Features HD Display: Portable digital display EC soil analyzer with high definition backlight display, which provides clear and intuitive reading at night. High Accuracy: The EC measurement range is 0.00‑10.00mS/cm, and the TEMP measurement range is ‑30.0℃‑80.0℃, with high measurement accuracy and high resolution. Purpose: It can measure the index of soil water soluble salt to determine whether the salt ions in the soil restrict the growth of crops. Calibration And Temperature Compensation: EC measurement supports single point (1413us/cm) calibration and automatic temperature compensation (‑30℃‑80℃). Function: Replaceable electrodes, low battery warning, automatic shutdown function, IP67 waterproof, suitable for gardening and agriculture.
