The digital pen style EC meter can measure both pH and EC. It is suitable for hydroponics, aquarium, pools, laboratories, and much more. What stands out most about this digital EC meter is the large LCD screen. Charts to convert ppm/EC/CF One of the problems with conversing with Growers in different areas and with different equipment is that CF/ ppm /EC meters will express different yet very similar measurements all effectively say the same exact thing it's just a case of what measurement you use Electrical Conductivity of the solution under test. So a PPM/TDS meter is a EC meter that converts the EC value into PPM values.

Here’s the catch to using this method: the TDS meters made by different companies use different formulas to convert EC to TDS. This means you can get different PPM measurements for the same EC value, depending on which brand of meter you use.

We are not going to get into what the ideal value of PPM or EC is, Just cover how to measure and quantify a fluid.
We will be using this for the Urine based aquaponics unit, we need to be able to control the strength of the growing fluid in the system but for the person
TDS PPM Meters ppm = parts per million; ppt = parts per thousand; 1 ppt = 1000 ppm 1 ppm = = 1 milligram per liter water; 0.0038 grams per gallon water 1413μS/cm, 1382 ppm (0.5 conv.), 1500 ppm (0.7 conv.)
The meter comes with the Field Scout Soil/Water EC probe. This single, stainless steel probe has a spe-cially designed conical tip. It can measure liquid EC (water or nutrient solutions) or in -situ soil salinity.

600 ppm as a rule of thumb. So, .333 EC = 200 ppm and .50 EC = 300 ppm, etc. The 0.00 - 20.00 EC scale just means your meter is capable of reading up to 20.00 EC - it's unlikely you would ever go much above 2.0 EC (1200 ppm).

Some dissolved salts with an EC of 2,200 microsiemens will have a ppm of 1,540 (I used a conversion factor of 0.7), but this does not mean the solution you measured has that 1,540 ppm. Use this portable EC meter and probe to measure soil salinity directly on golf greens, fairways, and athletic fields right on the spot, without conducting tedious soil sampling and soil preparation. You can test different levels in the soil profile with the eight-inch-long probe.
You simply remove the cap, and turn the meter on with the press of a button. It will usually take a couple of seconds to load up. When the EC meter has turned on, you will insert the end with the 2 prongs, into the nutrient solution, but do not fully submerge the whole EC pen. We are not going to get into what the ideal value of PPM or EC is, Just cover how to measure and quantify a fluid.
