D-2 Inc.”s line of continuous in-line and laboratory sensors are designed to measure the conductivity of liquids in the 0-2000 pS/M and 0–200,000 pS/M range. The JF-1A-MR multi-range, in-line conductivity sensor is Ex certified, while the JF-1A-HH-CM handheld sensors (pictured here) meet the needs of laboratory measurement. According to D-2, the sensors are capable of accurately determining the conductivity of a fluid chemical, helping to limit the hazard of a possible static discharge explosion during fluid transfer handling operations.
