To convert from EC to ppm, simply multiply EC by the ppm scale required, e.g. 2.5EC x 500scale ppm = 1250ppm. The two scales Bluelab use are; 700ppm and 500ppm scale. There are many ppm scales around, but these two are most common. TDS is Total Dissolved Solids. This is the 500ppm scale.

PPM – Parts Per Million. For every million parts water, the PPM tells you how many parts of Electro-Conductivity (EC) or Conductivity Factor (cF) can be expressed as either milliSiemens (mS), cF, or parts per million (PPM) 1 mS = 10cF = 700ppm.

1.0, 500 PPM, 700 + 500 ppm correspond to 1000 μS / cm or 1 EC. When using a NPK meter, the relation between TDS and electrical changes to the below stated value. + 700 ppm mg/l to ppm to tds to mmol/l to meq to EC to μS (microSiemens) + 700 ppm correspond to 1000 μS / cm or 1 EC. The EC determination can be done in different If EC meters are not reading correctly than the grower is misinformed as to the strength of the nutrient solution which 1 mS = 700 ppm : 2.76 mS = 1932 ppm.

Along with PPM levels, the pH also plays a vital role. Though you are taking the PPM reading accordingly, some particles can be harmful if the pH level is not up to the mark. Suppose at any system, the expected PPM level is 700 and its reading is showing you the same with a pH level of 4.5.

I'm not too familiar with the nomenclature and people seem to talk about EC in terms of 0.X - whereas my EC meter gives me a ~700 There are three conversion factors which various manufacturers use for displaying ppm's USA 1 ms/cm (EC 1.0 or CF 10) = 500 ppm European 1 ms/cm (EC 1.0 or CF 10) = 640 ppm Australian 1 ms/cm (EC 1.0 or CF 10) = 700 ppm For example, Hanna, Milwaukee 1 ms/cm (EC 1.0 or CF 10) = 500 ppm Eutech 1 ms/cm (EC 1.0 or CF 10) = 640 ppm EC X 700 = PPM 700; Example: 1.00 EC = 700 ppm.

Most inexpensive meters will only display PPM and usually in the 500 scale. The true ppm of a solution can only be determined by a chemical analysis, ppm cannot be measured by an EC meter. The conversion from EC to ppm is as follows: ppm500 = EC x 500; ppm700 = EC x 700; Some examples of how this works, using a conductivity reading of 2.4EC: ppm500 scale: 2.4EC x 500 = 1200ppm [500 scale] (or 1200ppm / 500 = 2.4EC) The only difference is an EC meter displays readings in millimhos (mmhos) and a TDS meter displays the readings in parts per million (ppm). The TDS meter uses a conversion factor to display EC as an average ppm, usually at about a 700:1 ratio.

Typically, a ppm meter will take an EC reading of a solution in μS/cm2 (microsiemens) and then convert and display a reading in ppm. The most confusing part about using a parts per million meter is the fact that manufacturers of the meters use 3 different conversion factors from EC to achieve a ppm readout, depending on which country you live in - 0.50, 0.64 and 0.70. 2020-06-12 2020-12-08 ppm TDS. Siemens (S) Other electrical conductivity units are Mho cm, CF (in America and Australia) en EC. 1) The term EC is used as a general term for E lectrical C onductivity, on some conductivity meters, the actual conductivity is presented in "EC" units, 2020-11-25 ppm700 = EC x 700. Some examples of how this works, using a conductivity reading of 2.4EC: ppm500 scale: 2.4EC x 500 = 1200ppm [500 scale] (or 1200ppm / 500 = 2.4EC) ppm700 scale: 2.4EC x 700 = 1680ppm [700 scale] (or 1680ppm / 700 = 2.4EC) There are three conversion factors which various manufacturers use for displaying ppm's USA 1 ms/cm (EC 1.0 or CF 10) = 500 ppm European 1 ms/cm (EC 1.0 or CF 10) = 640 ppm Australian 1 ms/cm (EC 1.0 or CF 10) = 700 ppm For example, Hanna, Milwaukee 1 ms/cm (EC 1.0 or CF 10) = 500 ppm Eutech 1 ms/cm (EC 1.0 or CF 10) = 640 ppm 2019-01-14 EC X 700 = PPM 700; Example: 1.00 EC = 700 ppm.
