Review on Non Contact Tachometer NIST Traceable Calibration Certificate by Narendra Thapa

The tool itself is fine! such as construction and finish, and also appears to be fairly accurate compared to an industrial grade angle sensor. Only less is ok! Aspects are the application of the serial number label which was partially taped to the back of the case and the second problem with closing and locking the tool box, one of the two locks does not work properly. Verdict: For the tool itself, I'm giving it a five-star rating, but given some design flaws throughout the kit, the overall rating is four stars.
