Is this able to measure DO, pH, ORP, EC simultaneously, or does the user have to change sensors for each parameter?
Hanna HI98194 Multiparameter pH/EC/TDS/Salinity/DO/Pressure/ Temperature Waterproof Meter
How many sensors can be plugged into the unit at a time? Will it hold all three (pH/ORP; DO; EC) at once to allow simultaneous reading of these parameters? The meter will be used to measure groundwater samples from monitoring wells, with typical sample volumes of 250-500 ml.
