Z73-5 type tachometerDetailed product description：

The Z73-5 tachometer is used for measuring length and various machine rotary recorders, generally suitable for measuring and recording mining drilling depth, cable volume length, winding machine turns, and other measurements.
This table is a five digit number. The rotation direction of the shaft can be clockwise or counterclockwise, with clockwise rotation being incremental and counterclockwise rotation being decreasing. The highest recorded number is 99999, with the first digit being 1/10 of the shaft's rotation. After one rotation of the shaft, it can automatically carry forward.

The Z73-5 tachometer is equipped with a zeroing mechanism. Once a certain number of readings are recorded, the press handle can be pushed to reset all readings, and then a second recording can be made.
When installing the Z73-5 tachometer, attention should be paid to balance, and the contact with the host should be concentric, otherwise it will cause the rotating spindle to twist or break, resulting in inaccurate counting or malfunction.

The maximum speed of the Z73-5 tachometer is 350 revolutions per minute. If it is too fast, it may cause damage to the components.
When resetting, the head position must be turned within the window cover range and cannot be reset during rotation.
The internal wheels and gears in this table are made of special engineering plastics and should not come into contact with high temperatures or flammable gases. The bearings must be regularly oiled.
