Standard Platinum Resistance Thermometers

Choosing the right standard platinum resistance thermometer (SPRT) as your primary standard may be the most critical purchase decision in your lab. Fluke Calibration has one of only a few active SPRT design groups in the world today. Our SPRTs have all the features you would expect in a world-class design -- gold-plated spade lugs, a strain-relieved four-wire cable, convection prevention disks, the finest quartz glass available, delustered stems, and the purest platinum wire available.
