It can easily and accurately measure narrow and deep positions that are difficult to measure with ordinary indicators.
The unique new structure of Sanfeng Company is used to suppress damage to the grip part of the measuring needle, prevent deterioration of the sensitivity and tracking performance (smoothness) of the measuring needle.
The pointer and hard alloy measuring needle have anti magnetism and are not affected by it in a magnetic environment. In addition, there are models equipped with ruby (non-magnetic) measuring needles. Ruby measuring needles have several times higher wear resistance than hard alloys, and because they are non-conductive materials, they can be safely used on electric discharge machines.
The dial uses a universal font, which greatly improves visibility by modifying the relationship between dial color, pointer, and scale thickness. The length of the measuring needle is displayed with illustrations on the scale plate.
The surface of the watch cover is an anti glare flat type. And it is coated with a layer that inhibits scratching, dirt, and reflection.
The integrated structure of the outer shell and the watch cover can prevent cutting fluid and oil stains from penetrating through the dial and gaps. (However, it is not a waterproof specification)
According to various purposes, there are five types to choose from: horizontal, inclined, vertical, parallel, and universal.
Finished product inspection is based on JISB7533:2015 * 1. To ensure accuracy, the horizontal, inclined, and vertical types are tested with the indicator panel facing upwards, while the parallel type is tested with the indicator panel facing upright
