9133-156

Overview

The Fluke 9133-156 is a portable infrared temperature calibrator featuring a large, temperature-controlled blackbody target with a diameter of 2.25 inches (57 mm). It provides stable radiometric accuracy for calibrating non-contact IR thermometers and thermal imagers across a range of -30°C to 150°C (-22°F to 302°F), with extended certification up to 500°C. The unit incorporates solid-state cooling technology to reach low temperatures in normal ambient conditions and includes an RTD reference well for contact measurements. A front bezel dry gas fitting helps prevent ice buildup during operation.

Feature Summary

• Large 2.25-inch blackbody target providing a wide field of view for optical calibration
• Solid-state cooling technology enabling rapid stabilization at low temperatures
• Integrated RTD reference well for simultaneous contact temperature verification
• Front-mounted dry gas fitting designed to prevent ice accumulation on the target surface

Applications

• Calibration of non-contact infrared pyrometers
• Verification of thermal imaging cameras
• Field and laboratory temperature metrology
• Contact temperature measurement using RTD probes

Procurement Notes

Verify that the specific order includes the traceable calibration certificate required for compliance. Confirm the voltage rating matches your local power supply standards. Ensure the shipping container protects the precision blackbody target from physical damage during transit. Check for included accessories such as probe cables or carrying cases if specified in the purchase agreement.

Selection Notes

Select this model when a large target area is necessary for calibrating instruments with wide fields of view. Choose the 9133-156 over smaller variants if portability and rapid cooling are critical for field operations. Consider the integrated RTD well if contact measurements are needed alongside infrared calibration. Verify that the required upper temperature limit does not exceed 150°C for standard operation.

Part Context

This unit belongs to the Fluke Calibration 9133 series of portable infrared calibrators. It shares design principles with other models in the family but is distinguished by its specific temperature range and target size. The series is engineered for both laboratory precision and field durability, offering a balance between high radiometric accuracy and operational convenience for technicians.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific configuration. Users requiring different temperature ranges should consult the broader 9133 series lineup. Verify compatibility with existing calibration procedures before switching to alternative models.

FAQ
