Desco 19640 Surface Resistance Tester

• 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
• NIST Calibrated
• Made in the United States of America
