Druck Launches UPS4E-IS, the World’s Only Intrinsically Safe Pocket-Size Loop Calibrator

New Calibration Technology Enhances Performance in Commercial and Hazardous Area Applications

Druck, a Crane Company business and a leader in pressure measurement and instrumentation, has launched the UPS4E‑IS, an intrinsically safe, pocket‑size loop calibrator that sets a new benchmark for calibration in commercial and hazardous area applications. The UPS4E‑IS is the only intrinsically safe compact pocket-size loop calibrator available in the market today.

“Its introduction reinforces our commitment to providing innovative calibration solutions that empower technicians and engineers globally.” - Gordon Docherty, President of Druck.

Designed for instrumentation technicians and maintenance engineers, the UPS4E-IS is an easy‑to‑use handheld device that sources and measures 4–20 mA signals in a single unit, with inbuilt datalogging to simplify testing, calibration and troubleshooting. By eliminating the need for multiple tools, it helps users save time, reduce complexity and improve accuracy in the field, measuring current and voltage with 0.01% accuracy.

ATEX‑ and IECEx‑certified for Zone 0 environments, the UPS4E‑IS combines a rugged design with long‑lasting performance for safe, dependable operation in the harshest conditions. It delivers up to 100 hours in measure mode and 18 hours when powering a 12 mA loop—nearly double the typical battery life—setting a new benchmark for endurance in the field.

“Leveraging Druck’s long‑standing expertise in dependable loop calibration, the launch of the UPS4E-IS marks a significant leap forward in enhancing efficiency for handheld electric loop calibration for commercial and hazardous area applications,” said Gordon Docherty, President of Druck.  “Its introduction reinforces our commitment to providing innovative calibration solutions that empower technicians and engineers globally.”

Building on the launch of the UPS4E in 2025 — the smallest electrical loop calibrator on the market — the UPS4E‑IS is the next‑generation replacement for the popular UPS-II-IS and UPS-III-IS series.

The new technology has already been piloted by select customers who have praised its compact design, ease of use, accuracy, reliability, and time-saving features, all of which contribute to improvements in productivity.
