Temperature CalibratorsFLUKE 724 Temperature Calibrator
Everything you need to troubleshoot and calibrate temperature sensors and transmitters
The Fluke 724 is powerful yet easy-to-use temperature calibrator that sources and measures 10 thermocouple types, and 7 RTD types, plus volts and ohms. It also measures mA while simultaneously supplying loop power to the transmitter. Use it to test and calibrate almost any temperature instrument, so you only need one tool to expertly test all the temperature sensors and transmitters in your plant.
The Fluke 724 even handles high-speed pulsed RTD circuits and provides loop power. The dual-line measure/source display lets you source temperature and view loop current at the same time. And with its simple, “no menus” controls, you’ll be able to get all your testing done faster. Whether you’re performing fast linearity tests using the 25% and 100% step functions, or performing a remote test using the auto step or auto ramp feature the Fluke 724 will help you get the job done.
Built to help you work quickly
With its compact, easy-to-carry streamlined shape, the Fluke 724 also features a bright backlit display that lets you work in low light conditions. The large battery capacity (four AA alkaline batteries) gives you long runtimes, and the easy-to-access battery door makes it quick to change out batteries when necessary. All this in a rugged, reliable package designed to stand up to field use.

Temperature CalibratorsFLUKE 9190A Ultra-Cool Field Metrology Well
Ideal for cleanroom environments and demanding calibration work
Cleanroom-Compatible, Ultra-Portable, and Fast
Traditional calibration baths are known for stability and uniformity—but they’re far from ideal for cleanroom use. Their large size, fluid handling requirements, and potential for spills or vapors make them a poor fit for controlled environments.
The Fluke 9190A Ultra-Cool Field Metrology Well offers a smarter solution. Designed specifically for cleanrooms and critical process industries, it provides:
- Wide temperature range suitable for pharmaceutical, biomedical, and food processing needs
- Compact, lightweight design for easy transport and field use
- No heat transfer fluids, keeping your environment contaminant-free
- Faster heating and cooling times than traditional calibration baths—so you complete calibrations faster
Precision You Can Trust for Process Accuracy
Accurate process measurements are essential for quality control. Inaccurate data can lead to product recalls, regulatory penalties, lost profits, and reputational damage. That’s why your calibration equipment needs to be just as dependable as your measurement systems.
The 9190A Ultra-Cool Field Metrology Well delivers:
- Best-in-class accuracy, stability, and uniformity
- Designed using decades of Fluke dry-block technology expertise
- Conformance to EURAMET cg-13 best practices for temperature block calibrators
- Thoroughly tested specs for axial and radial uniformity, hysteresis, and loading effects
Make Every Measurement Count
When you use the 9190A, you’re choosing the most accurate and stable ultra-cool dry-block calibrator available. That confidence translates into better product quality, more efficient compliance, and measurable business impact.

Temperature CalibratorsFLUKE Calibration 6102/7102/7103 Micro-Bath
Portable and extremely stable
Need portability and extreme stability? Fluke Calibration Micro-Baths have both. We invented the Micro-Bath. And, while many have tried to duplicate it, none of them use proprietary Fluke Calibration controllers, so none of them deliver performance like a Fluke Calibration bath. Micro-Baths can be used anywhere for any type of sensor. The 6102 weighs less than 4.5 kg (10 lb.), with the fluid. It’s lighter and smaller than most dry-wells, has a spill-proof lid, and is easier to carry than your lunch. You can take it where you need to go without carts or excessive effort. Micro-Baths can even be transported with the fluid in them.
Wherever you go with your Micro-Bath, you can count on its performance. Each model is stable to ±0.03 °C or better, depending on the fluid you use. Uniformity is ±0.02 °C or better for low uncertainties using a reference thermometer. Display accuracy has been improved to ±0.25 °C for quick calibrations without a reference thermometer. In short, you get the stability and precision of a liquid bath in a dry-well-sized package. Don’t be fooled by competitors who pour oil into a dry-well and call it a bath. Micro-Baths are maximized for true fluid-bath performance.
With a 48 mm (1.9-inch) diameter, 140 mm (5.5-inch) deep tank, a Micro-Bath can calibrate any type of sensor including short, square, or odd-shaped sensors. The problems of fit and immersion are virtually eliminated by using a fluid medium rather than a dry-block calibrator. Micro-Baths are perfect for liquid-in-glass and bimetal thermometers.
The 6102 has a temperature range from 35 °C to 200 °C, the 7102 covers –5 °C to 125 °C, and the 7103 extends from –30 °C to 125 °C. Stability, uniformity, and accuracy specifications cover the entire range for each bath, not just the best temperature.
All Micro-Baths have RS-232 ports and can be used with MET/TEMP II software (described on page 81). Also included are contacts to calibrate a thermal switch, eight set-point memory storage, ramp-rate adjust, and over-temperature safety cutout.
You may have noticed we haven’t touted our CFC-free refrigeration. Yes, cold Micro-Baths are CFC-free, and also compressor-free. That’s right—no heavy, noisy compressor to lug around. We achieve our temperature range and stability with only one moving part. This means more durability and less weight. Fluke Calibration manufactures and sells temperature calibration baths of every size and shape, and now we have the smallest and lightest baths in the industry to go with the dozens of other models we make.
Look at the specs, price, and value of these portable instruments and you’ll know why Fluke Calibration is the number-one company in this business.
