The Trek® 706B electrostatic voltmeter provides switch-selectable measurement ranges of 0 to +1 kV or 0 to -1 kV and employs an easy to read 3.5-digit, liquid crystal display. Accurate electrostatic measurements can be performed over a probe-to-test surface spacing of 1 to 5 mm. And probe-to-surface spacing can vary during use thanks to the 706B's voltage-nulling technique.

The instrument's probe design provides low noise and drift performance even in the presence of contaminating toner particles or under high humidity and temperature conditions. The Trek 706B is lightweight, battery-operated, and packaged in a rugged enclosure that provides a convenient probe storage area.
