Radiation Resistant Servo-Inclinometer TS2R Model

This Servo-Inclinometer was designed to operate in intense radiation environment. It was originally developed in cooperation with Ontario-Hydro of Canada to monitor the fuelling machines of nuclear power-stations, where it is exposed to radiation over extended periods of time.
