Electronic Theodolites — Surveying & Geomatics Equipment
Where distances come from tape or GNSS, an electronic theodolite remains the simplest way to turn and read angles with no reading errors. We offer 2-second and 5-second digital theodolites, a laser version that projects the line of sight, a 10-second teaching model, a dual-axis compensated 1-second instrument and a gyro theodolite for tunnel orientation. Angle class, compensator and plummet type decide the choice. Calibration usually follows ISO 17123-3, with DIN 18723-3 still cited on older contracts.

How to specify
- A vertical compensator is worth paying for on any work involving steep sights.
- Laser plummets are faster over pegs; optical plummets work in bright sun.
- Universities usually buy 10″ models in sets of ten with matching tripods.
