Cast Iron Polished Vernier Transit Theodolite, Color : Silver

A Vernier Transit Theodolite is a precision optical instrument used in surveying and civil engineering to measure horizontal and vertical angles.It features a telescope mounted on a rotating base, allowing for precise angular measurements. Below are the typical specifications and features of such instruments:​

• Magnification: Typically ranges from 18x to 30x. ​

• Objective Aperture: Commonly 38 mm to 40 mm, ensuring sufficient light gathering for clear observations. ​

• Field of View: Approximately 2.6 meters at 100 meters, facilitating a broad viewing angle. ​
  

• Vernier Reading: Commonly 10" or 20" (seconds of arc), indicating the instrument's precision. ​
  

• Plate Level Sensitivity: Approximately 45" per 2 mm, ensuring accurate leveling. ​
  

• Telescope Length: Typically about 210 mm, providing a balance between portability and functionality. ​
  

• Weight: Varies between 4.8 kg to 15 kg, depending on the model and materials used. ​
  

• Clamps and Tangent Screws: Enable coarse and fine adjustments of the instrument's orientation.​

• Tripod: Provides a stable platform for the theodolite.​
