Features: The five-digit length counter is a counter for measuring length and various mechanical transmissions. It is generally used for the recording of the length of the textile, printing and dyeing, plastic film, artificial leather, etc. When the recording length is 1m (or 1 yard), the scroll wheel rotates three times, the counter number shows 1, and so on. However, it cannot count backwards. This counter is equipped with a 0-return mechanism. The 0-return is rotated, and the number of revolutions is all "0", and then the second stage is counted. The counting range is from 0~9999.9 with a maximum counting speed of 200 times/min. Accurate mechanical structure makes the counter can measuring the length more accurately. Specification: Counting Range:0~9999.9 Rotation Counting Ratio:1:3 Maximum Counting Speed:200 times/min Temperature Range:-10~60 Package List: 1 x Counter 2 x Wheel 2 x Screw(In Counter)
