PH-803W is a new digital wifi monitoring acid-base and redox controller which can measure and display the pH value and redox value (ORP) at the same time. It has 2 BNC electrodes (pH and redox) and 2 output sockets. It has fast response speed and easy pH calibration. The two electrodes are detachable and can be easily replaced at any time without the need to purchase and replace the entire device. At the same time control other equipment related to pH and ORP to adjust pH and ORP value in liquid.

Calibration：

Calibration pH:

A. In pH6.86 Calibration solution
1. Connect AC power. Immerse the ph electrode in a pH6.86 buffer solution and shake it gently until the reading stabilizes.
2. Long press [b], until the “pH” indicator flashes. PH6.86 is displayed on the first line.
3. (1) Short press [a] to exit current mode if ph6.86 calibration is not performed. Then the device returns to measuring mode.
(2) Short press [c] to complete the pH 6.86 calibration when the second line reading is stable if the pH6.86 calibration is performed. The device then automatically returns to measuring mode.
4. The pH6.86 calibration is complete.

B. In pH4.00 Calibration solution
1. Connect the AC power. Immerse the ph electrode in a pH 4.00 buffer solution and shake it gently until the reading stabilizes.
2. Long press [e], until the “pH” indicator flashes. pH 4.00 is displayed on the first line.
3. (1) Short press [a] to exit current mode if pH 4.00 calibration is not performed. Then the device returns to measuring mode.
(2) Short press [c] to complete the pH 4.00 calibration when the second line reading is stable if the ph4.00 calibration is performed. The device then automatically returns to measuring mode.
4. The pH 4.00 calibration is complete.

ORP calibration:

This meter has been precisely precalibrated for mV range at the factory. And there is no need for users to calibrate.
