PH-803W Internet of Things PH&ORP Controller

KL-803W is a new wifi monitoring digital acid-base and redox controller, which can measure and display pH value and redox value (ORP) at the same time. It has 2 BNC electrodes (pH and redox) and 2 Output sockets. It has a fast response speed and easy pH calibration. Both 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 the pH and redox value in the liquid. Accurately, easily and automatically monitor and control pH and ORP values ​​and other control equipment related to pH and ORP. Through strict quality and safety standard certification, it can ensure reliability, stability, long life and trouble-free service life, and is easy to transport, using the dead zone protection function When using or installing the unit, you can choose to wall-mount it or hang it in a solution container. The product types are: 110 V and 220 V.

Has applications and uses:

Fish farms, wine production, swimming pools (bathrooms), laboratories, water treatment, schools and colleges, florists, for analyzing liquids (ph), ponds, various industrial applications, swimming pools, koi, Cois, Boyrel, pond, swimming pool, spa, swimming pool, swimming pool, liquid analysis, orchid breeding, breeding, hemp, cultivation, etc. The correct method allows you to pay attention to the different parameters of the water in the tank at any time! There must be a perfect way to automate and adjust the aquarium controls to eliminate deaths and maintain a healthy water system.

1.Connecting AC power supply (Make sure the correct voltage.)
2.Connecting the PH and ORP electrode into the input terminal socket respectively.
3.Remove the protective cap and observe if the electrodes are clean and complete (note: do not touch the electrodes with your hands).
4.After cleaning the electrodes with distilled water or alcohol, dry the water on the plastic housing and shake off the small droplets on the electrodes, insert the device into the solution under test so that the measuring electrodes are immersed in the solution under test, and the depth of immersion of the electrodes must not exceed the length of the electrodes.
5.Put the electrodes into the measured solution to be tested.
6.Gently shake the device so that small bubbles on the electrodes leave the electrodes and read a stable display number when the value is stable.
7.After use, switch off the power supply, clean the electrodes with clean water and put on a protective cap.
8.It needs to be used for a long time, and the device and electrode should be fixed.


pH calibration:

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

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

ORP calibration:

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