SPRT is 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. AM1950 and AM1960 SPRTs are the crown jewels of Accomac temperature probes. It takes decades of scientific expertise and original craftsmanship to create these world-class products. They feature a very low drift rate. AM1950 has a temperature range from -200°C to 500°C. AM1960 covers range from -200°C to 670°C.
