Traceable Photo/Contact Tachometer with Calibration

hard-sided carrying case, self-adhesive reflecting tabs, internal light, cone for rpm, wheel for rpm, wheel for surface speeds, four AA batteries, and NIST-traceable calibration certificate with data.

主要特点

Obtain RPM and surface speed with the included cone and wheel tip, or make touchless measurements with the integrated light—both readings from one tachometer. This two-in-one meter employs a precision quartz crystal for an accurate time base.

Noncontact measurements can be taken up to a foot away by using reflective tape (included) to cover a range of 0.1 to 99,999 RPM. Contact readings can be obtained with either the cone or wheel tips (included) to span a range of 0.1 to 19,999 RPM.

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.
