Tension meters are devices used to measure the tension or force exerted on a material, such as a wire or cable. They are commonly used in various industries, including construction, manufacturing, and telecommunications, to ensure that materials are under the correct amount of tension for safety and performance. These meters can be mechanical or digital, providing readings in units like pounds or newtons. Some tension meters are portable, allowing for easy use in the field, while others are designed for stationary applications. Accurate tension measurement is crucial for maintaining the integrity of structures and equipment, such as bridges, cranes, and communication lines.
