Gemini R 976 Blackbody Calibrator.
Gemini R 976 Blackbody Calibrator radiation source.
Calibration of Radiation Pyrometers: 50°C to 550°C
The Gemini R is a blackbody calibrator source with which radiation pyrometers, commonly referred to as
IR sensors, can be calibrated.
With a temperature range of 50°C to 550°C, the temperature of the cavity can be set with 0.1°C resolution.
The temperature of the furnace is set and indicated on a PID controller.
An independent indicator is also
provided for higher accuracy with a standard probe, which indicates the actual radiance temperature.
Temperature variation over a 5-minute period, as viewed on the temperature controller, is ±
0.2°C and
a radiation thermometer directed into the cavity detects similar variations.

R 976 | Gemini R 976 Blackbody Calibrator radiation source. |
Maximum temperature differences are ±1°C in the range of 100°C to 500°C.
The Gemini R is capable of accepting blackbody fixed points to achieve the highest level of a radiation
measurement possible.
Typical fixed-point uncertainties are ±0.25°C. Gallium, indium, tin and zinc cells are available.
for the built-in indicator and/or supplied probe.
The Gemini R can be supplied with RS232 or RS422 communications.
