The Model TAC-L Portable Digital Tachometer measures rotational speed either
by contacting a rotatable head to the shaft of the object or by using a photo sensor
to detect the reections from the laser. The housing is made of a strong, lightweight
ABS plastic housing, which is designed to comfortably t in the hand of the user.
Supplied with this model are 3 contact rotational heads, a contact surface wheel, and
a protective carrying case.
