Up to 1500 hours of continuous use with 3 LR44 alkaline batteries (3 more free).

Pool Salt Tester VS Salt Pool Test Strips: When testing with test strips, you have to guess the value of your pool based on the color of the strips; however, salinity meters are simpler, more accurate, and friendlier to color-insensitive users than test strips. Simply place it in the water for a few seconds to get an accurate reading, plus, using enough test strips adds to the cost in the long run.

7 IN 1 Professional Water Quality Tester: The Yieryi 7-in-1 ORP meter accurately measures pH, SALT, EC, TDS, ORP S.G, and TEMP values. With a unique ORP sensor and new electrode design, the anti-interference ability is enhanced, making the measurement more stable and reliable. Have you been struggling to find a saltwater pool tester that is both accurate and easy to use? Our multifunctional ORP tester will tell you the answer.

How to Use the Professional 7 in 1 Water Quality Tester

1. Remove the protective cover downwards

2. Place the probe into the water to be measured

3. Clean and dry the pH probe

4. Close the protective cover upwardsHow to Calibrate the pH Meter?

1. Before calibration, prepare 3 beakers containing separately 250ml of pH 4.00/pH6.86/pH 9.18 standard solution.

2. Rinse the electrode with clean water and wipe it dry. Turn on the pH meter and adjust to pH mode.

3. Immerse the electrode in the pH6.86 buffer solution and wait for the reading to stabilize. Press and hold the “CAL” button for 5 seconds. the screen will display”CAL” and the pH6.86 calibration is complete when pH6.86 flashes 3 times.

4. Rinse the electrode with clean water and wipe dry.

5. Repeat the above calibration steps to calibrate pH4.00 and pH9.18.Once EC calibration is done, salt and TDS calibration done

How to Calibrate the EC/TDS/SALT Meter?

1. Press the “MODE/CAL” button to set the EC mode; the word “uS/cm” will be displayed at the top left of the screen. Put the probe into 1413uS/cm calibration solution and shake it gently.

2. Wait until the reading is stable, then long press “MODE/CAL” for 5 seconds and release, CAL is displayed on the screen, then a value will flash3 times on the screen when the value starts to flash, press “MODE/CAL” button ( if the flashing value is higher than 1413uS/cm ) or “HOLD/TEMP” button ( if the flashing value is lower than 1413uS/cm ).

3. After adjusting the displayed value to 1413uS/cm, then release the button. waiting for the reading to stop flashing, the calibration is finished, rinse off the probe with pure water and replace the protective cap.

4. Repeat the process for the 12.88mS/cm solution, following the same steps. This straight forward calibration ensures your EC meter delivers precise value for various applications.ORP Calibration for Accuracy

How to Calibrate the ORP Meter?

1. Press the ON/OFF button to turn on the meter, take off the protective cap rinse off the probe with pure water and dry it.

2. Press the”MODE/CAL” button to set the ORP mode; the word “mV” will be displayed at the top right of the screen. Put the probe into 256mV calibration solution and shake it gently.

3. Wait until the reading is stable, then long press” MODE/CAL” for 5 seconds and release; CAL is displayed on the screen, then a value will flash 3 times on the screen, when the value starts to flash, press “MODE/CAL” button ( lf the flashing value is higher than 256mV )or “HOLD/TEMP” button (lf the flashing value is lower than 256mV ).

4. After adjusting the displayed value to 256mVthen release the button, waiting for the reading stop flashing, the calibration is finished, rinse off the probe with water and replace the protective cap.
