The IR2303 black body calibrator is specifically designed for calibrating infrared thermometers operating above ambient temperature, with a capability of handling temperatures up to 500 °C [932 °F]. This portable infrared calibrator prioritizes exceptional stability, making it an ideal choice for the precise calibration of handheld infrared thermometers. With its generously sized black body, the IR2303 accommodates a diverse range of infrared thermometers, irrespective of the lenses they use. The calibrator maintains a fixed emissivity value of 0.95, ensuring consistent and accurate calibration results. It allows for temperature adjustments in precise increments of 0.1 °C.

To enhance the verification of the black body’s accuracy, a strategically positioned bore directly behind its surface facilitates contact-based measurements. This design not only supports real-time quality monitoring during the calibration process but also underscores the calibrator’s focus on accuracy and reliability in black body calibration applications.
