Cooling Method: Peltier Elements.
1Accuracy for one year with ambient 20°­26°C. Accuracy may be enhanced by using external reference probe.
2Measured for 24 hours with ambient 20°­26°C.
3Measured with Rosemount 162CE as follows: 1. Measure temperature at 100°C. 2. Heat to maximum (500°C for Universal Jaw, 700°C for 5 hole block). 3. Remeasure at 100°C. The difference between 1. and 3. is <0.05°C.
