Product Highlights

With support for both field verification and laboratory standard testing, the RM‑111 connects directly to meter outputs or reference pulses, prompts the user for setup parameters (such as Kh and test duration), then captures pulses, computes registration or error percentages, and optionally stores or transmits results.

It integrates seamlessly with RADIAN’s test accessories and software, enabling efficient data collection, reporting, and automation.
