Bench-mounted primary standard Calibration Source
LANDCAL P1200B is a bench mounted, primary standard, variable temperature source designed for testing and precise calibration of most industrial radiation thermometers, thermographic equipment and thermocouples.
The LANDCAL P1200B is a bench mounted, primary temperature source designed for testing and precise calibration of most infrared radiation thermometers at temperatures up to 1150 °C. The isothermal enclosure provides a highly stable, uniform temperature along the length of the cavity, which is also suitable for the calibration of thermographic instruments and also the calibration of thermocouples by the comparison method.
The large diameter, conical ended, blackbody cavity is heated by three separate, independently controlled electrical windings which can be adjusted to minimise thermal gradients. The temperature of the cavity is measured using an optional rare metal thermocouple supplied complete with traceable calibration certificate. A second optional rare metalthermocouple can also be supplied to determine thermal gradients.
