the turbidity meter may read 15 NTU and the concentration of the standard solution to yield this response may be 5 mg/l. The conversion factor would be 1 mg/l = 3 NTU = 1 ppm based on 1 mg/l = 1 ppm. Each application may have...
Most organizations select resource planning software as a component of a larger PPM solution. So, pay close attention to the resource planning capabilities of the PPMsoftware you’re evaluating. Ascertain the overall solution’s ability to solve the problems you’re experiencing, as well as its ab...
So this is basically "parts per part," meaning that for one part solution you have 0.0002 parts salt. But of course, having this many decimal points isn't exactly convenient, so to convert to PPM you multiply by 1,000,000 = 106, giving: 0.0002 × 106= 220 PPM. The general approach ...
Total alkalinity should be between 80 and 120 parts per million (ppm). Calcium hardness should be between 150 and 250 ppm. If either of these levels is too high or too low, it can make your hot tub's water cloudy. After you've adjusted the pH levels, it's a good idea to do a ...
small amount of nutrients, you might want to invest the$25 or so to get a TDSmeter.Note: If you get a TDS meter, you are definitely going to need calibration solution to make sure the meter is giving you proper readings. I recommend1000ppm calibration solutionwhich will cost about $10....

Parts per million (ppm) is a unit typically used to express the concentration of a substance in a solution or mixture. However, ppm can also be used to…
•Aeroponic Hydroponic System.In an aeroponic system, the roots of the plants aren’t ever suspended in water. Instead, the nutrient solution is misted on the plants. Because the plants are suspended in air rather than water, the nutrient solution doesn’t have to be oxygenated, as the ...
