United Scientific Supplies UNSM41 4 in 1 Soil Meter

Features:

• This 4-in-1 soil moisture meter is designed to monitor import conditions that affect the health of plants. Test for sunlight, moisture, pH, and temperature levels all in one convenient hand-held device. The 8" long probe reaches root-deep into t soil. Overall dimensions of the meter are 13" long by 1.4" wide. Requires a 9V battery (not included).

• Measures soil pH value, moisture, temperature and sunlight intensity
