About this item 3-in-1 Soil Monitoring Gage: Instantly check soil moisture, light intensity,and PH levels with a single tool. All you need to do is insert the double probes into the soil, select the diagnosis you wish by sliding the switch, and then reading the info on the dial.There is a light monitor on the top of the device that reads the amount of light your plant is getting. Based on Color Zones:The moisture meter features a color-coded scale for easy reading. Red Zone (1-3), it indicates that the soil is very dry. For plants that should not be too short of water, only add water when the pointer is in the first half of the red zone.In the Green Zone (3-8), it means the soil is moderately moist. For plants that regularly require water, add water once the pointer reaches the second half of the green zone.Zone (8-10), it means the soil is already moist enough. PH Meter Soil is No Batteries Needed: The PH Soil Tester doesn't require batteries and easy to use. It measures soil moisture level, light as well as soil PH with just a flick of the switch,just insert it in the soil, read the dial, and remove. It shouldn't remain in the plant and should be cleaned after use. Insert the Probes into the Liquid: Carefully insert the probes into the liquid sample. Ensure the insertion depth is between 3cm and 15cm. For optimal accuracy, insert the probes to a depth of approximately 15cm (about 3/4 of the probe length) if the liquid is deep enough. 3 in 1 Soil Tester is Prevent Overwatering: Accurate moisture readings let you know exactly when to water,make sure you don't over water your plants. Double-needle Detection Technology strongly enhances the speed and accuracy of detecting and analyzing soil moisture and pH acidity.
