Extech Tachometers Editorial Review
Extech 461920 Mini Laser Photo Tachometer and Counter, 99999 RPM features both non-contact RPM measurement and a counter mode, making it highly versatile for various applications. Users find the non-contact RPM measurement especially convenient as it allows for accurate speeds without touching the shaft, which is beneficial for delicate parts. The 5-digit backlit LCD display is another highlight, as it remains clear and easy to read even in lower light conditions. However, a common critique is its dependency on reflective tape for accurate readings, which may lead to inconsistencies on uneven surfaces. Despite this minor setback, the device offers great portability and usability, making it a favored choice for both professionals and DIY enthusiasts.
