Fluke calibration 4180-256 Temperature Calibrator

This temperature calibrator is a portable precision infrared device designed to provide traceable temperature references for infrared thermometers and thermal imagers in laboratory, field and process environments. It operates from an AC supply and is supplied with an accredited radiometric calibration report, user documentation and Interface software to enable consistent, emissivity-minimised measurements across a useful temperature band.

• ±0.35 °C accuracy calibrator delivering high-accuracy readings
• Radiometrically calibrated for reduced emissivity-related uncertainty
• Target diameter 152.4 mm provides correct field-of-view coverage
• Fast temperature response supports timely in‑situ calibrations
• NVLAP-accredited calibration report included for traceability
• Portable temperature calibrator 9.1 kg for convenient transport

• Suitable for thermocouple calibration −15 to 120 °C in labs
• Used with infrared thermometers for routine field verification
• Ideal for thermal imager uniformity checks over large targets
• Can be used for process-control thermometer validation on-site
• Used for quality audits requiring accredited radiometric references

It accepts AC input and is specified for 115 V AC or 230 V AC supplies with appropriate fuse ratings depending on mains voltage.

The target exhibits low centre-area variation, with uniformity measured across the central diameter to support consistent multi-pixel imager readings.

A target cover, user guide, getting-started guide, and 9930 Interface‑it software with its user guide are included.

Heating and cooling times are staged to reach specified temperatures rapidly to minimise downtime during calibration tasks.

Yes, it offers an RS-232 computer Interface for connection to external systems.
