Short lengthHigh-precision dual-purpose soil detector

MoistWater and humidity monitoring

pH value measurement

Technical specifications of the high-precision dual-purpose soil detector:

 PH range: 3-8 PH; moisture range: 1-80%

 PH accuracy: ±0.2PH; moisture accuracy: ±1%

 Environmental temperature: 5-50℃

 Measurable depth: Short version, 6 cm                      

When using it for the first time, wipe off the protective oil layer on the probe section with a cloth. When measuring the soil pH and humidity, insert the probe deeply into the soil in a clockwise direction. Wait for about 10 minutes before reading the pH value, then press the silver button next to it to switch to the humidity measurement mode.

Note during use: Do not touch the stones when inserting the electrodes, and avoid using excessive force, as this may damage the electrodes; do not place the instrument near magnetic materials, and do not leave it in soil for more than 1 hour. After use, clean the electrodes thoroughly for next time.

    Soil pH, also known as "soil reaction," refers to the acid-base reaction of soil solutions. It primarily depends on the concentration of hydrogen ions in the soil solution, measured by the pH value. A solution with a pH value of 7 is neutral; a pH value less than 7 indicates an acidic reaction; a pH value greater than 7 indicates an alkaline reaction. Soil pH can generally be divided into the following levels:

 pH value – Soil acidity and alkalinity

<t_4.5 Extremely strong acidity 4.5—5.5 Strong acidity 5.5—6.5 Acidic 6.5—7.5 Neutral>
7.5—8.5 Alkaline 8.5—9.5 Strong Alkaline ＞9.5 Very Strong Alkaline
