This instrument is a good helper for gardening. It can test the pH value (pH), soil moisture and illuminance of the soil. No battery required.
1. Body size: 50*38*290mm
2. Probe length: 205mm (can not be directly placed in the water to measure water, it will damage the electrode!)
3. Weight: about 100 grams
When measuring the pH value and humidity of the soil, first insert the probe into the soil as far as possible (15CM or more) (please note: it cannot be directly inserted into the water test)
? Soil moisture measurement:
Move the button on the pen to MOIST, MOIST is the moisture button, the corresponding table is MOIST, DRY is dry, WET is wet, the value 1-3 (red part) indicates that watering is required, 4-7 (green part) It is suitable, please adjust the watering time according to the variety of plants, 8-10 (blue part) is too wet.

Push the button on the pen to PH, PH is the pH key, the corresponding table is 8-3.5 value, ALKALINE is alkali, ACDIC is acid, the value 7 is basically neutral, the smaller the number, the higher the acidity, please according to the plant Variety to adjust soil pH
? Illuminance measurement:
The LIGHT button is the illuminance. The measurement range is 0-2000 lumens. The larger the value, the stronger the illumination. Please decide whether you need shading according to the variety of the plant.
The probe should be inserted into the soil 2/3 (about 15CM or so) depth! ! , the measurement is accurate!
