Review on TWTADE TWTADE 4 Digital Tachometer RPM Green LED With Wire Magnet Hall NPN Proximity Switch Sensor Holder ZSB5JT G by Predrag Williams

This tachometer is a game changer! The green LED is easy to read and the magnet and proximity switch make it SIMPLE to install. It tracks speed precisely and has been incredibly useful in our industrial and scientific settings. The only downside is that the instructions weren't as clear as we would have liked but with a little research and experimentation, we were able to get it up and running quickly..
