All units feature a direct-read digital high voltage display.
Various tubes are available to suit a variety of detection needs, and are easily installed within minutes. Users of the 810 digital detector may upgrade it at any time to selectively perform analog detection with the addition of an optional analog circuit module. Model 814 is a combined digital and analog detection system, with all of the electronics and controls of the 810 plus an analog type detector system, with controls for gain, time constant, offset and output mode. This mode is set by an internal jumper. All models share the same internal high voltage power supply and come with a separate line voltage power supply.
