Measure nutrients, salts, and other dissolved solids. As your membranes age, the TDS (total dissolved solids) of the product water will gradually increase. A hydrotester will measu re the water quality in terms of how much salt is being removed. It is common to want to change membranes when the system gets to about 750-800ppm (parts per million) of TDS. Four modes: EC: mS, uS, TDS: ppt, ppm. Fast and accurate, +/-2% Simple to use Digital calibration Water resistant Durable Auto shut off after five minutes EC to TDS conversion factor: NaCl (0.5 avg) Auto temperature compensation (ATC) Hold function Power: 3 x 1.5V (357A) Battery life: approximately 2 years Dimensions: Length 153mm (6.0″), Width 32mm (1.3″), Height 18mm (0.7″) Show more
