Fluke 9132/9133 Portable Infrared Calibrator with Blackbody Source

Reliable, Portable Blackbody Calibration for IR Thermometers and Imagers

Fluke’s 9132 and 9133 infrared calibrators are designed to meet the precise needs of infrared thermometer and thermal imager users. These portable blackbody sources offer fast heating and cooling, stable temperatures, and radiometric accuracy—making them ideal for field and lab environments alike.

Fluke 9132 – High-Temperature Blackbody Source (Up to 500 °C)

• Designed for IR calibrations above ambient
• Provides a stable blackbody surface up to 500 °C (932 °F)
• Short heating and cooling times keep workflows efficient
• Radiometric calibration ensures measurement confidence across its entire range

Fluke 9133 – Low-Temperature Blackbody Source (–30 °C to 150 °C)

• Ideal for calibrating IR thermometers at low temperatures
• Reaches –30 °C (22 °F) in typical ambient conditions using solid-state cooling
• Convenient dry gas fitting on front bezel prevents ice buildup on the target
• Offers stable temperature control up to 160 °C (320 °F)
• Heats or cools from ambient to either extreme in approximately 15 minutes

What is a Blackbody Calibrator?

A blackbody calibrator (or blackbody source) is a device that emits thermal radiation with high emissivity, typically near 1.0. This makes it behave closely to an ideal blackbody, emitting radiation according to Planck’s law.

Blackbody calibrators are essential tools for ensuring the accuracy of:

• Infrared thermometers
• Thermal imagers
• Non-contact temperature measurement devices

By aiming a device under test at the precisely controlled blackbody target, users can verify and adjust readings to ensure accuracy and compliance with calibration standards.

Summary: Why Choose the 9132 or 9133?

Both units provide:

• Portable, stable blackbody sources
• Quick heating and cooling times
• High emissivity targets for accurate infrared calibration
• Confidence backed by Fluke’s precision and reliability
