Portable Multiparameter Water Quality Meteris equipped with a backlit LCD display. It is suitable for measuring the PH, ORP, ion concentration, TDS, salinity, conductivity, resistivity, and dissolved oxygen. Automatic electrode recognition shows the pH slope and offset. Relative and absolute millivolt modes provide reliable ORP measurements. Data can be transferred easily to computer by using USB interphase. It is reliable, user friendly, applicable for outdoor measurements.
