The HortiCare nutrient tester is designed to test the levels of nutrient concentrations in solutions that feed plant roots. The unit will test the levels of other essential mineral elements in soluble form. This simple to use instrument is housed in a water resistant case, suitable for everyday use and features an easy to read 8mm LCD display. The unit measures EC (mS), cF or TDS (ppm) at the switch of a button. The HortiCare nutrient tester incorporates an automatic calibration feature. At the touch of a button, the instrument will automatically recalibrate itself when used in conjunction with 6.7 mS (67 cFor 4700 ppm) standard solution. The HortiCare tester is ideal for testing the amount of dissolved solids (nutrients) in water.

Low or high pH levels affect the availability of the minerals required by the plant. The correct pH range for hydroponics is between 5.5 and 6.5, for soil it is not so critical, but generally around 6.3; outside of these figures nutrient problems will quickly occur as minerals become insoluble. The nutrient strength needs to be matched to the current stage of plant development. Too high a concentration can quickly burn a plant, whilst too low produces pale, weak growth. Measuring is knowing. Good results are attainable by anyone prepared to stick to this rule. Whimsical guesswork rarely leads to success! The Nutriculture pH Test Kit allows quick and accurate monitoring of pH levels in your nutrient solution. For accurate acidity testing follow the procedure below. •Take a 2ml sample of solution from the tank in the test tube provided. •Add 2 drops of reagent. •Shake the test tube and compare the colour against the test strip to determine the acidity. •Discard the test solution and rinse out the test tube. •Adjust the pH of your nutrients and retest if neccessary.
