Precision DC calibrator M160 is a portable source of industrial process signals for calibration of multimeters in laboratories as well as on site calibration of evaluation units and other process meters. High load capacity of both voltage and current outputs, robust design and exceptional 20 ppm accuracy over 20°C-wide reference temperature range make this calibrator great for demanding conditions in production facilities. Other functions include thermocouple and RTD simulation, resistance and frequency, all with accuracy and resolution to meet all requirements. With option 91 the calibrator can measure temperature directly at output terminals and compensate the cold junction effect.
