True Phase Identification System

Our vision has always been to create a phase identification system that exceeds any of today’s industry quality, safety and efficiency requirements. SPI-III’s unique design consists of a wireless bi-module combo that is stunningly easy to configure and operate. With many advancements and innovations, SPI-III will be more helpful than ever before, enabling field applications such as identification of A-B-C electrical phases from all 50 and 60 Hz networks, switchgear phase concordance (matching), phase rotation, system paralleling, underground phasing applications and more.

NEW: Our new Presets feature enables you to effortlessly save and load your preferred settings with a single tap. Seamlessly switch between different setups for various tasks, ensuring optimal performance each time. Please note that Presets can be created from your web portal. Feel free to contact us to gain access to this portal.

NEW: Now available with Annotations! Enhance your work and collaboration process with Annotations. Have you ever wanted to attach a picture while saving your phase ID recording? Now, not only can you effortlessly add pictures, but you also have the option to include text, voice messages, and videos.
