INTRODUCTION
The IR-500 Calibrator is mainly structured by 58 mm diameter target assembly
and dry-well temperature system controlled by a microcomputer. The external
reference thermometer is a metal cone with good heat-conducting ability, on the
surface of thermometer there is a oxide film with emissivity 0.95.
The IR-500 Calibrator contains a class-A PT100 sensor with a temperature control
system and wind-cold device. The calibrator has rapid heating and cooling
functions and is switchable between °C/°F, which can be used for different
temperature unit calibrations.
The calibrator operates over a range of 50 °C to 500 °C with a temperature display
resolution of 0.1 °C.
