4-20mA Automatic Dosing pH ORP Controller for Water

The APX1-C1 online pH ORP Controller is an intelligent water analysis instrument. It is the most basic configuration and cost-effective instrument developed and produced by Delfino. The function of the controller is not only to measure pH or ORP value, but also to realize the output of data, it has a current output of 0/4-20mA. In addition, the pH analyzer is capable of controlling dosing with two configurable relays. This pH orp controller is powered by a wide voltage, 100~240V or 18~36Vto prevent the influence caused by voltage instability.  The protection grade of the enclosure is IP66, which can prevent the intrusion of external dust and rain.  The screen is a 3.2-inch LCD screen, and the user can set the contrast and brightness. The menu interface also has a password that can be set to prevent misoperation. For the calibration of the pH sensor, the pH ORP controller support three-point calibration, and the user can modify the value. The controll…
