19640 – Surface Resistance Checker

Features

• Economical Compliance Verification Surface Resistance Checker

Used for determining if a surface is dissipative, conductive, or insulative

• Color Coded LEDs
  Quickly provides exponent range for quick checks of EPA ESD control items
• Automatic Test Range Voltage Selection Per Compliance Verification ESD TR53
  Starts tests at 10 volts and automatically switches to 100 volts if the measurement is over 10E5 ohms
• Once Reading is Finalized, the Surface Resistance Exponent Will Remain Displayed as Long as Test Button is Depressed
  Provides exponent range of resistance measurement which is often all that is required for determining if a material is intended for an ESD Protected Area
• Portable Operation With 9 Volt Battery
  No charging or sourcing of special batteries needed
• Flashing LED Warns When Battery Is Low
  Prevents operator from making bad measurements
• Optional Five Pound Electrodes and Leads For Resistance Measurements
  Use the same checker to indicate resistance point-to-point (Rtt) and resistance to ground (Rtg) of larger surfaces (flooring, mats)
