The Bluelab Guardian Monitor Connect Inline is not only a constant indicator of the desired levels of pH, conductivity and temperature of your nutrient solution, it also data logs these critical parameters to your computer for you. It does not stop there. You can access the data via the cloud from a remote mobile device or computer to check for extreme variances to ensure these critical parameters are hitting the mark for crop success. For remote or cloud access, the computer you are already

Certified Organic Acidifier. pH Down is an additive designed to use where the pH needs to be lowered into a more acidic range. The organic acid present in pH Down gently lower the pH of water, making nutrients more available and increasing uptake. pH Down can also remove scale and hard water deposts, and is excellent as a greenhouse cooling pad cleaner. 1 gallon concentrate makes 70 to 2,560 gallons of solution depending on the original pH of water. Dimensions;. Length: 6.75. Height; 10.25.

Anura products are built to last and the EP70 is easy to use. Measures: pH, Conductivity, TDS, Salinity, and Temperature Water resistant case, IP67 rating. Able to replace the pH/Conductivity modules, this means you can save money with a replacement electrode probe instead of buying a brand new tester. Batteries included and over 100 hrs of battery life. Automatically turns off in 10 mins of non-activity, saving the battery. 50 memory data sets for recalling previous readings. Switches between
