¿É¼ÇÁ¤º¸[(193)Orange]High Accuracy Plant Water Tester for Soil pH, Moister, Light, Temperature, 4-in-1 Soil Moisture Meter for Garden,Potted Plants
Noted : Inside need use 9V battery then can working , our standard packing without the batteries , so need you buy the batteries from yourside .If have any questions pls feel free contact with me .
Easy to operate and portable to carry around. Large LCD screen with green backlight. The temperature unit is ¡ÆC/¢µ switchable. Powered by a 9V battery(not included), and low battery indication. The soil tester will auto power off after 5 minutes of no operating. Made of good quality materials, rust-proof and durable. Material: Plastic+aluminium alloy Accuracy: 1¡ÆC/1¢µ Working Temperature: 5¡É~40¡É Soil Temperature Measurement Range: -9~+50¡É (16~122¢µ) Soil PH Measurement Range: 3.5-9.0 Power Supply: 1 * 9V battery (Not included) Probe Length: 19.7cm / 7.76in Item Size: 31.8 * 6.2 * 3.6cm / 12.52 * 2.44 * 1.42in Item Weight: 81g / 2.86oz Package Weight: 182g / 6.42oz Package Size: 35 * 8 * 6cm / 13.78 * 3.15 * 2.36in 1 * Soil Tester 1 * User Manual (English)
Measuring range and reference data 1. Illumination measurement A. press the ON button to turn ON the instrument B. Aim at the highest point light source light sensor window. C. the current light intensity will be displayed on the LCD. Note: do not block light or create shadows for light sensors 2. PH range measurement A. Push the [PH/¡É] button on the back to the PH position. B. Insert the probe vertically into the soil and test as soon as possible. C. press the button [ON] to start measuring. D. The PH value of the test will be displayed on the LCD E. Measure several times to get the exact value required. Note: 1. Insert the probe vertically, at the edge of the middle stem. 2. Please gently push into the soil to avoid damaging the probe. 3. If the measured soil is too dry or fertile to give an accurate PH, the user can sprinkle water and measure it again half an hour later 3. Moisture measurement A push the [PH/¡É] button on the back to the ¡É position B insert into the soil as vertically as possible. C press NO key to start measuring D soil moisture values will be displayed on the LCD screen. E is measured several times to get the exact value needed. 4. Temperature measurement; A when measuring humidity, the value of soil temperature will be displayed on the LCD screen at the same time. B. Press the button of [¡É/¢µ OFF] to set the humidity display to be ¡É or ¢µ. Note: if the user does not insert the probe into the soil, the correct ambient temperature of the external space is displayed. Soil ph Soil ph is also called "soil reaction". It's an acid-base reaction of a soil solution. Mainly depends on the concentration of hydrogen ions in the soil solution, expressed in terms of pH. A solution with a pH of 7 is neutral; Acidic reaction occurs when the pH value is less than 7. A pH greater than 7 is a basic reaction. Soil acidity can be generally divided into the following grades: PH value soil pH < 4.5 extremely acidic 4.5 5.5 strongly acidic 5.5 6.5 acid 6.5 7.5 neutral 7.5 8.5 alkalinity 8.5 9.5 strong alkaline > 9.5 is extremely alkaline
