Sale green round head three-in-one soil tester soil moisture meter to measure ph light

Soil moisture meter/soil pH meter/light intensity meter (three functions)

This is a product for export. It does not require a power supply and integrates three functions. It can measure the humidity of soil \PH \the intensity of sunlight required for plant photosynthesis. Easy to use, good-quality.

This instrument is a good helper for gardening. It can test the PH value (pH) of soil, soil moisture and light intensity without battery.

Material: plastic

Single belt packing weight: 90g size: 33*10.5*4.5CM

Probe length: 20.5cm

Box gauge 54*40*36cm/100pcs 9.9kg

Please note that please soak the soil with water before inserting the soil. The probe should be inserted into the soil at a depth of 2/3 (above 10CM) before measuring. (The probe cannot be directly put into the water to measure water, which will damage the electrode!)

Method of use:

When measuring the pH value and humidity of the soil, insert the probe into the soil as deeply as possible.(10CM already on)

Toggle the key on the pen to MOIST,MOIST is the moisture key, the corresponding table is MOIST, DRY is dry, WET is wet, and the value is 1-3 (red part

Points) indicate that watering is required, 4-7 (green part) is appropriate, please adjust the watering time according to the variety of plants, 8-10 (blue part) indicates that it is too wet

It's up.

Move the key 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 is 7 basic

It is neutral. The smaller the number, the greater the acidity. Please adjust the soil pH according to the variety of plants.

LIGHT key is the illuminance, measuring range 0-2000 lumens, the larger the value, the stronger the illumination, please decide whether to cover according to the variety of plants

Yin.

When using the plug-in, pay attention not to touch the stone, do not use too much force, otherwise it is easy to damage the electrode. Wash the electrode after use.

soil pH

Soil pH is also called "soil reaction". It is the acid-base reaction of the soil solution. mainly depends on the concentration of hydrogen-ions in the soil solution

Expressed in terms of pH. A solution with a pH value equal to 7 is a neutral solution; a pH value less than 7 is an acidic reaction; a pH value greater than 7 is an alkaline reaction

Should.

Soil pH can generally be divided into the following levels:

pH value of soil pH

<4.5 very acidic

4.5-5.5 strong acid

5.5-6.5 acidic

6.5-7.5 Neutral

7.5-8.5 alkaline

8.5-9.5 strong alkaline

> 9.5 extremely alkaline

adjustment of soil ph:  
1. Improvement of acid soil lime is often used to achieve the purpose of neutralizing active acid, latent acid and improving soil structure. Purple shale powder, fly ashes, plant ashes, etc. can also be used.

2. Artificial acidification of neutral and calcareous soils sulfur powder (50g/m2) or ferrous sulfate (150g/m2) can be used for open flowers, which can reduce 0.5-1 pH unit. Also available alum fertilizer water. 
3. Alkaline soil application of gypsum, but also available phosphogypsum, ferrous sulfate, sulfur powder, acid weathered-coal.
