3-in-1 pH Monitor: Wall-mountable rechargeable continuous monitor tester is widely used to measure the pH/ORP/Temperature of water. clear LCD with backlight, 3 results displayed simultaneously. can online monitoring for a long time. pH electrode We use the international common BNC-Q9 plug, the pH probe can be replaced. In case of wearing and tearing after a period of time, you can just change the electrodes instead of the whole unit.

Calibration pH Tester: pH Monitor test temperature in ℃/℉(switchable unit), automatic temperature compensation. pH calibration powders and ORP calibration powders are included in the set. calibrates easily and offers safer and more precise measurements. each set of products has passed the calibration liquid test function qualified before shipment.

Water Quality Tester with Output Power Relay: Plug in your own device (e.g. oxygen pump, CO2-regulator, O3 ozonizer, or other pH&ORP generation devices) into the corresponding pH or ORP output power socket, and you can set your desired pH ORP value in this monitor controller to trigger your devices to turn on or off.

Easy to Use: Powered by AC Power, ideal for long-term water quality monitoring and controlling. the App can set the upper and lower limits of pH and ORP, which can be set according to your needs. when the value you set exceeds the test range, the application interface will give an abnormal alarm, notifying you of any values exceeding your preset range.

Wide Application: You can use pH monitors to monitor the pH, ORP, and temperature of any type of water, whether in aquariums, swimming pools, spas, laboratories, hydroponics, fish tanks, seawater, aquaculture, ponds, etc, or in-situ water analysis programs. easy to use and provides an instant display of results.

YIERYI 3-in-1 pH monitor, used for online monitoring the pH/ORP, WiFi Tuya APP controlled, widely used in aquariums, swimming pools, laboratories, hydroponics, fish tanks, aquaculture, ponds, etc.

PH is an accurate acidic/alkaline measurement of water. ORP is an accurate measurement of the redox potential of water.
Fuse protection: When the current exceeds the normal range, the circuit will automatically cut off, providing protection.

pH ORP Controller

Can view current and historical data on the APP, and connect multiple devices simultaneously.

WiFi Online Control Monitor
Data can be recorded, saved, and exported.
Compatible with iOS and Android devices.

3 in 1 pH ORP TEMP Monitor
3 Points pH calibration (pH 7.0 / pH 4.01 / pH 10.01) ORP calibration (256mV).

pH CALIBRATION
1.Two calibration modes: 6.86/4.00/9. 18 (Asian standard) and 7.00/4.00/10.01 (EU standard)can be chosen in settings.Dissolve the chosen powders in different cups with 250ml, distilled water.
2. Put the electrode into 6.86 solution, Wait for the value to stabilize, press [CAL] for 5 seconds and the screen will display "CAL" , release the button and waitfor 6.86 toflash 3 times to complete 6.86 calibration.
3.Put the electrode into 4.00 solution, Wait for the value to stabilize, press [CAL] for 5 seconds and the screen will display "CAL",release the button and waitfor 4.00to flash 3 times to complete 4.00 calibration.
4.Putthe electrode into 9,18 solution, Wait for the value to stabilize, press [CALI for 5 seconds and the screen will display "CAL"，release the button and wait for 9.18 to flash 3 times to complete 9.18 calibration.

NOTICE
1. It is factory calibrated and can be used directly.
2. Gently stir several times to make sure there are no air bubbles around the electrode.
3. Do not disassemble the instrument without permission to avoid damage.
4. During the test, it is normal for the probe to generate resistance when it encounters air and the value jumps.
5. Be careful not to impact or cllidlel the electrode bulb, otherwise it will cause rupture.If damaged, the electrode needs to be replaced.
6.To download the app, search for Tuya app in Google Store or Apple Store. After downloading, connect the phone according to the steps of the manual.
