Black Retractable Steel Tape Measure

Black Retractable Steel Tape Measure from China factory

The measuring tape is a commonly used measuring tool in daily life. Usually, steel tape is often seen. It is usually used for construction and decoration. It is also one of the necessary tools for families. It is divided into fiber tape, long stainless steel tape measure from a China factory, waist circumference measure, etc. Luban ruler, Feng Shui ruler, and Wen Gong ruler also belong to steel tape.

Characteristics

Gift rulers are used for advertising. They are divided into steel tape (steel strip) and leather tape (PVC plastic fiber tape). They are generally cute and small. Measuring tape, also known as measuring tools, and 85% of the measuring tape in the world is exported from China.

Principle

The China long stainless steel tape measure from the Manufacturer can be rolled up because there is a spring in it. When the length measuring tape is pulled out, it is actually stretching the length of the scale and the spring. After the measurement, the spring in the tape will automatically shrink, and the scale will shrink back under the action of the spring force, so the tape will automatically roll up as we can see.

Main purpose

The steel tape is the most commonly used measuring instrument for measuring length. It is not only used in factories but also widely used in various industries and even families. According to its application, it can be divided into three types: ordinary steel tape, which is used to measure the length of objects; Sounding steel tape, mainly used to measure the depth of liquid; The steel circumference ruler is engraved with a circumference ruler and a diameter ruler on the ruler belt, which is convenient for measuring the diameter and perimeter of cylindrical objects, so it is mainly used for measuring the diameter and perimeter of objects.

Method of use

1. check the appearance

The ruler surface of the steel tape shall not be uneven or deformed; Both sides of the tape must be smooth without sharp edges and burrs; The width of the long stainless steel tape measure from the China factory shall be uniform.

2. measurement method

(1) Before measurement, check the China long stainless steel tape measure to ensure that it is free to stretch without clamping, and then wipe the tape and workpiece with a dry cloth or cotton yarn.

(2) Measure the dimension. Hook one end of the surface to be measured with a ruler hook, slowly pull out the steel tape, tightly lean the tape against the object to be measured, and keep the eyes in balance with the scale surface of the tape.

Precautions for use and maintenance

(1) The tape of steel tape shall be wiped clean.
