Hart Scientific: New PRT
January 27, 2005
Hart Scientific recently announced a new 10-ohm platinum resistance thermometer (PRT), model 5624, which can read temperatures as high as 1000C. The new unit's sensor design allows for PRT performance at very high temperatures, making it a suitable standard for calibration of high-temperature RTDs and thermocouples. Model 5624 includes a NIST-traceable, NVLAP-accredited fixed-point calibration covering the range of 0 to 962C. Accuracy (including short-term stability and calibration uncertainty) of +/-0.055C is provided over the full range of calibration. After one year of use, the model 5624 drifts less than 10 mK at 0C.
