5681, 5683, 5684, and 5685 Quartz-Sheath SPRTs

Choosing the right platinum thermometer as your primary standard may be the most critical purchase decision in your lab. Unfortunately, other manufacturers are pretty secretive about how their SPRTs are made. They wont tell you much more than you can already see by looking at one. Long-term reputation used to be a reliable indicator, but the leaders of a few decades ago have lost their original craftsmen and design scientists. There are only a few active SPRT design groups in the world today.

So how do you know youre making the best purchase? Self-proclaimed expertise shouldnt convince you. You should expect some sound evidence that the company is qualified in the ongoing science of SPRT development. At Fluke Calibration well tell you how we make an SPRT. Well let you talk to the people here who design, build, and calibrate SPRTs. Finally, when you buy one, if you dont like it, well take it back and return your money.
