precautions

1. When using, be careful not to touch the stone when inserting the electrode. Do not use too much force, otherwise it will easily hurt the electrode. Wash the electrode in time after using it.(It is forbidden to directly extend into the water for measurement).

2. Can not be used in the soil for a long time! To avoid damage.

3. The products are made in China, mainly foreign trade. No Chinese instructions, do not order if you mind!

Usage:

when measuring the pH value and humidity of the soil, first insert the probe into the soil as deep as possible, leaving about 1cm on the probe.

Move the button on the pen to MOIST. MOIST is the moisture key, which corresponds to MOIST, DRY and WET on the table. The value 1-3 (red part) indicates that watering is required, 4-7 (green part) is suitable. Please adjust the watering time according to the variety of plants. 8-10 (Blue part) says that Alaska pollock is wet.

Touch the button on the pen to PH, PH is the PH key, corresponding to the 8-3.5 value on the table, ALKALINE is alkali, ACDIC is acid, value 7 is basically neutral, the smaller the number, the greater the acidity. Please adjust the soil pH according to the plant variety.

The LIGHT key is the illuminance. The measurement range is 0-2000 lumens. The larger the value, the stronger the illumination. Please decide whether to shade according to the plant variety.

soil pH

soil pH has a great influence on soil fertility and plant growth. Many soils in Northwest and northern China have large pH values, while red soil in southern China has small pH values. Therefore, crops and plants suitable for soil pH can be planted. For example, acidophilous tea trees can be planted in red soil region, while alfalfa has strong alkali resistance. Soil pH also has a great influence on the availability of nutrients, such as the availability of phosphorus in neutral soil; The availability of trace elements (manganese, copper, zinc, etc.) in alkaline soil is poor. In agricultural production, we should pay attention to the pH value of soil and take active measures to adjust it.
