When buying a PRT or RTD temperature probe, performance isn’t the only criterion you need to look at. The real issues are price-to-accuracy and price-to-durability ratios.

5627A probes have a temperature range up to 420°C and accuracy as good as +/- 0.025°C. They come in three different lengths.  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. Why use a precision thermometer or RTD temperature probe that’s less accurate than your meter?

The 5627A is manufactured using a coil suspension element design for increased shock and vibration resistance. It has a mineral-insulated sheath with a minimum bend radius of 19 mm (3/4-inch) for flexibility and durability. (Bend, if any, should be specified at time of order.)

Six- and nine-inch 5627A precision thermometers are calibrated at –196°C, –38°C, 0°C, 200°C, and 300°C. For 12 in versions of these precision thermometers, the point at 300°C is replaced by a calibration point at 420°C.

Each probe is individually calibrated and includes a NVLAP-accredited report of calibration from the manufacturer.

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!

 • Vibration and shock resistant
