High-precision multimeter and process calibrator for measuring and simulating electrical variables with integrated mA loop function and HART communication

The Metracal CM range is redefining the standard for mobile calibration technology. As multifunctional process calibrators for electrical quantities, they combine maximum measurement precision with user-friendly operation and state-of-the-art communication capabilities.

Featuring dual mode operation, programmable sequences, an integrated data logger and Bluetooth connectivity, these instruments are designed for documented, efficient calibration processes in laboratory, production and field service applications.

The Metracal CM Tech extends the PRO version with an integrated HART interface for direct communication with intelligent field devices. As a result, it’s not only possible to perform electrical testing on transmitters and measuring transducers: their parameters can also be configured and they can be diagnosed – without the need for any additional hardware. The instrument unites precision, communication and efficiency - the ideal tool for modern process instrumentation.
