As a note on the axis of rotation marked reflective film, reflective film will align tachometer, click the measure button, you can high-precision direct reading display 30 ~ 50,000 r / min speed. In the internal memory 10 of the measurement results can be stored. Further, if the number of the reflection film paste to the shaft 8 as a reflection film paste, it can be detected at very low speed 4 r / min. Tachometer housing through ergonomic design, easy to use, can be put into the chest pocket, thin and compact. Because it is non-contact measurement by light, and therefore extremely safe, but do not worry about adding strength and load on a rotating body, can safely be measured. Features · 129 × 62 × 26.4mm, 90g of small, lightweight non-contact measurement Intuitive and easy to read large LCD display (letter height 10.5mm) · speed range as large as 30 ~ 50,000 r / min (using a reflection When the film) · equipped with memory for easy confirmation measurements · In a few reflective markers attached to the rotating shaft can be measured at very low speed, can be measured to 4r/min Overview Specifications Speed ??range measurement range reflective diaphragm number (input signal number) Contact Manager Hou 18210710916 30 ~ 50,000 r / min 1 15 ~ 25,000 r / min 2 10 ~ 16,667 r / min 3 8 ~ 12,500 r / min 4 5 ~ 8,333 r / min 6 4 ~ 6,250 r / min 8 measurements Unit 1 r / min detection distance 20 ~ 300 mm display digits five 7-segment LCD display time of 1 second automatic measurements show repeated (but 30 ~ 60r/min when repeated automatically every 2 seconds) measurement accuracy of 30 to 12,499 Within less than r / min ± 1 r / min 12,500 ~ 24,999 r / min ± 2 r / min 25,000 ~ 50,000 r / min ± 4r/min memory function within the measurement data 10 may be present in the non-volatile memory (power OFF can keep a record of value) to keep the data for 30 seconds after the measurement function measurement is completed, the power automatically turns off after 30 seconds pulse number setting function 1,2,3,4,6,8 P / R (switch) * correspondence reflective markers on the number (the number of the input signal) speed range overflow display "OVER" letters (when the measured value exceeds the display range)
