- Model R1500T - High Temperature Transport



High Temp. Transportable blackbody reference source. LANDCAL R1500T is a high temperature, transportable blackbody radiation source designed for calibration of a range of thermometers such as System 4 and Fibroptic thermometers. R1500T is a reference standard source giving a resolution of ±1°C/2°F.

The LANDCAL R1500T is a high stability, transportable, blackbody, reference source designed for on-site or laboratory calibration of infrared radiation thermometers up to temperatures of 1500 °C/2750 °F.

Six silicon carbide elements heat the conical ended cylindrical blackbody cavity to 1450 °C/2650 °F in approximately 30 minutes. A 3-term controller holds the set temperature to within ±1K/2°F.

The R1500T can be used as a transfer standard, providing calibration by the comparison method, using optional standard radiation thermometers. Alternatively a traceable calibration certificate can be supplied for the source, as an optional extra, where direct traceability is required.
