INTRODUCTION
Th e P e gasus
Plus
1200 series consists of two models, the Basic (B) and Site (S). Both models
have been designed to be rugged and easily maintained.
By using a proprietary plug-in controller the total electronics package can be replaced in a few
minutes. As can be seen from the parts list, remarkably few components have been used, each
o f wh i ch are easily removed and replaced. All models have a temperature range of 150 to
1200 C.

1200 B - see page 33
This model p ro vides an isothermal enclosure (metal block) in which thermometers and
thermostats can be checked against the temperature indicated on the temperature controller.
For traceable calibration a standard (reference) probe should be placed into the metal b l ocks
alongside the units under test.
The probe under test should be calibrated by comparison to the standard probe.

1200 S - see page 34
The S is again similar to the B but this unit has the addition of a digital temperature indicator. The
indicator is independent from the controller and can be programmed to work with a thermocouple
or industrial Pt 100 resistance thermometer.
T h i s combination of sensor and probe can be calibrated. Then the units under test ca n b e
compared to the independent calibrated measuring systems allowing for traceable calibration.
The Pegasus
Plus
1200 Series represents the third generation of a ten year development program.
During which many customer improvement suggestions have been incorporated into the models.
S uch suggestions have generally arisen from technical queries posed by equipmen t u se rs,
