* LCD displays pH value and temperature value, large size screen display, easier to read data
* Electrode and controller as unibody design, easy to carry and use
* Automatic temperature compensation, to ensure precision under the condition of the temperature change (except external electrode)
* Replaceable electrode, use the industrial technology, teflon fluid to do the electrode, soil resistance is better, Data react faster
* 4pcs button battery as power - ultra-low power consumption, easy to replace with special rubber trap
* Imported chips, using single-chip microcomputer technology, more stable performance
* Hold function, automatic correction
