High Voltage Module

Meets high voltage requirements for Photo-multiplier, GM Counter etc.

Precision high voltage supplies are required in a number of applications pertaining to detection and measurement of radon and radio-activity. A photomultiplier produces a measurable pulse only if a high voltage is applied to its anode and the dynodes. A GM Counter produces a measurable pulse only through the phenomenon of gas multiplication which again necessitates application of high voltage.

Available Model : PSI-HVM-x

Applications

For providing high voltages for Photomultiplier Tube, G.M. Counter, Ionization Chamber, Proportional Counter etc.
