A level is a precision instrument, and proper storage can effectively extend its lifespan and maintain measurement accuracy.

Leveling instruments possess high-precision measurement capabilities.

Theodolites are widely used in building construction layout, road and bridge construction positioning, and structural installation surveying.

The primary functions of a theodolite are angle measurement and spatial positioning, making it an indispensable tool in basic surveying and enginee...

Angle measurement accuracy is the most crucial indicator of a theodolite, typically expressed in seconds (″), such as 2″, 5″, 10″, etc.

These instruments read angles through an optical scale and vernier system, relying on manual observation and readings to complete measurements.

The loading system is a crucial component in mechanical testing, primarily used to apply compressive, tensile, or bending forces to concrete specim...
