MULTIPARAMETER WATER QUALITY METER The HI98196 is a waterproof portable logging multiparameter meter that monitors up to 7 different water quality parameters including 5 measured and 2 calculated. The microprocessor based multi-sensor probe allows for the measurement of key parameters including pH, ORP, dissolved oxygen, and temperature. The probe transmits readings digitally to the meter, where data points can be displayed and logged. The use of digital communication allows for noise free transfer of data for up to 100 meters in cable length. The complete system is simple to setup and easy to use.
