Reflectorless Total Station 822R3
Reflectorless type
Total station with SD card.
Advanced technological features
built in a compact body
for Precision accuracy.
• Absolute Encoding - The 822R3 is equipped with absolute encoders, which provide high accuracy and reliability. No need to reset the system for 0 indexing eliminating manual initialization.
• Dual Axis Compensation - Vertical and horizontal angles are compensated by dual axis compensator that detects tilt in both directions, ensuring enhanced reliability.
• Control Panel - Backlit 6 lines LCD Display & Alphanumeric keyboard with single touch button functions for easy input, access to information and control of main parameters such as EDM mode including reflectorless or prism.
• Rechargeable Batteries - The 822R3 Total Station is provided with 2 x Rechargeable Ni-H Batteries to ensure that the unit can be used continuously at work site without having to stop & recharge.
• Large Internal Memory - Storage capacity of up to 16000 data points. In addition, data can be sorted into different jobsite files in the extended memory with use of the SD card (upto 200,000 points).
• Water & Dust Proof - All significant part are protected by tight rubber rings. With Waterproof Grade IP54, you are free to operate the unit in a desert or rain.
• Temperature & Pressure Sensors - Takes surrounding temperature and pressure measurement automatically to implement auto compensation for high accuracy.
