PRECISION DC CALIBRATOR 2553A Yokogawa

The 2553A provides well used 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.

The 2553A Precision DC Calibrator, like our other Calibrators and Sources, offers users the simple operation and reliability they have come to trust from Yokogawa.
