The path for Perfection in your pH Solutions and Measurements

Frequent calibration is the best way to maintain the pH because it keeps your readings accurate and reliable. All electrodes are based off of slope and offset according to the Nernst equation, and many of them will change as they age.
When electrodes are out of the equation or losing its accuracy, calibration comes in.

Using Complete Hydroponics pH Standard Buffered Solutions for calibration informs you of any damage in the electrode. For example: Offset is the electrode's millivolt (mV) reading in pH 7 buffer, and the slope is the mV change per pH unit. If these numbers are off during calibration, that's a strong indication that the probe is damaged, dirty, or too old and needs to be replaced.

Perfect Accuracy:
Our standard pH calibration solutions have an accuracy of +/- 0.01 pH at 25°C (77°F) and come in 3 different pH values 4.01, 7.0, and 10.01. Our products are very popular and are dyed in different colors so they can be easily identified when you are busy working on your system.
Like all of our calibration buffers, the standard solutions are made in accordance with ISO standards, are NIST traceable, and come in one standard size 500mL. (Note that while all standard solutions are certified, not all of them come with a certificate. Some certificates may be available upon request.)

Works in every meter:
Complete Hydroponics pH Standard Buffered Solutions for calibration are great for use in virtually any application and with most meters. Whether you are measuring the pH of food with a fancy wireless pH meter or using a benchtop meter in a laboratory setting, standard pH buffers will likely work for you.

Excellent for Bracketing:
What is bracketing? Also known as a two-point or multi-point calibration, bracketing consists of calibrating to two pH points; one above and one below your desired pH range. For example, if you want to measure the pH of solution, which has a pH around 6.3, you could use our calibration solution pH 4.01 and pH 7.0 for a two-point calibration.

Advice! For better accuracy, we recommend performing a calibration at pH 7.0, since this is how the offset is determined. Calibrating at pH 7.0 helps you determine problems, such as a contaminated  or broken probe, and helps avoid any errors in measurement.

Maintaining your pH Calibration Solutions
Our pH buffers come in FDA approved light filtering bottles to help maintain their pH values. Complete Hydroponics calibration solutions come in light white transparent bottles so you can see the colors of the respective measurement. However, it is very important to keep the Calibration solution out of the reach of light or heat radiations to maintain the integrity and assure accuracy.
In order to keep from contaminating your buffer, never submerge your electrode right into the bottle. Pour out just what is needed into a container rinsed with deionized (DI) water, and use that for your calibration. Never pour used buffer back into the bottle!
Although we recommend calibrating every day, we understand that it is a time-consuming task and many people are busy. If high accuracy is not important in your measurements it's okay to calibrate once or twice a week.

 Complete Hydroponics Standard Buffered Calibration Solution for calibration is designed to have a long shelf life when left unopened. Once opened, a buffer with a pH lower than 7 will last around 6-10 months, while a buffer with a pH over 7 will be good for about 3-5 months.

pH Balance
If the pH levels are outside of the optimum range then the plants will lose the ability to absorb some of the essential elements required for steady growth. Above pH 6.5 many nutrients and micro nutrients precipitate out of solution and stick to the walls of the hydroponic reservoir.
This is one of the reason, and I believe one of the most crucial about why it is very important to keep a balance in your pH solutions.
Complete Hydroponics gives you the opportunity to fix these problems with two effective and powerful pH stabilizers such as:

             pH adjusters
These products guarantee a fast acting balance in your solutions so you can keep a perfect environment in your plant’s hydroponic system.
