  • Very accurate tachometer

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:

    Tachometer makes very accurate measurements on low and high speed. I have lathe machine tool with variable rotation speed and digital speed indication so I have compared the data:
    - on speed 25 rpm tachometer showed 25 rpm;
    - on speed 525 rpm tachometer showed 532 rpm.
    Also measured the speed of emery wheel. Nominal speed of it is 1400 rpm and tachometer showed 1380 rpm.

    Cons:

    Have no cover for infrared diode for storage - be careful with your eyes when you take thermometer out of storage box.

    OtherThoughts:

    Comes with good quality holder - no needness to buy case for it.

    Bottomline:

    Accurate tachometer with very good price.
