Contact/Non-Contact Digital Tachometer
The Dwyer TAC-L Portable Digital Tachometer measures rotational speed either by contacting a rotatable head to the shaft of the object or using a photosensor to detect the reflections from the laser. The laser target can record from a distance of up to 20 inches and gives a more accurate measurement than LED targeting. The Dwyer TAC-L features a large LCD with a backlight for use in dark areas. This tachometer is made of a strong, lightweight ABS plastic housing, which is designed to comfortably fit in the hand of the user. Supplied with this model are 3 contact rotational heads, a contact surface wheel, and a protective carrying case.
