Subtype: pH/EC/TDS
The Hanna pH EC TDS Meter with F.S.T. Technology accurately conducts each respective test in one handy unit. The meter ranges are: pH from 0.0 to 14.0 with a 0.1 resolution, EC from 0.00 to 4.00 with 0.01 resolution, and TDS from 0 to 1990 ppm with a 1 ppm resolution. The accuracy is ±0.1 for pH; EC and TDS have an accuracy of ±2%. This meter features a fast-response probe, automatic temperature compensation, calibration knobs for one-point manual calibration and F.S.T. Technology that informs the user of a possible anomaly (such as a cable short circuit) that needs to be corrected by displaying a pH value close to 4 rather than 7, as is the case with similar instruments. There is also a “check” button with corresponding LED lights to indicate potential probe and electrode problems. The meter comes in a storage case with calibration, test and cleaning solutions; 9V battery; and detailed instructions.
