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.

Contact/Noncontact Tachometers

Capture high-speed readings from a distance in noncontact mode or use the speed wheel to switch to contact mode. This tachometer comes with a calibration certificate traceable to NIST that states it has passed a test for accuracy. It has a 1/4"-20 female threaded bushing for tripod mounting.
BNC cable (sold separately) sends signals from the tachometer to a data collector.
