Fluke's Hart Scientific division makes everything you need for calibrating temperature sensors including SPRTs, PRTs, thermistors, and thermocouples. Our constant temperature baths and dry-block calibrators offer unmatched stability, and our primary temperature standards are used in national metrology institutes around the world. For precision thermometry, our thermometer readouts and probes are exceptionally accurate and easy to use, and our temperature and humidity data logger handles your environmental monitoring needs. We also offer temperature calibration training courses. Our NVLAP-accredited laboratory (lab code 200348-0) has some of the lowest accredited uncertainties, and its quality assurance manual complies with ISO/IEC 17025 and ANSI/NCSL Z540.

Size matters!

Is credibility important to you? Business decisions costing thousands of dollars are based on the results of your measurements, so they had better be right! Learn more about the new 418X Precision Infrared Calibrators because credibility is important, size matters and radiometric calibration is a must have.

Upgrade to the 1620A “DewK”

The new DewK can be networked wirelessly or via ethernet, the latest from paperless temperature and humidity data loggers. Optional LogWare III contacts you using email or text messaging when there’s a problem. DewK sensors are individually calibrated, so you can easily swap one out for recalibration and use a spare with no lost monitoring time. Find out how you can monitor temperature to ± 0.125 °C and humidity to ± 1.5 %RH.

Metrology Wells

With groundbreaking new proprietary electronics (patents pending), Metrology Wells let you bring lab-quality performance into whatever environment you might work in. New analog and digital control techniques provide stability as good as ± 0.005 °C. And with dual-zone control, axial uniformity is as good as ± 0.02 °C over a 60 mm (2.36 in) zone. That’s 60 mm! Performance like that just doesn’t exist in dry-well or dry-block calibrators. See the demo.
