Druck UPS4E Handheld Electrical Loop Calibrator

The UPS4E is a rugged and extremely compact loop calibrator, designed to be operated with one hand. It is an essential tool for loop testing/powering process control mA loops and mA devices. Perfect for instrument maintenance with an easy-to-read display and simple-to-use time saving features including step, span and valve check.

The UPS4E utilises the most advanced electrical calibration technology to create a dependable, cost-effective loop calibrator.

The UPS4E is a handheld device used to test and calibrate current loops in industrial control systems. It can source, measure, or simulate a precise electrical current—typically in the 4–20 mA range—allowing technicians to verify the performance of sensors, transmitters, and control systems. It also provides 24V loop power, making it an essential tool for troubleshooting and maintenance in process automation environments.
