 These solutions are used to calibrate pH meters to assure they are accurate and working properly. You should check your pH meter frequently because the properties of the meters membrane is constantly changing from normal use and aging. We recommend a two point calibration between 4.0 and 7.0 to assure that your meter is accurate across the scale. This is why the Genesis solution is available in twin packs of 4.0 and 7.0.

 Use to store your pH meter electrode between use. This solution is designed to keep your electrode sensing membrane and reference junction clean and unclogged and ready for use. Store you electrode directly in a small cup of solution or saturate a sponge in the cap of your meter for storage between use. This will prevent your permeable glass membrane from becoming dry and from mineral deposits clogging the surface. This solution is designed to equalize the osmotic pressure of the reference solution in your meter junction to keep the reference solution from seeping out and prematurely aging your meter. Should your electrode membrane dry out soak it in this solution for at least two hours before use. NEVER STORE AN ELECTRODE IN DISTILLED OR DEIONIZED WATER. | | Item # | Description | Price | Add to Cart |

 Technafloras pH Up and pH Down enable the gardener to moderate and maintain optimum pH levels. The pH scale is a measure that describes the relative acidity or alkalinity of a solution or medium. Both pH-balancing aids are manufactured using the highest-quality ingredients: potassium hydroxide to raise pH, and nitric acid to lower pH. While ensuring stringent industry safety standards are met, Technafloras pH Up and pH Down are potent and effective in small doses. | | Item # | Description | Price | Add to Cart |
