Part # MMF0207  Modulated for use in ionized environments, this pocket-sized fieldmeter takes quick, accurate measurements without continual rezeroing. Switch selectable dual range measures 0 to 1000V at one inch from surface and 0 to 3000V at four inches, or 0 to 10,000 at one inch and 0 to 30,000V at four inches on 10X range. Ideal for manufacturing environments where ionization equipment is in use.

Part# MMF0282  Accuracy has never come so easily or inexpensively. Alternating pulsing beams from two LEDs converge to tell you when the instrument is precisely 1 inch from the target, so its reading is an exact indication of the static field being measured up to +or- 20kV, and up to +or- 80kV with attenuations. It features a hold button to freeze the display. The modulated design guarantees accurate readings even in ionized environments.
