The Hanna HI99301 is a rugged, waterproof (IP67) portable meter that measures conductivity, TDS, and temperature in the high range — EC from 0.00 to 20.00 mS/cm and TDS from 0.00 to 10.00 ppt. Its compact body fits in the palm of your hand, and the bottom probe connection keeps the cable out of the way.
