2553A Precision DC Calibrator
Brand: Yokogawa Electric CorporationThe 2553A provides popular K, T, E, J, and an additional 6 types of thermocouples.
These 10 types are all regulated in IEC. It also provides widely used Pt100 as an RTD.
Resistance as well as temperature value can be set as an output value, enabling instrument calibration by both values.
