  FLUKE 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.

  FLUKE 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.
