The SRM500K is a digital surface resistance test kit designed to test all conductive, anti-static and static dissipative surfaces for electrical resistivity/ resistance according to EOS/ESD, CECC, ANSI, ASTM test procedures. It accurately and quickly measures resistance between two points (RTT) and surface to ground resistance (RTG). Suitable for factory audits and test lab evaluations, the Ohm Metrics SRM500K also measures ambient temperature and humidity.

Features include:

• 10v and 100v range voltage selection
• Automatic zeroing and power shut off
• Two 5 lb disk probes
• Built in resistivity probes
• Carrying case

The SRM500k meets periodic test requirements per Compliance Verification ESD TR53 and conforms to ANSI/EOS/ESD (S4.1, S7.1, S12.1, S2.1).
