- Great value for money
Conductivity Standard by Growth Technology has an electrical conductivity (EC) of 2.76 ms/cm ensuring that your EC/CF meter is calibrated and that it gives the correct reading when mixing nutrient solutions as too high, or too low, could have a detrimental effect on how plants grow and flower.
This standard is 2.76mS/cm and meters that are calibrated in milliSiemens should be calibrated to this level. For meters that read in parts per million (ppm) things are a little more complicated. All EC meters measure EC in mS/cm. The meters that have a read-out in ppm have electronically converted mS to ppm. The problem is that different manufacturers convert mS to ppm in different ways.
- 1 mS = 500 ppm meters : 2.76 mS = 1380 ppm
- 1 mS = 666 ppm : 2.76 mS = 1838 ppm
- 1 mS = 700 ppm : 2.76 mS = 1932 ppm
This should be a regular procedure to ensure the best results from the meter.
Pour as much EC standard as is necessary to cover the electrodes. Discard the standard safely after calibration. Do not return it to the bottle it came from.
When using Conductivity Standard for EC meter should read 2.76, if not, it will need to be calibrated. If you’re unsure on how to carry this out, check the meter’s instructions.
Conversions: 1 Teaspoon = 5mL | 1 Tablespoon = 15 mL | 1 Ounce = 30mL | 1 Cup = 240 mL
Conductivity is a measure of water’s capability to pass electrical flow. This ability is directly related to the concentration of ions in the water. These conductive ions come from dissolved salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds. Compounds that dissolve into ions are also known as electrolytes. The more ions that are present, the higher the conductivity of water. Likewise, the fewer ions that are in the water, the less conductive it is. Distilled or deionized water can act as an insulator due to its very low (if not negligible) conductivity value. Seawater, on the other hand, has a very high conductivity.
Ions conduct electricity due to their positive and negative charges. When electrolytes dissolve in water, they split into positively charged (cation) and negatively charged (anion) particles. As the dissolved substances split in water, the concentrations of each positive and negative charge remain equal. This means that even though the conductivity of water increases with added ions, it remains electrically neutral.
Conductivity is usually measured in micro- or millisiemens per centimetre (uS/cm or mS/cm). It can also be reported in micromhos or millimhos/centimetre (umhos/cm or mmhos/cm), though these units are less common. One siemen is equal to one mho. Microsiemens per centimetre is the standard unit for freshwater measurements. Reports on seawater conductivity use micro-, milli- and and sometimes even just siemen/mho per centimetre, depending on the publication.
“Despite this product at first sight looking rather daunting, I found the conductivity standard rather easy to use. It is a must-have product in my opnion.”
“What an easy process from start to finish! Ordered my bits and bobs online and they arrived a couple of days later with no issues. Me and my wife have had a great time designing and building our indoor garden. We are looking forward to watching our crops grow.”
“The overall service and communication is second to none. My plants are superb now with excellent root growth and we are over the moon with the selection we made from your website. The Staff and owners are lovely people, so helpful and pleasant and a pleasure to deal with. Congratulations on developing such an excellent company and many thanks. Every plant is showing already, so we shall now sit back and enjoy watching our beautiful indoor garden grow.“
