  Working Principles
Click to ViewMoisture Meter Function: Slide the switch to the MOIST setting Insert the probe ¾ of its length into soil The moisture reading registers on a scale of 0 (dry) – 10 (moist) and is located in the middle row of the reading output area. If your reading registers in the first half of the RED zone (0-1.5), it’s time to water For moisture loving plants, if the reading registers in the second half of the GREEN zone (5-7), it is then time to water Your plants do not need additional water if your reading registers in the BLUE zone (8-10) Light Meter Function: Slide the switch to the LIGHT setting Place the photo sensor near the plant with sensor oriented towards the light source sensor is located on the front centre of the meter. Take the reading from the top, white area of the reading output area. Readings between 0-500 indicate low light levels, while readings of 700-2000 indicate strong light level. pH Meter Function: Slide the switch to the pH setting Collect soil below 2” of the surface. Remove stones and other debris from the sample. Mix the soil with water until it turns to mud. Gently wipe the tester probe with soft, dry cloth. Insert the meter 4-5” into the sample and make sure the probe is in contact with sample for one minute; then note the reading. In order to achieve the adequate pH level, you can raise it with lime or lower it with peat moss. For best results you should use a pH Up or Down solution available from your retailer

  User Instructions
With Three-Way Soil Meter For Moisture, Light Intensity and pH Testing Meter, you can easily check on the condition of your plants. The moisture meter will quickly tell whether your plants are doing well. Firstly, let you know that dry and needs water or wet and could use a day to dry out, you will never over/under water your plants again. Secondly, it helps you to control pH level in soil, acidic or alkaline is suitable for your plants. Thirdly, testing whether plants getting adequate sunlight. Above all, equipped with this meter, you can give the best care to your plants and keep the soil and lawn healthy and happy. Note: Please remove probes from soil and wipe clean after each use. Soil pH is one of the most important factors that can be overlooked in the garden. pH has impacts on the availability of nutrients and of the plant’s ability to take them up. If the pH of your garden soil is not in the optimal range for the plants you are trying to grow you may end up having issues. Often plants grown in a soil that does not have the optimal pH don’t produce or if they do their harvests are low while the plant may look stressed. On today’s joint episode between the Testing Garden Assumptions and Urban Garden Series, I am going to take a look at soil pH, how to easily measure it and how you can adjust the pH over time if need be. pH is measured on a 14 point scale with 0 being the most acidic 7 neutral and 14 the most basic. Three Way Soil Meter With PH Detector is a Perfect tool to test the soil conditions (Moisture/Light/ PH) of fruits, flowers, vegetables, shrubs, etc. Its an Ideal and necessary tool for gardeners, vegetable and fruit growers, and all those who plant trees and grass. The meter can be Simply inserted into the soil and switch to the setting you want to measure and read the scale. A 3-in-1 soil tester is a metal pronged instrument that is inserted into the soil to test soil pH, light intensity, and moisture levels. A soil tester takes some of the guesswork out of where and how to plant your flowers, shrubs or trees. You can use the tester to determine the current levels of the soil, and alter them according to the specific needs of the plants you wish to place there. Plant grasses, shrubs, flowers or trees that need similar conditions together in one area, with those needing different conditions in a separate area of the yard or garden. Clean the prongs of the tester with distilled water and a clean cloth before use, and between uses. This will keep the readings from being affected by the pH of a previous test or tap water. Insert the prongs into the soil you wish to measure. The first reading that appears will be a pH, which is measured on a scale from 1 to 14, with 1 being the most acidic and 14 being the most alkaline. Seven is a neutral pH. Most plants will grow in a pH between 6 and 7.5. The soil tester measures pH levels from 3.5 to 8. Alter soil pH by adding limestone to raise it, or sulfur to lower it. Press the button on the tester to view the moisture readings. The tester measures the percentage of moisture content in 10 percent increments, from no moisture to complete saturation. Most plants will want moist soil in the mid-range. Sand can be added to soil to increase drainage capabilities for excessively wet soil. Press the button on the tester again to view the light readings. Light readings measure light intensity in foot-candles from 0 to 2,000. For reference, average indoor home lighting is around 100 foot-candles. Plants requiring full sun can be planted in the upper light ranges, and plants requiring shade can be planted in the lower light areas. Things You Will Need Soil tester Distilled water Clean cloth
