Isotech 989 Blackbody Calibrator

Fits calibration and checking of infrared thermometers and thermal imagers around body/ambient temperatures using an Isotech Model 989 portable blackbody source settable about 20 °C to 50 °C.

Key advantages

• 20…50 °C blackbody — Near-ambient / medical IR calibration band.
• ±0.2 °C class — Combined accuracy/stability about ±0.2 °C; short-term stability typically <0.01 °C class.
• 0.01 °C resolution — Front-panel digital temperature controller.
• High-emissivity target — Compact benchtop radiation blackbody for IR thermometers and imagers.

Typical applications

• Checking IR thermometers around body/ambient temperatures.
• Thermal imager verification in the near-ambient band.
• Benchtop blackbody work that does not need industrial high-temperature sources.

Selection guide

• Temperature range — About 20 °C to 50 °C settable blackbody temperature.
• Accuracy / stability — Combined accuracy/stability about ±0.2 °C; short-term stability typically <0.01 °C class.
• Resolution — Controller resolution 0.01 °C.
• Emissivity — High-emissivity blackbody cavity / target for radiation thermometer calibration.
• Form — Compact benchtop blackbody calibrator with front-panel digital controller.

Common mistakes

• Expecting industrial high-temperature blackbody ranges — 989 is about 20…50 °C near-ambient/medical band.
• Confusing combined accuracy/stability (~±0.2 °C) with short-term stability (<0.01 °C class).
• Ordering for contact probe calibration — this is a radiation blackbody target, not a dry-block well.
• Ignoring emissivity/FOV match between the DUT IR thermometer and the cavity/target.
• Leaving supply/region blank on the RFQ for a benchtop controller unit.

When to RFQ / what to tell us

1. DUT IR thermometer/imager models, target temperature points within ~20…50 °C, and required uncertainty.
2. Quantity, ship-to country, and mains supply preference.
3. Any accreditation certificate needs beyond standard OEM documentation.
