Technical Specs


Accurate. Digital. Portable.

The PRS-812B Surface Resistance Ohmmeter is a wide range portable constant voltage resistance instrument designed for making point-to-point and resistance to ground measurements. The PRS-812B is a reliable instrument withoutstanding accuracy and performance.The PRS-812B is extremely fast with a constant test voltage system that is incredibly stable and consistent. The PRS-812B is a lightweight solution to a portable instrument with capabilities of storing up to 120 data points.

Ideal in a Variety of Applications

The PRS-812B’s accurate wide range of 0.1 to 1.00×1012 ohms offers exceptional flexibility in measurement applications. Combined with the included Conductive Rubber Electrodes, you can measurement resistance on the following:

  • ESD Flooring
  • ESD Worksurface
  • ESD Carts
  • Shelving
  • ESD Gloves
  • Furniture


Repeatable Measurements

The Surface Resistance System Kit includes 2 each PRS-801W Rubber Electrodes which are precision milled resistance probes with conductive rubber pad for use when making point-to-point or point-to-ground resistance measurements. Used for qualifying or testing ESD floors, worksurfaces, floor mats or any flat object, the probes produces repeatable measurements in accordance with ESD Association standards.
