Fluke 5616-12-G Probe, Secondary PRT, 100 OHM (1/4 X 12 INCH). You won't find another NIST-traceable reference temperature sensor that matches the accuracy and temperature range of the 5616 for the same price. The 5616-12 is a 100-ohm platinum resistance thermometer (PRT) with excellent short-term repeatability and comes with an unaccredited NIST-traceable calibration. The temperature range of the 5616 covers -200 °C to 420 °C, and its high-purity platinum element and durability make it great for calibrating in the lab or in the field. When choosing a reference with a platinum element, there are two things you want to look at carefully: the short-term repeatability and the long-term drift. When PRTs are thermally cycled over their temperature range as they would be during a calibration, their resistance at the triple point of water can move up and down within an expected range. Fluke Calibration defines this range (called "short-term repeatability) as the repeatability at the triple point of water during three thermal cycles. 5616s are among the best performing in their class with short-term repeatability better than ± 0.010 °C (± 0.004 °C is typical). In addition, the 5616's drift is ± 0.007 °C at the triple point of water when exposed up to its maximum temperature (420 °C) for 100 hours. These specifications are given at k=2 and therefore include a 95 % confidence level. The 5616's sealed ¬INCONEL® 600 sheath is 298 mm (11.75 in) long and 6.35 mm (0.250 in) in diameter. The probe's PTFE-jacketed cable is made of silver plated copper that ends with four-wire leads, which eliminate the effects of lead-wire resistance on measurements. Use the 5616 with Fluke Calibration's 1523/1524 Handheld Reference Thermometer, 1560 Black Stack, 1529 Chub-E4, or 1502A Tweener thermometer readouts. Each sensor comes with a manufacturer's report of calibration
