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

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 Pro is the universal variant from this range of instruments - a high-precision, handheld calibrator for electrical quantities with integrated 24 V loop power supply. It unites measurement and simulation functions into a single compact instrument and covers all common signal types for process and laboratory measuring technology. A genuine all-rounder for daily use in industrial environments.
