The RT-1 is a high sensitivity, portable, hand-held magnetic susceptibility meter with digital and analogue display. It can store over 9800 readings, and display immediate and stored readings as SI or CGS. It is microprocessor (flash ROM) controlled, allowing flexibility in display, auto-ranging, and auto-calibration in free air.

The RT-1 has a bluetooth interface to transfer stored readings to a computer. The data outputs as an ASCII file and includes the magnetic susceptibility reading and any event flags.

The RT-1 includes a built-in magnetic susceptibility test pad. This enables you to check calibration easily, anywhere and at any time.
