    don’t use the batteries that came with it

    After fighting to get an approval to buy a tach I went with the tach 20. I used the batteries that came with it and in 3 months they leaked and ruined the tach, now I’m stuck with a tach that don’t work, I needed it and could not use it and can’t get more money approved to get another one.

    ✘ No, I do not recommend this product

    Good Qulaity

    The unit is packaged in a nice storage case. The overall quality is what I would expect from Amprobe. The documentation is a little strange.

    ✔ Yes, I recommend this product.

    Great tachometer

    I bought it because of several important features
    1, Metric units especially m/s (others have only m/min)
    2. The speed wheel was quite large so that I could hold the body of the tachometer flat on the conveyor surface
    3. Average speed (my previous one only did max/min and last)
    4. NOT made in China (I hope). The company where I work bought 3 Chinese-made units and they were in error by 3% as-purchased. Our control system requires speeds set to within 0.5% so it caused faults all the time.

    ✔ Yes, I recommend this product.
