Review on πŸ”’ Accurate Tachometer Protmex for Precise 50-19999RPM Measurement with Backlight by Charles Barney

Revainrating 1 out of 5

Very inaccurate

This thing had one job - measure speed. Do it with a bang. I attached the conveyor with a known precise hand stroke at a known speed and the thing deflected at over 10 feet per minute. If accuracy is important, then this is not your hand tactic.

Pros
  • Rev counter
Cons
  • Outdated
