Features: Test object: current light intensity, soil moisture, soil PH value, soil temperature. The four-in-one soil analyzer is mainly used to test soil ph, moisture and humidity, temperature and plant light intensity. It USES a 9V carbon battery with a simple operation and a probe length of 200mm. The instrument displays the parameters measured by liquid crystal display. The instrument also has the function of low power indication and automatic power cut off. It saves time and energy and is efficient. This instrument is suitable for planting flowers and grass and landscaping.
