The NWI NETH503 is a 5″ digital theodolite that combines high-precision optics with intuitive electronic angle measurement. Its 30x erect-image telescope, 45 mm effective aperture, and 1°20′ field of view deliver sharp, bright target images, while the photoelectric incremental encoder captures horizontal and vertical angles with 5″ accuracy and 5″ resolution. Dual, back-lit LCD displays on both sides of the instrument make angle readouts easy to see from any operating position, reducing setup time and minimizing transcription errors.
Built for tough field conditions, the NETH503 includes an optical plummet for quick centering over points, sensitive plate and circular vials for fine leveling. Powered by either rechargeable or alkaline batteries, it offers up to 40 working hours and weighs just 10 lbs for easy transport. Backed by a 3-year manufacturer’s warranty, it’s a dependable choice for surveyors, contractors, and engineers who need consistent, high-precision angle measurements.
