67-1 type measuring counterDetailed product description：

The 67-1 type length measuring counter is an improvement on the Z73-5 tachometer, incorporating the advantages of a pull type counter. Suitable for measuring and recording the depth of mine drilling, cable length, and number of winding machine turns.
The 67-1 type length measuring counter is a mechanical transmission automatic carry up recorder. Equipped with a reset mechanism, after stopping the machine, rotate the character axis in the forward direction and reset all numbers to zero.
But it can only rotate the incremental recorder in the forward direction. Equipped with a reset mechanism, after stopping the machine, rotate the character axis in the forward direction and reset all numbers to zero. But it can only rotate in the forward direction for incremental recording, and cannot rotate in the reverse direction for decreasing.

The installation of the 67-1 type length measuring counter should be smooth and concentric with the main body. Otherwise, it will cause the rotating spindle to twist or break, resulting in inaccurate counting or malfunction.
The maximum speed of the 67-1 type length measuring counter is 150 times per minute. If it is too fast, it will damage the internal components.
The inner wheel and gear system are made of special engineering plastics and should not come into contact with high temperatures or thinners. Simply add a little engine oil during normal operation.
