Fluke 5626-15 Secondary Standard PRT Probe

*** Please Note: When ordering also specify the termination you require, ie. Fluke 5626-15-G (gold pins). X = termination *** Specify “A" (INFO-CON for 914X), “B" (bare wire), “D" (5-pin DIN for Tweener Thermometers), “G" (gold pins), “I" (INFO-CON for 1521 or 1522), “J" (banana plugs), “L" (mini spade lugs), “M" (mini banana plugs), “P" (INFO-CON for 1523 or 1524), or “S" (spade lugs). All models come without calibration unless calibration is purchased separately. Fluke Calibration's high-temp secondary standards fill the gap between affordable, but temperature-limited secondary PRTs (platinum resistance thermometers) and more expensive, highly accurate SPRTs (standard platinum resistance thermometers). The PRT is used with a readout device to detect temperature changes or actual temperature. The PRT covers the International Temperature Scale of 1990 (ITS-90) range from ?200 °C to 661 °C. Each PRT is carefully annealed at the appropriate temperatures and precisely tested for stability. The sensing element is fabricated using high purity platinum wire wound in a strain free design on a specially designed support. The ¼ inch O.D. Inconel 600 sheaths are sealed with a specially mixed gas and fit with a terminal box handle and strain relieved connection to the four-wire cable. Gold plated spade lugs terminate the wires. If you’re using block calibrators, furnaces, or temperature points above normal PRT (platinum resistance thermometer) temperatures (420 °C), then these two PRTs are for you. The 5626 is nominally 100 Ω and the 5628 is nominally 25.5 Ω. Both instruments have a temperature range of -200 °C to 661 °C. They make great working or check standards for calibration work up to the aluminum point. Using a regular PRT at temperatures above 500 °C exposes the platinum to contamination. If the PRT is used as a reference or calibration standard, contamination is a major problem. SPRTs (standard platinum resistance thermometers), which are more expensive and delicate, can handle the higher temperatures, but with greater risk to the instrument due to shock, contamination, or mishandling. The 5626 and 5628 are designed to reduce the contamination risk through the use of internal protection while not impairing performance.
