Current / Voltage Calibrators
Portable and handheld calibration devices for Voltage and Current are used in various process technology and control engineering applications. For measuring or sourcing, Current/Voltage calibrators can bring measured values as close as possible to the true value, and provides a precision source for current and voltage measurements. With the calibrators, voltage and current can be generated or measured to compensate the systematic errors of any control devices (e.g. pressure transmitter), as well as compensate the measured temperature by eliminating the cold conjunction errors (e.g. thermocouples).
A high precision calibration unit for voltage, current and thermocouple combines high accuracy, low drift, low noise, and superior long-term stability with multiple functionality and simple operation.
