Review on 🔀 Mengshen Tachometer: Accurate Non-Contact Rotation Measurement Tool by Curtis Donjuan

I use it for work, mainly measuring the linear speed of conveyor belts. I use the wheel to make contact to measure speed. For the price, this little device is great. The best I can say is very accurate. I did not use the indirect laser measurement function as it does not apply to my work. I have seen comparable models for many more. This is great value.
