Control Wizard Products is now introducing its Accurate pH & moisture meter for soil growers. Until now, soil growers with the need to keep careful tabs on the pH of their soil has had to rely on either cheap, poor quality meters that are very expense and hard to get. This new meter is the best of both worlds. It is relatively inexpensive and is manufactured to high quality standards. No batteries are required. 1 year limited warranty.

New name! New label! Same easy to use meter! Now with the 4 most popular scales: EC, CF, 500:1ppm, and 700:1ppm! The E.C. Dipstick dissolved salts pen operates on 3 common inexpensive AA alkaline batteries. Measures in PPM, EC and CF scales.

There is no calibration required. It calibrates itself each time you replace the batteries. It is water resistant so a light emersion in the plant nutrient should not hurt. However, it is a good idea to test small amounts of nutrient away from large bodies of water just in case you have butter fingers.

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.

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.
