Technical Specs



Battery Operated. Wide Range. Digital.

The digital, battery operated PRS-801B Resistance Instrument accurately measures resistance point-to-point(Rtt), surface to ground (Rtg) and surface resistivity over the range of 0.01 ohms to 2.0×1014 ohms.Its constant test voltage system is extremely stable at 10 volts and 100 volts.


Complies to ANSI/ESD Standards

The PRS-801B will measure resistance in accordance with ESD Association documents:

  • ESD TR53
  • ANSI/ESD S4.1
  • ANSI/ESD S7.1
  • ANSI/ESD STM97.1


Repeatable Measurements

The Surface Resistance System Kit includes 2 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.

High Quality Test Leads

Prostat’s 10 foot test leads supplied with each PRS-801B consist of hundreds of fine strands of copper that offer flexibility and accuracy. The outer insulation of each test lead is high grade silicon with an extremely high resistance to minimize measurement errors. These leads are designed for convenient audit measurements in the manufacturing environment up to 1.00×1012 Ω. The 30 inch high performance test lead harness is designed for PRS-801B precision high resistance measurements in the 1011 to 1014 range. It includes a shielded (-) negative test lead for accuracy and minimum electrical interference from personnel and equipment. The shield is connected directly to the PRS-801B instrument reference and fixture ground.

Download Data with Connect 2.0 Utility

The PRS-801B has the capability of recording up to 999 measurements into memory. With the use of the included Utility Software and USB adapter, it can download the stored data to your Excel® Spreadsheet program. This minimizes transposition mistakes and speeds up precision measurements. The PRS-801B connects to your computer’s USB port and quickly transfers the data into Excel®.
