The Gossen Metrawatt M275P is the METRACAL CM PRO model in the METRACAL CM series, combining a multimeter and process calibrator in a single portable device. Designed for the precise measurement and simulation of electrical quantities, it is particularly well-suited for service, commissioning, maintenance, and calibration tasks in process measurement technology. Thanks to its dual-mode capability, measurement and calibration functions can be used simultaneously, allowing, for example, the simulation of an input signal and direct monitoring of the resulting output signal. The device supports voltage, current, resistance, frequency, and temperature measurements, among others, and enables the calibration of RTD and thermocouple sensors. Its functionality is further enhanced by an integrated data logger, individually storable test profiles, a robust housing with IP52 protection, and a Bluetooth interface for data transmission. The M275P is therefore a versatile solution for demanding calibration and testing tasks requiring high accuracy, portability, and flexible signal processing. Particularly noteworthy are the galvanic isolation of the measuring and calibration sections, the precise 2-, 3-, and 4-wire resistance and RTD measurements, and the ability to save frequently used settings directly in the device.
