Features:<br> 1. Large LCD display: soft light without blinding, can easily cope with various environments, display PH value and temperature value at the same time<br> 2. Puncture type electrode: can measure PH value of soft solids, such as soil, cheese, meat, etc. Electrode can be replaced, more convenient maintenance<br> 3. Data synchronisation display: PH meter data will be synchronised to APP, multiple data can be displayed at the same time, convenient and fast<br> 4. Self-setting maximum or minimum measurement value: set the maximum or minimum PH limit according to the user's requirements If the test result is out of range, the value will be displayed in red<br> 5.
