UNI-T UT725 Documenting Multifunction Process Calibrator

UNI-T UT725 Documenting Multifunction Calibrator

The UNI-T UT725 Documenting Multifunction Calibrator is a portable, all-in-one documenting calibrator designed for field calibration technicians, instrumentation engineers, process control specialists, and factory maintenance teams. Available in Sri Lanka, this advanced multifunction calibrator provides a comprehensive solution for sourcing, measuring, documenting, and troubleshooting a wide range of industrial process signals.

Offering functionality comparable to high-end calibrators such as the Fluke 754 Documenting Process Calibrator and Beamex MC4, the UT725 combines precision, versatility, and portability in a rugged field-ready design. It can source and measure current, voltage, resistance, frequency, temperature, and pressure (via optional modules), making it ideal for calibration and maintenance tasks across industrial environments.

With built-in USB data logging, simultaneous source and measurement capabilities, integrated 24V loop power, and support for multiple thermocouple and RTD types, the UNI-T UT725 is a powerful tool for calibration professionals seeking efficiency, accuracy, and complete field documentation.
