In the design of our housings we have paid particular attention to the following:

  • light tightness
  • electrostatic and magnetic screening
  • the use of high quality insultators and components to guarantee stability of components

A voltage divider is supplied with each housing but before ordering please decide on the HV polarity. We recommend positive HV for most applications, except analogue detection where the anode must be close to ground potential and negative HV must be used. Please speak to us if you are unsure of the best voltage divider for your application.
