R718PA8 is a wireless communication device for the pH values of acid, alkali, and salt solutions. R718PA8 can detect the pH value and temperature of the solution. The body and the pH sensor are connected through the RS485 interface, and the detected data is transmitted to other devices through the wireless network for display
