Fluke Temperature Calibrator, ±0.35°C Accuracy, 9.1kg Weight - 4180-256

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.

Features and Benefits:

• ±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

Applications

• 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

What power arrangements are required to operate it?

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

How uniform is the thermal target across its surface?

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

What accessories are supplied to begin calibrations immediately?

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

How long does it take to reach operating temperature from ambient?

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

Does the instrument support computer interfacing for data capture?

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