HANNA HI98194 Portable pH/ ORP/ EC/ /TDS/ Sal./ DO Meter

The HI98194 is a waterproof portable logging multiparameter meter that monitors up to 12 different water quality parameters including 6 measured and 6 calculated. The microprocessor based multi-sensor probe allows for the measurement of key parameters including pH, ORP, conductivity, dissolved oxygen, and temperature. The probe transmits readings digitally to the meter, where data points can be displayed and logged. The complete system is simple to setup and easy to use. The HI98194 is supplied with all necessary accessories and packaged in a durable carrying case.
