UNI-T UT725 Multifunction Process Calibrator

From the shop's description

UNI-T UT725 Multifunction Process Calibrator The UNI-T UT725 multifunction process calibrator is a handheld, battery-powered instrument designed to streamline a variety of calibration tasks in industrial environments. At its core, it combines both a temperature process calibrator and a loop-calibrator into a single tool, enabling technicians to both source and measure key process signals without switching devices. Users can generate and read out milliamp (mA) loops, DC voltage, temperature via thermocouples or RTDs, resistance, frequency, and more—all from the same unit. The UT725’s intuitive interface and clear LCD allow real-time simultaneous measurement and output of different process parameters, minimizing steps when verifying or troubleshooting transmitters, sensors, and control loops. Built with a rugged housing and powered by six AA rechargeable batteries, the UT725 is portable enough to carry into tight plant spaces or take out in the field for on-site work. Its precision sourcing and measurement accuracy (down to 0.02 %) ensure that loop calibrations, transmitter checks, and temperature verifications meet exacting standards. Contrast adjustment and an auto-power-off feature help extend battery life, while onboard storage lets users save and recall up to several custom setups. For advanced tasks, a USB port enables communication with a PC for data logging or firmware upgrades. Overall, the UT725 is tailored for maintenance engineers and technicians who need a single, reliable instrument to handle loops, temperature, frequency, and resistance calibrations across diverse industrial applications. Features: Step/Ramp functions. Source and measure accuracy up to 0.02 %. Rechargeable battery operation. Contrast adjustment for the display. Auto-power-off (time adjustable). Stores and recalls user-defined setups. USB communication for data logging and updates. Simultaneous real-time measurement and output of different process signals. Pressure measurement (with specified pressure modules) and pressure sourcing. Provides 24 V loop power to a transmitter while performing mA current measurement concurrently.
