Traceable Photo Tachometer with Calibration

Four AA alkaline batteries, self-adhesive reflecting tabs, internal light, hard-sided carrying case, and NIST-traceable calibration certificate with data.

主要特点

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.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.
