Product Overview
THETA Digital
Key Features
Instrument Design
- Classical orthogonal sensor topology with sensor axes pointing in the three cardinal directions.
- Fine pitched adjustable feet manufactured from brass.
- All sensor components are made of non-magnetic materials, minimizing noise induced by outside magntic fields
