What is Vion?

Everywhere around you--whether at home or work--all energy-consuming products utilize electricity, and if something goes wrong, most of us don’t know enough about electricity to fix the problem as fast as we’d like. This is why Vion was born, bringing to you the first smart multimeter that makes it easy to diagnose and fix electrical problems.


Vion measures voltage and resistance, has a pair of probes without a body, and allows you to see the break down of electricity-powered products on your smartphone.


Most multimeters require you to turn the rotary switch to select measurement items and have electrical knowledge to understand the number displayed on the LCD in order to determine the fault. However, Vion can link to your smartphone and can automatically measure the product without having to select a measurement item. Vion diagnoses the measurement result as “Good/Bad” through voice guidance.
