Congratulations on your purchase of the JAQUET hand tachometer.
The JAQUET HO 100 Optical Tachometer uses precision optics and refl ective tape to measure the RPM of rotating devices such as fans and gears.
The JAQUET HM 100 Contact tachometer uses convex and concave attachments to measure RPM. It also has a built-in wheel to measure the linear surface speed
of moving devices such as conveyors and treadmills. Careful use of this tachometer will provide years of reliable service.
The JAQUET HC 100 is a combination set of the both HO 100 and HM 100 tachometers.
