat or to cool a metal block. In conjunction with a specially
programmed microprocessor-based controller it offers a unique concept in calibration sources.
With this bath, a temperature above, below or at ambient temperature can be set and this
temperature will be maintained whether the source needs to be cooled or heated.

Annealing Furnace, model 414, is designed to heat, anneal and cool SPRT’s (Standard Platinum
Resistance Thermometers) prior to calibration. The temperature range of the Furnace - from ambient to
1000ºC enables all types of SPRT’s to be annealed.
One of the duties of a calibration laboratory manager is to ensure that the SPRT’s used in the Laboratory
are fully annealed and still within specification.
Just using the thermometers within the laboratory will cause work-hardening to take place within the
platinum coil of the SPRT.
Therefore regular annealing is required to ensure the SPRT’s are in an ideal condition.
In 1990 the new temperature scale ITS-90 specified the use of SPRT’s up to the Silver point (961.78ºC). At
these temperatures quartz is very porous and in reducing atmospheres the SPRT’s can quickly become
contaminated.
The Isotech Annealing Furnace offers a safe solution for those who wish to anneal SPRT’s up to 1000ºC.
To prevent contamination at high temperatures a constant flux of pre-heated air passes the SPRT’s being
annealed.
A comprehensive handbook accompanies the Furnace.
This Furnace is installed simply and requires no maintenance
