The ppm 700 scale is based on measuring the KCl
Potassium Chloride
This medication is a mineral supplement used to treat or prevent low amounts of potassium in the blood.
What PPM scale do I use for general hydroponics?
As plants consume nutrients and water, the nutrient strength in the hydroponic reservoir will change. GENERALLY, nutrient strength should run between 800 to 1500 parts per million (ppm).
What's the difference between PPM and EC?
EC is the only true measurement and does not have to be converted so EC is always the same. If you use PPM/TDS, which is most popular in the US, you need to make sure your meter is set to the same scale your nutrient is using, since there are 2 different conversion formulas.
Is PPM the same as TDS?
Total dissolved solids (TDS) is measured as a volume of water with the unit milligrams per liter (mg/L), otherwise known as parts per million (ppm). According to the EPA secondary drinking water regulations, 500 ppm is the recommended maximum amount of TDS for your drinking water.
How do you read a PPM meter?

What does PPM 700 scale mean?
The ppm 700 scale is based on measuring the KCl or potassium chloride content of a solution. The ppm 500 is based on measuring the NaCl or sodium chloride content of a solution. The ppm 500 scale is also referred to as TDS - total dissolved solids.
What happens if PPM is too high?
If there is no change in PPM/EC between your nutrients and runoff, this means your plants aren't taking up nutrients properly. This is usually caused by spikes or drops in pH. If the PPM/EC reading is higher in your runoff than in your nutrient solution, you'll likely be dealing with salt buildup around the roots.
Which TDS is best for drinking water?
between 50-150What is the best TDS level for drinking water? Ans: Generally, the TDS level between 50-150 is considered as the most suitable and acceptable. Ans: If the TDS level is about 1000 PPM, it is unsafe and unfit for human consumption.
How do you convert ppm to TDS?
To obtain an approximate sodium chloride TDS value, multiply the EC reading (in milliSiemens/cm) by 1000 and divide by 2. To get an EC value, multiply the ppm reading by 2 and divide by 1000.
Is high TDS water harmful?
High levels of TDS means it is unfit for consumption and several diseases like nausea, lung irritation, rashes, vomiting, dizziness etc., Drinking water with elevated amount of TDS for longer periods will expose body to various chemicals, toxins and may cause chronic health conditions like cancer, liver, kidney ...
What are PPM levels?
This is an abbreviation for "parts per million" and it also can be expressed as milligrams per liter (mg/L). This measurement is the mass of a chemical or contaminate per unit volume of water. Seeing ppm or mg/L on a lab report means the same thing.
What is PPM for flowering?
Early Flowering: 900 to 950 PPM — As your plants grow, they need to eat more. PPM readings will reflect the particles in the increased nutrients. Mid-Stage Flowering: 950 to 1100 PPM — Your plants' nutrient intake continues to increase at this stage.
How do you adjust PPM?

How do you convert ppm to EC?
To get an EC value, multiply the ppm reading by 2 and divide by 1000. Thus, if your EC is 1: 1 * 1000/2= 500 ppm.
What is EC meter used for?
An EC meter measures the potential for an electrical current to be transported through water. This is known as molar conductivity (electrolytic conductivity) and is measured in siemens (S).
What is a ppm meter used for?
A peak programme meter (PPM) is an instrument used in professional audio that indicates the level of an audio signal.
How many ppm in water is safe?
What is the best TDS level for drinking water? Ans: Generally, the TDS level between 50-150 is considered as the most suitable and acceptable. Ans: If the TDS level is about 1000 PPM, it is unsafe and unfit for human consumption.
What is the difference between a PPM 700 and a PPM 500?
What's the difference? The ppm 700 scale is based on measuring the KCl or potassium chloride content of a solution. The ppm 500 is based on measuring the NaCl or sodium chloride content of a solution and is also referred to as TDS - total dissolved solids. Individual nutrient ions have different electrical effects! The true ppm of a solution can only be determined by a chemical analysis. ppm cannot be accurately measured by a CF or EC meter. They are present on Bluelab products as a conversion guide only. The conversion is as follows;
What is a PPM reading?
the ppm reading is a conversion of EC. 500 to 700 EC eh? EC is the only true reading, all others are based off EC using different conversion factors from brand to brand,
Is 700 scale law?
Using the 700 scale is not a law, you could convert all their numbers to 500 scale easily enough. But learning the EC route is a smarter path in the long run, regardless.
What is the difference between PPM 500 and PPM 700?

Where are PPM meters made?
I’ll list a few of the more popular companies. However, there are tons of elcheepo TDS/PPM meters made in China and it’s anybody’s guess which scale they are using.
Do you need to know the scale of a PPM meter?
Now that we know the scale our PPM meter is, we need to know what scale the nutrient manufacturers are using. If they are using the same scale as our meter, we’re golden. If not, we need to know so we can adjust the concentration of the solution accordingly. The following is a brief list of common nutrient companies and the PPM scale they use when referencing dosage.
