For difficult access, nothing beats the REED DT-1236L laser tachometer. This unit also measures linear speeds & contact RPM measurement. The non contact measurement can be made with reflective tape on the shaft, or white paint for close range. Contact measurements use a rubber cone (shaft centre drilling) or rubber rimmed wheels for linear speed. These components are replaceable separately. For fixed installations Lutron makes a panel mount 48×96 digital indicator for inductive or optical pickups.
