Our Part No. 19640

Mfr. Model 19640

The Desco 19640 Surface Resistance Checker can be used to determine if a surface is dissipative, conductive, or insulative. The color-coded LEDs quickly provide an exponent range for quick checks of EPA ESD control items. The surface resistance exponent will remain displayed with the test button depressed for data retention.

Automatic test range voltage selection
Portable operation with 9V battery
Flashing LED for low battery
NIST calibrated

Key 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 9V battery
No charging or sourcing of special batteries needed
Flashing LED warns when battery is low
Prevents operator from making bad measurements
Use the same checker to indicate resistance point-to-point (Rtt) of larger surfaces (flooring, mats)
NIST Calibrated

Details

The Desco 19640 Surface Resistance Checker is a portable battery powered checker fitted with built-in parallel electrodes that allow for tests of material surface resistance. This checker is designed for quick checks of surface resistance for ESD control applications in electronics manufacturing or handling environment. The 19640 is equipped with an automatic test voltage selector. The test voltage will switch from 10V to 100V should the measured resistance exceed 1 x 105 ohms. Two banana jacks and an electrode toggle switch allow for the connection of two external 5 pound electrodes (sold separately) that measure surface resistance point to point (Rtt).
