KYB offers a digital dial for manometers that can be adapted to the 891 135 analog manometer, to provide a more accurate digital pressure reading. It replaces the traditional display to minimize reading errors due to inconspicuous needles or graduations. The digital dial enables fine adjustment of suspension or inflation settings, improving control, consistency and safety of use. Designed to withstand vibration and workshop conditions, it is a reliable tuning tool for demanding professionals and amateurs alike.
