The Most Accurate & Stable Calibration Bath In Its Class

 

Calibration baths are the most stable and uniform temperature sources available, but they aren’t a good fit for cleanrooms. The size of a bath limits its portability, and bath fluids can easily spill and give off vapors.

 

 

The Fluke 9190A Ultra-Cool Field Metrology Well is a great alternative. Its wide temperature range brackets the coldest and highest temperature ranges required for pharmaceutical, biomedical and food processing applications.

 

The 9190A is small and lightweight, making it easy to transport. And since it does not use heat transfer fluids, cleanrooms stay clean. The 9190A cooling and heating times are faster than a calibration bath—that means calibration work gets done more quickly.

 

 

The Calibrator has two models: the 9190A and the 9190A-P. The 9190A-P is a “Process” version of the 9190A that combines the heat source with a built-in thermometer input panel. The Input Panel includes an input for an external reference/control thermometer that makes it possible to perform a transmitter loop calibration, comparison calibration, or a simple check of a temperature sensor. In addition, the Input Panel can read resistance and current from a probe. For probes that require power to operate, the 4-20 mA input has a loop-power function that can source up to 24 volts of power.
