Multiparameter
Multiparameter portable meters have the ability to measure multiple parameters including pH, ORP, dissolved oxygen, conductivity, turbidity, temperature, pressure, and specific ions with the use of either chloride, ammonium or nitrate ISE.
The multiparameter meters can be broken down into three main categories.
pH and EC meters that use an amperometric probe
Multiparameter meters that include pH and EC meters that use an potentiometric probe
Portable meters that measure a single parameter but can be upgraded to measure another parameter
Many meters that measure conductivity allow other units to be displayed including Total Dissolved Solids (TDS), resistivity, and salinity.
