Standard Platinum Resistance Thermometers(SPRTs)
1. AccuMac 1860-25
?
Standard Platinum Resistance Thermometers (SPRTs) are common used to interpolate temperature in the range from -189.3442 °C to 660.323 °C on the International Temperature Scale of 1990 (ITS-90). They are widely used as standard or reference thermometers to calibrate other thermometers and to measure temperature precisely in primary and secondary laboratories. AM1850 and AM1860 SPRTs are the crown jewels of AccuMac temperature probes. It takes decades of our scientific expertise and original craftsmanship to create these world class products. They feature a very low drift rate.
