Portable Meters The Smart Portable pH and TDS Meters mot only look smart by design, but also feature ingenious gel-filled, double cloth junction electrodes, which are removable and replaceable for easy storage and maintenance. The double cloth junction may be pulled out in 2mm increments as needed, providing a quick fix to clogged junctions, and thereby increasing meter longevity. Roughly the size of a calculator; each meter delivers fast, reliable readings: pH from 0.0 - 14.0 with a +/-.2 accuracy, and TDS from 10 - 1990, with an accuracy of +/- 2%. The pH meter requires a 2 point manual calibration, the TDS meter a 1 point calibration; both are supplied with a 9V battery and a 20 mL sachet of calibration solution. The TDS meter also includes a screwdriver for calibrations. Each meter is backed buy a 2 year warranty. |
