Tension meters are devices used to measure the tension or tightness of a material, such as a wire or cable. They help ensure that the material is neither too loose nor too tight, which can affect performance and safety. These meters are commonly used in various industries, including construction, manufacturing, and telecommunications. There are different types of tension meters, including mechanical and digital models. Mechanical tension meters often use a spring mechanism, while digital ones provide electronic readings for greater accuracy. Both types are essential tools for professionals working with materials like steel cables or fishing lines.
