This instrument is a great aid for horticulture. It can measure the pH value of soil, soil moisture, and light intensity. No battery required.

Usage Instructions:

When measuring the soil pH and humidity, first insert the probe deeply into the soil, leaving about 1 centimeter above the probe.

Press the button on the pen to MOIST. MOIST is the moisture level key; in the chart, it corresponds to MOIST. DRY means dry, WET means wet. Values 1–3 (red area) indicate that watering is needed, 4–7 (green area) indicates it is appropriate. Adjust the watering time according to the plant species. Values 8–10 (blue area) indicate that it is too wet.

Press the button on the pen to PH; PH refers to pH value, which is listed as 8-3.5 in the table. ALKALINE indicates alkali, ACDIC indicates acid, and a value of 7 generally represents neutrality. The lower the value, the higher the acidity. Please adjust the soil pH according to the plant species. 

The LIGHT key indicates light intensity, with a measurement range of 0-2000 lumens. The higher the value, the stronger the lighting; please decide whether shading is needed based on the plant variety.

When using it, be careful not to touch the stones while inserting the electrode. Do not apply excessive force, otherwise the electrode may be damaged. Clean the electrode thoroughly after use.

Precautions:

1. When using it, be careful not to touch the stones while inserting the electrode; do not apply excessive force, otherwise the electrode may be damaged.

After use, the electrodes must be cleaned thoroughly. (Direct insertion into water for measurement is strictly prohibited.)

2. It should not be inserted into the soil for long-term use! Otherwise, it may be damaged.
