Product Information

Ideal for cleanroom environments and demanding calibration workCleanroom-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 CountWhen 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.
