ESDA toner and Ozone reduction workstation

TORnado SF91 Toner and Ozone reduction system for ESDA workplaces.

For many years the use of Electrostatic Surface Detection Systems (ESDs, as Foster + Freeman's ESDA) is considered a standard in document examination.

Along with Ozone from the Corona, during the development process, Toner particulates are also released into the environment, especially when using the quentitatively better Cascade-Developer method. Whilst this is still the optimum procedure for development of indented writing, local health and safety regulations may have charged over the years. Many larger laboratories already use exhaust cabinets. However, smaller labs and many private document examiners do not have access to such exhaust systems.

Attestor Forensics developed the Toner Particulate and Ozone Reduction System TORnado SF91 especially for this type of user.


Key Features:

  • Reduces Ozone exposure
  • Reduction of dust exposure
  • Touch panel control
  • Particulate filter
  • Integrated illumination source
