Dual Input Digital In-Line TDS Total Dissolved Solids Water Quality Test Meter

Total dissolved solids (TDS) are the total weight of all solids (minerals, salts, and metals) that are dissolved in a given volume of water, expressed in parts per million (PPM). The higher the TDS level, the greater the probability of harmful contaminants. Get accurate readings and learn more about your water quality and hardness with this dual input digital TDS Total Dissolved Solids Meter. The TDS measures water hardness in parts per million, ppm, by measuring electrical conductivity (ec). Displays total dissolved solids from 0-1999 PPM. The dual input lets you compare the TDS of two samples, ideal for installing on the input and output of a water filter to compare the total dissolved solids coming into and out of the filter.  This TDS meter includes a mounting bracket for installation on a wall or bulkhead. It can be calibrated using a standard calibration solution by turning the trimpot on the side of the case with a small screwdriver (included).  This TDS Total Dissolved Solids m
