Features:

Widely used to test the pH / Temperature / TDS (Total Dissolved Solids) of water.
With relay output power socket, you can control the pH value according to your requirements.
You can replace the fuse easily and fast with external replacement. Detachable and replaceable pH electrode.
With power plug for air outlet stone, oxygen pumps, carbon dioxide regulators, solenoid valves and other pH control devices.
Test the TDS with both PPT and PPM units at will.
Easy calibration of pH/TDS with just a mini-screwdriver and automatic temperature compensation.
Clear LCD with backlight, 3 results displayed simultaneously. Easy to use and provide instant display of results.
Test temperature in ℃ / ℉(switchable units) and can online monitor and control pH for a long time.
Apply in water sources, soil-free growing, aquarium, hydroponics, laboratory, spas, environment water, swimming pools, water purification systems, etc.

Operation method:

1. Connect the AC power supply (ensure the core).

2. Connect the ph temp temp electrode to the relevant electrode socket.

3. Remove the protective cap, clean the electrode with distilled water, put the pH electrode, tds electrode, and temperature electrode into the liquid to be measured. Stir gently. Wait until the number is stable before reading the final value.

PH calibration

1. Immerse the electrode in a standard phosphate buffer solution of pH 6.86 (at 25°C) and shake the electrode gently.

2. Adjust the ph7 trimmer with a screwdriver until the buffer solution value corresponding to the measured temperature is obtained.

3. Clean the electrode. Immerse the electrode in the standard ph4.01 buffer solution, and adjust the ph4 trimmer with a screwdriver until the buffer dissolution value corresponding to the measured temperature is obtained.

4. Clean the electrode. Immerse the electrode in the standard pH9.18 buffer solution and stir gently until the sieving value is stable. If the error of the displayed value is within the allowable range, the calibration is complete. If not, please repeat 2.3.

TDS calibration

1. Press "Mode" to select "pptpt mode", then immerse the tds electrode in 6.44ppt standard buffer solution and shake it gently.

2. When the displayed value is stable, adjust the "ppt" at the bottom until it displays 6.44ppt. Wash the electrode with distilled water and dry it with filter paper.

3. Immerse the equipment in the standard 1382ppm solution and press "Mode" to select ppppm mode. When the displayed value is stable, adjust from the bottom ppppm. Until it shows 1382ppm.
