Feature:
1. The real-time measurement method is adopted, that is, the dual measurement displays the PH value from 0.00 to 14.00 and the ORP value from ?1999 to 1999 mV.
2. Easy to use, you can change the measurement value you want to observe without pressing any buttons.
3. The 2?in?1 PH and ORP controller can measure and display the PH value and oxidation?reduction value (ORP), equipped with BNC socket electrodes and two output power sockets.
4. Powered by AC power, it is very suitable for long?term water quality monitoring and control.
5. The PH controller is made of high?quality ABS material, which is durable and not easily damaged.

How to Use:
1. Plug in the power supply and turn it on.
2. Connect the PH and ORP electrodes respectively.
3. Remove the protective cover. (Do not touch the electrode bulb with your hands to avoid contamination. The glass bulb is fragile and avoid damage by knocking.)
4. After cleaning the electrode with distilled water or alcohol, wipe off the water on the plastic shell and shake off the
