Presentation

Model A603 is a tilt measurement system for geophysical applications requiring high accuracy and stability. The A603 system incorporates two high-precision electrolytic sensing elements mounted perpendicularly, enabling detection of minute movements in the X and Y axes (resolution < 2.5 nrad). 2 low-pass filter gain and time constant values are selectable by jumper.
