First introduced to assist in relation to the SARS outbreak during the early 2000s the Model 988 is now helping in relation to coronavirus. It can be used to increase the accuracy of thermal imagers being used to measure human skin temperature in temperature screening of applications. It can also be used to check non-contact clinical thermometers.

This blackbody meets the demand for a simple, cost effective but high accuracy calibrator for the calibration of thermal imagers and infrared thermometers used at temperatures around human body temperature.

A 70 mm diameter ridged plate is heated or cooled with an internal solid state thermoelectric heat pump. The temperature of the plate can be set from 20°C to 45°C to a resolution of 0.1°C.

The standard version has a 210mm long tube mainly used with thermal imagers. A second version has a 40mm tube more suited for checking medical thermometers.
