Instructions:

Step 1: Switch moisture/pH/light position
Step 2: Stick the probe into the soil about 2-4 inches
Step 3: Adjust the position of the probe until the pointer on the dial swing slightly
Step 4: After 10 minutes, Note moisture/pH/light level in the dial
Step 5: Remove probe from soil and wipe clean after each use

Before Using:

1. If the soil is too hard and dry, easy to damage the probes.Do not touch the stone or hard rock soil. Copper and Aluminum itself does not belong to the hard material, so if the soil is too dry and hard to insert, you can use auxiliary agricultural tools drill hole and then insert.

2. Design for testing soil ONLY. No test for water

Do not be used to test pure water or other liquid, electrolytic response index will be affected, can only be used to measure the soil.
3. Clean and wipe the probes after each using.
