The Desco 19640 Economical Compliance Verification Surface Resistance Checker is 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) of larger surfaces (flooring, mats)
    • 19641 Test Leads
    • 50003 5 Pound Electrodes
• NIST Calibrated
  • Calibrated with accepted procedures and standards traceable to the National Institute of Standards and Technology. For more information on calibration of Desco products, see Calibration
