Digital Soil pH Meter for Gardeners Soil Direct pH Tester

Highlights

• High Precision Composite Electrode Sensor: Using a composite electrode sensor to measure quickly and accurately, combined with a zinc alloy blade, it can measure the pH value of soil or bread pastries.
• Three Point Calibration and Automatic Recognition: The instrument has a three-point calibration function, and the sensor automatically recognizes the buffer solution to complete probe calibration.
• Alarm Prompt: When the pH value is below 3.5 or above 12.5 pH, the screen will turn red, indicating that the liquid is approaching strong acids or bases.
• Automatic Temperature Compensation Function: The level of temperature will have a certain impact on pH measurement, and if high accuracy is required, the impact will be even greater. Therefore, the temperature compensation function is necessary.
• Large LCD Display Screen: With backlight screen, dark and strong light environment can also clearly view the value, easy to deal with a variety of environmental measurement.
