The Model 1501 surface resistance meter is a hand-held, lightweight, auto ranging surface resistance tester. Built-in electrodes with conductive rubber make good contact with the object under test. Measured values are displayed on an LCD dot matrix module and can be stored in the internal memory. Each measurement includes the current temperature and relative humidity. Model 1501 software (included) provides easy access, display and export of data collected. Data can be exported to a .CSV file or displayed as an HTML report in an easy to read chart for data comparison. Appropriate electrodes can be externally onnected for tests according to IEC 61340-4-1, IEC 61340-2-3 and IEC 61340-4-5, ANSI/ESD S4.1-2006, ANSI/ESD STM11.11-2006, ANSI/ESD STM11.12-2007, ANSI/ESD STM11.13-2004, ANSI/ESD 12.1-2006, ANSI/ESD STM 97.1-2006.
