PH Sensor

pH levels are important in soils, irrigation water and spray tank solutions. Soil and water pH is the single most important aspect in determining nutrient availability to crops. pH levels in spray tanks determine the effectiveness of pesticides. This multi-purpose meter to help provide a healthy growing environment for all plants. It tests for soil alkalinity / acidity, soil moisture, and sunlight.

A pH Meter is a device used for potentiometrically measuring the pH, which is either the concentration or the activity of hydrogen ions, of an aqueous solution. It usually has a glass electrode plus a calomel reference electrode, or a combination electrode.^[1] pH meters are usually used to measure the pH of liquids, though special probes are sometimes used to measure the pH of semi-solid substances.  3in1 Moisture PH Light Meter for Hydroponic Plant Soil # Ideal tool for both indoor and garden plants care # Please clean the electrode after each use * 1 X 3 IN 1 PH LIGHT METER FOR PLANT SOILFEATURES.

With this 3 in 1 soil meter you can check in your garden, vegetable garden, lawn and potted plants whether the soil is suitable for a particular plant. Use the device to measure growing conditions for all kinds of plants indoors and outdoors. You can also check the humidity in the soil, the temperature and intensity of sunlight using this ground meter.

This 4 in 1 pH soil meter can be especially useful in lawn care in determining the soil conditions in different areas of your garden and finding the correct lawn seed and fertilizer. Bad spots in the lawn can be caused by poor drainage (wet soil, test the moisture), too much or too little acidity (test the pH), or the wrong light level (test light and use appropriate seed mix (sun/shade).
