ACL 390

Surface Resistance Meter

This durable and lightweight handheld meter measures both Surface Resistivity between two points Rtt and Resistance to Ground Rtg . Test Range is from 103 to 1012 ohms. Meter automatically generates a 10v or 100v test voltage for a 9 volt battery with results shown through a multi-colored LED display. Meter can be used with the built-in parallel stainless steel electrodes or with optional external electrodes.
• Meter includes ground cord and case.
• Optional 5 pound weigh kit is avaliable.
• Lightweight and durable
