The UPS4E current loop calibrator is now also available in an ATEX version

At the end of 2025, we introduced the UPS4E from DRUCK – a robust, pocket-sized current loop calibrator that replaces the tried-and-tested UPS-II and UPS-III models. The UPS4E impresses with its maximum reliability and portability and is ideal for testing, maintenance work and valve calibration.

The device is now also available as an Ex/ATEX version: the UPS4E-IS has been specially developed for use in potentially explosive atmospheres and is designed for convenient one-handed operation. It enables the reliable testing and power supply of mA control loops and devices, making it an indispensable tool in the field.

An easy-to-read display and user-friendly, time-saving functions – including step, measurement range and valve testing – make the UPS4E-IS the ideal solution for the efficient maintenance of measuring instruments.
