How to measure EC? The easiest way is by using a digital meter, such as the Bluelab CF Truncheon. These work by measuring the electrical conductivity via the electrodes on the bottom of the meter. All you need to do is dip the end into your solution and check the digital reading.

What is the correct EC for hydroponics?
For most hydroponic crops, the ideal range of EC for most crops is between 1.5 and 2.5 dS/m. A higher EC could prevent the plant from absorbing nutrients due to increased (more negative) osmotic pressure, and EC levels that are too low could adversely impact yield.
How do you use EC probe?
An EC meter consists of two parts: a measuring cup and the meter itself. Perform an EC measurement
- For a correct measurement, it is important that the cup is clean.
- Add the liquid which you want to measure the EC to the measuring cup.
- Turn on the EC meter;
- Leave the meter in the measuring jug for a few minutes.
What is EC meter used for in hydroponics?
Measuring this tells you how much nutrient there is in the water. For most plants you want the EC measurement to be hitting between 1.2-1.6 during the vegetative stage and 1.6-2.4 during flowering, but this can be dependent on the type of plant that’s growing.
Is EC the same as TDS?
Total Dissolved Solids (TDS) and Electrical Conductivity (EC) are two separate parameters. TDS, in layman’s terms, is the combined total of solids dissolved in water. EC is the ability of something to conduct electricity (in this case, water’s ability to conduct electricity). That’s TDS!
What happens if EC is too high?
Excessively high EC levels lead to stunted growth, leaf damage and eventually plant death.
Is EC the same as pH?
Basics of using pH and EC meters pH refers to the acidity-basicity of a solution, which influences the solubility and availability of nutrients for plant uptake. Electrical conductivity (EC) is a measure of total soluble and dissolved salts in solution. EC is measured in units of electrical charge.
Is EC the same as ppm?
Summary. ppm stands for parts per million & is the most common domestically used unit when measuring TDS. EC stands for electrical conductivity, which is a measurement of the ability of something to conduct electricity. In horticulture, EC is the most accurate way to measure nutrient concentration in solution.
What should be the EC of drinking water?
Generally, the amount of dissolved solids in water determines the electrical conductivity. Electrical conductivity (EC) actually measures the ionic process of a solution that enables it to transmit current. According to WHO standards, EC value should not exceeded 400 μS/cm.
What does an EC meter read?
An EC meter measures the potential for an electrical current to be transported through water known as molar conductivity (electrolytic conductivity) and expressed as siemens (S).
How do you do a soil EC test?
How To Measure the Bulk EC
- Pick your testing location.
- Rinse the testing probe with deionized water, and make sure it is dry.
- Check the soil and ensure that the soil is moist.
- Use a ruler or auger to make a hole in the soil.
- Insert your probe directly into the soil, and take your measurement.
How do you test pH and EC soil?
Soil pH can be measured using a pH meter (usually mixing the soil sample with water or a salt solution) or by adding a dye to the soil and observing a color change that can be compared with a chart for pH determination. The latter method can be done using a kit that contains the necessary chemicals.
How do you adjust the EC of water?
You can easily lower EC by diluting your system with fresh water. Take measurements intermittently while adding water until it is mixed to the correction level. You can raise EC by adding fertilizer.
What does EC mean in gardening?
The easiest way to measure fertilizer level is to check Electrical Conductivity (EC). EC is the measure of total dissolved salts in a solution, the factor that influences a plant’s ability to absorb water. In horticultural applications, monitoring salinity helps manage the effects of soluble salts on plant growth.
