This liquid testing kit has a pH range of 4.5 - 9.0.Just half-fill the test tube with the solution you want to test, add 1 drop of this testing liquid and shake well. Wait for 30 seconds then compare the colour of the test tube solution with the colour chart on the side of the bottle.Very accurate, ...

It is recommended that pH instruments are cleaned and calibrated at least monthly to provide you with the most accurate reading. The pH measuring equipment is calibrated to pH 7.0 first (buffer) then to pH 4.0 (slope). The pH buffers are essential for use with all pH products for the calibration of ...

A digital hydroponic testing meter for measuring water’s acidity, alkalinity, electrical conductivity (EC), total dissolved solids (TDS), temperature, and salinity (salt content) to help optimize its quality for gardening and water treatment applications. The highly responsive sensor probe utilize...

Use a pH tester to gauge whether your water requires an adjustment.This pH Up Solution will allow you to decrease your pH level gradually because you mix 10ml per litre of water to increase your pH level by 1 (ie. from pH 5 up to pH 6). You do not want to increase the pH so much that you need pH dow...

It is recommended that your EC instruments are cleaned and calibrated at least monthly to provide you with the most accurate reading. The EC 2.77 solution is used to check that you have cleaned the EC/CF probe.To ensure solutions remain accurate: - Avoid cross-contamination- Decanter into a smaller ...

pH Up & pH Down are tank controllers that assist in reaching the desired pH level. The pH scale measures how acidic or basic (alkaline) a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic (alkaline).Plants thrive in a pH range of...
