GE Druck DPI 104‑IS Intrinsically Safe Digital Test Gauge

GE Druck DPI 104‑IS is an intrinsically‑safe high‑precision digital pressure test gauge for hazardous‑area pressure measurement and calibration work. It adopts silicon pressure‑sensor technology, delivering 0.05%FS measurement accuracy, and supports gauge, absolute and sealed‑gauge pressure‑measurement modes for gas‑liquid medium pressure‑testing in explosive‑risk zones.

This gauge has ATEX / IECEx Zone0 intrinsic‑safety certification, powered by 9V battery, with large 5‑digit LCD display, unit switching, min/max‑value capture, tare and alarm‑output functions. RS232 communication supports daisy‑chain multi‑instrument networking. It is widely used as replacement spare‑part for on‑site troubleshooting, instrument‑calibration‑work and hazardous‑zone‑system retrofit projects.
