Model 400SBDyC, 400AC

400SBDyC and 400AC are portable tritium survey monitors for measurements as low as 2 µCi/m3 . The OTC electrometer, which measures to below 10 to 16 amperes combines low noise and high zero stability. The 400 series instruments no longer require a front panel manual zero control. Thermally induced zero shifts of the electrometer and associated electronics have been eliminated. The 400AC includes manual and automatic Calibration with tritium gas and a gamma source, improved gamma compensation and noise immunity, along with constant air flow control.
