High-Accuracy Digital Contact
Tachometers with Certificate of Calibration
Accurate to within ±0.006% of reading, these tachometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. Contact tachometers come in direct contact with the object measured and are an excellent choice for dirty and dusty environments.
Note: Units are calibrated to work with either a 6" or 12" circumference speed wheel but not both.
Choose tachometer with LCD for use in bright light.
Choose tachometers with LED for use in dimly lit areas.

High-Accuracy Contact/Noncontact Tachometers
Accurate to within ±0.006% of reading. Switch these tachometers from contact to noncontact mode by attaching the included adapter. They come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. All have a 1/4”-20 female threaded bushing for tripod mounting.
Choose tachometers with LCD for use in bright light.
Choose tachometers with LED for use in dimly lit areas.
Tips measure the rotational speed of shafts and other spinning objects. Tips for flat-end surfaces are often used with pulleys and circular saws. They have a concave surface to fit flush over bumps, such as screw heads. Tips for shafts with center hole are cone-shaped, so they’ll fit the inner diameter of different hole sizes.
Speed wheels measure the length and speed of conveyor belts, bolts of fabric, and material on spools. They have a grooved edge to fit over wire, cable, and cords.
