Florasol pH4 calibration solution is for pH-meters. A monthly calibration of your equipment is essential to obtain precise results.

Green Gold Electrode Cleaning Solution works to clean both, pH & conductivity meters. Removes both organic & inorganic deposits from meter sensors. Use monthly or as needed to refresh your meter & keep it working. Compatible with most testers.

Citric Down will lower the pH level of your nutrient solution. The ideal pH for most hydroponic nutrient solutions is between 5.8 & 6.2, with some exceptions. Nutrient lockout will occur if pH levels are outside the optimal range.

Cyco pH Up raises the total pH value of the made nutrient solution. Recommended pH for most plants is 5.5 to 6.5.

HI70032P is a premium quality 1,382 mg/L (ppm) TDS calibration solution standardized with a conductivity meter that has been calibrated with potassium chloride NIST 2202 SRM in deionized water for analytical use in accordance with ISO 3696/BS3978.

Green Gold Solutions help keep your meters in good working order. Always make sure your electrode is kept in an electrode storage solution. If dry, refill the pH meter cap. Solutions are compatible with most testers.
