Product Install
Prepare water storage tank solution on site
1. Take soil at the measurement site, add water and stir, the ratio of water and soil is 5: 1
2. Connect the electrode to the water storage tank.
3. After the water and soil boundaries are stable, put the water storage tank into the upper aqueous solution, fill the solution, and remove it for use
Digging to store electrodes
1. Dig a pit with a diameter of about 10 cm and a depth of about 20-50 cm, and put the PH electrode containing the solution into the pit.
2.
Backfill the soil while leaving a low-lying place to seep under water, if there is no rain for two months, you need to add water manually

Rain keep
Leave a low-lying place above to ensure that it will remain in the rain.
Artificial watering
If there is no rain for more than two months, you need to manually water
