The Isotech Model 988 Black Body Source

The Isotech Model 988 Black Body Source

The Isotech model 988 Black Body Source was introduced to meet the demand for a simple, cost effective, but highly accurate calibrator for calibrating thermal imagers and infrared thermometers used at temperatures around that of the human body.

Unlike heat only devices, this model uses a solid state thermoelectric heat pump so that the block can be both cooled and heated. This brings two benefits, the blackbody can maintain temperature in high ambient temperature conditions and it can also operate below the ambient temperature.

The Isotech 988 features a high emissivity ridged plate that is 70mm diameter. The temperature of the plate can be set from 20°C to 45°C, at a resolution of 0.01°C. To reduce sensitivity to air drafts and ambient temperature effects, a stainless tube is fitted in front of the plate witch evaluation showing this has advantages over an open plate design. The standard tube lenght is 210mm and there is an option of a short version, 40mm long that is particularly useful for checking medical thermometers.

For applications where the unit is used at a single fixed temperature, 38°C, the set temperature on the controller can be locked to prevent accidental change of tampering. The operating unit can be switched from Celsius to Fahrenheit.
