Replacing the legacy UPS-III (and UPS-II) loop calibrator, the UPS4E is a modern, cost-effective device that is available on competitive lead times.

The UPS4E is engineered to be a necessary tool for loop testing, excelling at powering process control mA loops and mA devices. Ideal for instrument maintenance, it features an easy-to-read display and user-friendly, time-saving functions such as step, span, and valve check.

This rugged and ultra-compact device is designed for one-handed operation, making it incredibly convenient for fieldwork. Its small size allows it to fit comfortably in the top pocket of an overall, continuing the legacy of the beloved UPS-II and UPS-III models.

The UPS4E Loop Calibrator is perfect for instrument maintenance, offering an easy-to-read display and simple-to-use, time-saving features. These include step, span, and valve check functionalities, which streamline your workflow and enhance productivity.
