For all your test equipment requirements

Yokogawa CA12E Handy Temperature Calibrator


Compact, Low Cost, Versatile Handheld Calibrator

Designed for simple operation and high performance. The voltage and current calibrator CA12E can supply and measure signals of up to 30 V DC, 24 mA DC and has a current SINK function

The Yokogawa CA12E temperature calibrator generates and/or measures (as selected) 100 mV, six types of TCs (K, E, J, T, N, and R), 400 Ω, and RTD range. The CA12 incorporates the reference junction-temperature compensation function and also includes the thermometer function for the multiple TCs and the RTDs.
