You can return this unit withing 5 days for a full refund minus shippingInfo from web site- The Solution Analyzer measures pH over the entire range of 0 to 14 pH with an accuracy of 0.01 pH. The unit may be operated in the Automatic Temperature Compensation (ATC) mode or with manual temperature compensation using the built-in electronic thermometer to determine solution temperature. The slope control functions from 85 to 105% and allows for compensation of individual pH electrode variance to obtain a linear pH response. CONDUCTIVITY Conductivity measurements can now be made easily as a pH measurement. With one conductivity cell. a dynamic range of 6 decades is achieved allowing one to measure ultra pure water to solutions four times as conductive as sea water. With the flip of a switch the conductivity readings can be automatically temperature compensated between 5 and 45?C or uncompensated. Readings are given in specific conductance thereby eliminating cell constant calculations. A "self-check" mode allows for user to verify proper operation. Total Dissolved Solids (TDS) may also be displayed with scale factors as low as 0.5. MILLIVOLTS Special applications such as Oxidation-Reduction Potentials (ORP) measurements or Ion-Selective Electrode (ISE) analysis requires the use of this feature. The Solution Analyzer provides two mV ranges 0 - to 199.9mV and 0 to 1999mV. Zero control provides 600mV offset. (Three times Full Scale in the most sensitive range). TEMPERATURE A digital thermometer is built into the Solution Analyzer and covers a range of 0 to 100oC.
