Field-installation Type Electric Conductivity Meter (Four-Wire Transmission, For High-concentration)

HE-200H connects conductivity sensor (FES-12X/2XX/310 Series) and measures conductivity and temperature in the sample water. It can be used not only for measurement of electrical conductivity in aqueous solution, but also for concentration adjustment and rinse monitoring of CIP, etc., as well as for concentration monitor of process.
