Surveying Instrument Equipment Stonex R3 Total Station
LIMITLESS DISTANCE MEASUREMENTS
By using a digital phase laser ranging technology, R20 guarantees high accuracy measurements: 1000 m or 600 m (depending on the model) in reflectorless mode and up to 5000 m using a single prism, with millimeter accuracy.
FAST, ACCURATE, RELIABLE
Measuring distances with high angular accuracy make any job extremely cost effective and reliable. The wide range of application software allows to complete the Surveyor’s tasks directly in the field.
ONE DAY OF CONTINUOUS FIELD WORK
Thanks to the low power consumption circuit design R20 gives the opportunity to continuously work for more than 22 hours.
TEMPERATURE PRESSURE SENSORS
Temperature and pressure changes have a negative impact on the accuracy of distance measurements. R20 monitors the changes and automatically adjusts the distance calculations.
