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 Panel-Mount Tachometers with Certificate of Calibration
Accurate to within ±0.001% of reading, these tachometers come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. Install in a convenient location and measure speed remotely using a sensor (sold separately). Use the buttons on the front panel to program the unit.
Proximity sensor detects moving metal objects, such as gear teeth and fan blades and can be used in dirty and wet environments. Maximum measuring distance is 0.2" from a 1/2" minimum size metal target.
Magnetic sensor has a maximum measuring distance of 0.005" from a 0.1" minimum size ferrous metal target.
Optical sensor performs best in clean environments and works at up to a 45° angle from reflective tape.
