Unit shines a beam of light which reflects off self-adhesive tabs to give readings of 10 to 99,999 revolutions per minute. Resolution is 0.1 below 1000 and 1 above. Accuracy is ±1 RPM or 0.05%. Utilizes a precision quartz crystal for an accurate time base. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from the manufacturer’s ISO 17025 calibration laboratory accredited by A2LA.
