Digital Surface Resistivity Meter

The model SRM-04 Digital Surface Resistivity Meter is a portable, versatile, instrument design to accurately measure the resistance between two points, surface to ground and surface resistivity accordance with EOS/ESD association standard S-4.1 in addition, the meter measures & displays ambient temperature & relative humidity.

The model SRM-04 Digital Surface Resistivity Meter (includes Testing & Measuring Probes) is designed to make measurements of Work surface, floors, foot wears, garments, workstations & operator chairs etc..


Alpha numeric display Row 1: Ambient temperature and relative humidity are displayed during the meter ON condition.

Alpha numeric display Row 2: Provides easy to read measurements directly from the meter include exponents. No interpretations or calculations are required.

Power ON Button: Activates electrical power to the meter.

Power OFF Button: Deactivates electrical power to the meter.

Battery Status Button: To know the battery power in percentage.

Surface Resistivity: Parallel stainless steel electrodes provide for measurement of surface resistivity or when quick testing without the use of Testing & Measuring Probes is desired.
