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.

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.

Intrinsically SafeFLUKE 1551A/1552A Intrinsically Safe Thermometers
Product overview: Fluke 1551A/1552A Intrinsically Safe Thermometers
The Fluke 1551A “Stik” Thermometer provides a temperature range—50 °C to 160 °C (-58 °F to 320 °F). The Fluke 1551A delivers repeatable temperature measurements accurate to ±0.05°C over its full range. It is rated intrinsically safe for working in indoor or outdoor environments where potentially explosive gases may be present. It’s a great choice for environments that aren’t potential explosive as well such as the floor of a processing plant. The battery operated, portable reference thermometer is a great choice for daily checks of working thermometers, custody transfer temperature determination, PET calibration, LIG calibration, and temperature transmitter calibration and verification.
The stainless steel probe and digital readout are fixed together and calibrated as a system. The large backlit LCD display rotates 90° degrees making it easy to read from any angle. And a user-configurable stability/trend indicator lets you know when your temperature is stable enough to record an accurate measurement. A user-settable auto-off function extends typical battery life to up to 300 hours. And the low-battery indicator and stop-measure function prevents erroneous measurements from being made due to a low battery. Plus you can easily and accurately calibrate the 1551A with a simple three-point calibration function.
Other useful features:
- Delivers 300-hour battery life
- Shows percent battery-life and low-battery indicators
- Includes NVLAP-accreditation and NIST-traceable calibration
