The Rabun Labs’ Model GM/MS is used to monitor and automatically maintain the resistivity of electrical grounding systems. This is accomplished by sensing soil resistivity in the area where the grounding system is installed and activating a solenoid-operated valve when the soil resistivity rises above a pre-set limit. The valve is connected to a spray head or “soaker” hose that shuts off automatically.
