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

    Pros:

    - Good build quality devices
    - Storage pouch included
    - Reflective tape labels on a rotating part

    Cons:

    - Precision is not very high
    - Speed values change frequently

    OtherThoughts:

    Digital tachometer scale constantly changes speed, but the rotor rotates at a constant speed.

    Bottomline:

    I used this device to measure the speed of rotation of the rotor viscometer when writing a thesis. Accuracy was pretty low, but I had enough. For use in areas (such as engineering), where high precision is not possible. When measuring the digital tachometer to bring close enough to the rotor. Despite the shortcomings, I pleased with the purchase of a digital tachometer.
