Since TDS is not typically used in our industry, avoid conductivity meters that only read in TDS. Conversion from EC to TDS 1 mmhos/cm = 500-700 ppm 1 mmhos/  

Therefore, 2 EC is 1000 ppm on the 500 scale, and 1400 ppm on the 700 scale. Hydroponic Research - Feed it - Shirt Blue. Once relative humidity levels reach 

2.4EC x 700 = 1680ppm (700 scale) or 1680ppm / 700 = 2.4EC If you must grow using ppm (instead of EC), you will need to know the following; What PPM scale is the book (research material) referring to? Although water EC and PPM levels sound like a complex topic—and to a certain extent they are—a simple meter, using the best soil additives, and addressing your tap water with a filter if you wish, is all that you will need to do to provide healthy water to your cannabis grow. If you're new to hydroponics and have NO clue what all of the terminology means, this video is for you. Even if you're an intermediate grower and want to kno Basically, all TDS and PPM meters measure the EC, then they use equations to convert to TDS/PPM. Problem is there are t This is why I use EC rather than PPM. 2021-03-30 · I was dumb enough to stick with the PPM function on my meter for a long time because I could not find the EC function.

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. In other words, an EC of 1 is approximately 700 ppm.

That means 1.0 mS/cm x 500 = 500 ppm. There are many different scales in many industries. For example, three scales are usually used in hydroponics: the 500, 640, and 700 scales. The difference between them is in their use. The 700 scale is based on measuring the potassium chloride KCl concentration in a solution: 1.0 mS/cm x 700 makes 700 ppm

To convert from siemens to Ohms is s=1/ohms, you can also go the other way and do ohm=1/s for siemens to Hey guys, I am totally confused. I understand my TDS meter is testing the electrical conductivity of my water, but I just dont get how it all relates.
