The Rugged Conductivity/Level/Temperature Meter accurately measures conductivity, water level, and temperature. This ASME-certified tape is ideal for taking conductivity and temperature profiles in boreholes, wells, and open bodies of water. The probe uses a four-electrode system that reduces corrosion, giving you more accurate, reproducible readings. The tape is constructed of high-tensile steel, coated in medium-density polyethylene for maximum durability.
