Steel Long Tape

A steel long tape is a measuring tool used in construction, surveying, and various other applications to accurately determine distances. It typically consists of a flexible, steel tape encased in a durable housing with a mechanism for easy winding and unwinding. The tape is marked with precise measurements, usually in feet or meters, allowing users to measure lengths with a high degree of accuracy. The steel construction provides durability and resistance to stretching, making it suitable for demanding outdoor environments. Steel long tapes are commonly used by professionals in fields such as carpentry, architecture, civil engineering, and land surveying.  

Vernier Caliper

A Vernier caliper is a precision measuring instrument used to measure dimensions with high accuracy, especially in mechanics and engineering. It consists of a main scale and a sliding Vernier scale, allowing users to take precise measurements of lengths, diameters, and depths. The main scale is graduated in millimeters or inches, while the Vernier scale provides additional resolution, allowing measurements to be taken to a fraction of the smallest division on the main scale. This dual-scale design enhances the precision of measurements, making Vernier calipers valuable tools in various scientific and technical applications.
