Surface Resistance Testers

99105

• Accurately measures Rp or Rg (requires Item 99107) for quick checks, factory audits, or test lab evaluation of product.
  Versatile tool measuring surface resistance as exponent number illuminates immediately, but designed to measure for full 15 second electrification period and exceeds accuracy requirements of EN 61340-5-1 Annex A.
• Meter measures ambient temperature and relative humidity.
  Available when required for test records.
• Color coded LED and digital LCD read-out.
  Easy to read, no interpretation needed; can easily be used for quick go/no go checks.
• Automatic Test Range Voltage Selection.
  In accordance with ESD Association standard, meter will test at 10 volts and automatically switch to 100 volts if over 10E5 ohms.
• Surface resistance exponent always displayed if test button is depressed.
  Quickly and continuously provides exponent of resistance measurement which is often all that is required for quick checks or factory periodic tests.
• LED identifies function and type of measurement displayed by LCD.
  Over electrification period cycles through temperature in °F then °C, then Relative Humidity, and then mantissa of resistance.
• Portable operating on just two alkaline AA batteries.
  Very versatile requiring no plugging in or sourcing special batteries.
• "1____" on the LCD displays indicates Overrange.
  Quickly identify insulative surfaces as the reading exceeds the display capabilities.
• Flashing LED warns when battery is low.
  Alerts you when batteries need changing.
• 10 Volt button feature.
  Can override automatic voltage selection and perform test at 10 V.
• Optional Resistivity Attachment (Item 99107).
  To be able to quickly and accurately measure resistivity.
