Digi-Sense 98767-04 Traceable Photo Tachometer with NIST

98767-04 Includes Only:

• Traceable Photo Tachometer with Calibration
• Four AA alkaline batteries
• Self-adhesive reflecting tabs
• Internal light
• Hard-sided carrying case
• NIST-traceable calibration certificate with data.

Features:

• Measure RPM or surface speeds from 2 to 78"
• Obtain speed measurements in a second
• Traceable® model number 4060

This noncontact tachometer features a laser to aim a precision beam on the object's speed being measured, and a quartz crystal provides an accurate time base. Use the memory feature to recall minimum, maximum, and last reading on the 5-digit, 3/8" height LCD.

The integrated laser beam reflects off self-adhesive tabs (included) to give readings from 10 to 99,999 RPM-ideal for speed measurements of centrifuges, motors, and stirrers.
