PH range measurement:
A. Push the (PH / ℃) button on the back to the position of PH.
B. Inserting the probe vertically into the soil, testing as soon as possible.
C. Press the (on) button to start the measurement.
D. The tested PH value will be displayed on the LCD.
E. Measure several times to get the exact value needed.
1. Insert the probe vertically, at the edge of the middle plant stem.
2. Push the soil gently to avoid damaging the probe.
3. If the measured soil is too dry or fertile, cannot measure the accurate PH value, the user can sprinkle some water and measure it again half an hour later.
A. Push the (PH / ℃) button on the back to the position of ℃
B. Insert into the soil as vertically as possible.
C. Press \\\"on\\\" key to start measurement
D. The soil moisture tested will be displayed on the LCD screen.
A. When the humidity is measured, the soil temperature value will be displayed on the LCD at the same time.
B. Press the (° C / °F off) button to set the humidity display to ° C or ° F.
Note: if the user does not insert the probe into the soil, the accurate ambient temperature of the external space will be displayed.
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-3mm measuring deviation due to manual measurement.
