The original and still the best genuinely professional tachometer. This race-proven and award winning design guarantees exceptional accuracy and robustness over many years of use.
Professional Tachometers now feature RPM data acquisition and on-dial playback as standard recording up to 25 minutes of RPM history.
The ST400 Recording Tachometer was Stack’s first product, which in its day (more than twenty five years ago) provided the only on-vehicle solution for accurate RPM display and logging. As a direct result, this unit immediately gained widespread acceptance with Formula One teams and all forms of professional motorsport.
These tachometers have a 3.5”/88mm bezel and are a direct replacement for most standard tachometers.
