Ground Moisture Meter

Calculates soil humidity by measuring the conductivity of the soil between two rod-shaped electrodes that are inserted into the ground. While normally an instrument in the agricultural industry to aid decision making about irrigation, they are also used at soil remediation sites: to prevent hazardous concentrations of contaminated dust in the air, ground moisture meters are used to assess the risk of this happening, enabling operators to prevent dust by spraying water on the remediation site.
