The Milwaukee 3 in 1 meter is the Cadillac of meters. It measures pH, EC and TDS (PPM) with one probe. PH resolution is measured from 1-14, EC from 0-10 and TDS from 0-5000. Uses one 9 volt battery (included). Two year warranty on the meter, and a 6 month warranty on the probe. Replacement probes are also available. Calibration solutions are available below. You can use either the 1.413 solution for EC or the 1500 TDS solution. You do not need both because when you calibrate EC, the TDS is also calibrated, and vice-versa. Calibration solutions for the 3 in 1 come in a box of 25 sachets.
