4-in-1 Soil pH Meter – Garden Soil Tester

4-in-1 Soil Tester for More Accurate Plant Care

The RETOO E624 is a practical soil meter designed to check pH acidity, moisture, light, and temperature. Regular measurements help to better understand plant growth conditions, properly select fertilizers, and avoid nutrient deficiencies. The device is suitable for use at home, in greenhouses, gardens, vegetable patches, and outdoors.

Soil pH and Moisture Meter

The tester can measure soil pH from 3.5 to 9, making it suitable for various plant types. The approximate scale helps determine whether the soil is acidic, neutral, or alkaline: pH 3.5–6.5 indicates an acidic environment, pH 7 – neutral, and pH 7–8 – alkaline. The moisture scale from DRY+ to WET+ allows you to assess whether the soil is very dry, dry, normally moist, moist, or very wet.

Convenient Backlit Display

Results are easy to read on the backlit display even in low-light conditions. The device also measures soil temperature from -9 to 50 °C, and temperature units can be selected as needed – °C or °F. To perform a measurement, insert the probe into the soil approximately 5–10 cm deep and wait for the result to appear on the screen.
