The Fluke Calibration 5627A Precision Industrial PRT (formerly Hart Scientific) have a temperature range up to 788°F(420°C) and an accuracy as good as ± 0.025°C. They come in three different lengths. (Both six- and nine-inch models cover -328°F(–200°C) to 572°F(300°C).) Each precision thermometer is shipped with its ITS-90 coefficients and a calibration table in 1°C increments.

One of the best features of this sensor is that it conforms to the standard 385 curve, letting you use your DIN/IEC RTD meters fully. The 5627A is manufactured using a coil suspension element design for increased shock and vibration resistance.

Six- and nine-inch 5627A precision thermometers are calibrated at -320.8°F(–196°C), -36.4°F(–38°C), 32°F(0°C), 392°F(200°C), and 572°F(300°C). For 12-inch versions of these precision thermometers, the point at 300°C is replaced by a calibration point at 788°F(420°C).

Each probe is individually calibrated and includes a NVLAP-accredited report of calibration from the manufacturer, lab code 200706-0.

This RTD temperature probe is an excellent value for a precision thermometer. It has the price-to-accuracy and price-to-durability ratios you should demand in all of the precision thermometers you buy!
