The HI 98311 waterproof tester has a dual-level LCD that displays EC or TDS and °C or °F. At startup, DiST performs a self check and then displays the remaining battery level to assure proper working condition. It also features a stability indicator and hold feature to prompt the user when to take the reading. The stainless steel temperature probe makes for faster and more precise temperature measurement. Calibration and temperature compensation is automatic. The graphite electrode provides the greatest possible accuracy as it cannot be contaminated by salt deposits in the solution!

The HI 98311 is supplied complete with protective cap, batteries and instructions. For calibration we suggest HI 7031M.
