Digital PH Meter Sensor Tester

$29.99 $39.99

Easily measure the pH level of your drinking water, pool and aquarium in seconds. Featuring an eletrode detector, it accurately displays the PH level to the 100th decimal.

Ensure the pH level of the water you're drinking is appropriate and healthy with our pH meter. With differing water quality, some source of water can be harmful for your health.

  • Easy to Use: Submerge the pH meter in the solution and get back instant results, clearly displayed in the LCD screen.
  • Calibrated Results: Features a built-in calibration function that can be used with the two included buffer powders. Make sure to get accurate results.
  • Highly Accurate: Its electrode detector displays back accurate results, with an accuracy of ±0.1 pH and with a precision to the 100th decimal.
  • Practical Application: Practical to use in aquariums, in the fishing industry, swimming pools, spas, school laboratories, food & beverages, drinking water, etc.
  • Compact and Portable: It is pocket sized, making it easy to carry anywhere.

**Instructions included

How to use:

  1. Remove protective cap.
  2. First, rinse the electrode with distilled water and suck it with filter paper.
  3. Turn the meter on by pressing the “ON/OFF” key.
  4. Immerse the pH meter electrode in the solution to be tested (should not be over the immersion line).
  5. Stir gently and wait around 30 seconds till the reading stabilizes.
  6. After finishing, clear the electrode with pure water, turn the meter off by pressing the “ON/OFF” key.
  7. Always replace the protective cap after use.

Calibration:

  1. Turn on PH meter
  2. Dissolve each buffer solution in 250ML of distilled water
  3. Immerse the electrode into the PH 6.86 solution,(under the temperature of 25)
  4. Press the “CAL”(calibration)button for 5 seconds and release
    • The display will start flashing 6.86
    • Wait until the display stops flashing.
    • Rinse the electrode with distilled water and dry it with filter paper.
  1. Immerse the electrode in PH 4.00 solution,
    • Press the “CAL” button for 5 seconds, then press and release immediately the second time
    • Reading will start flashing 4.00
    • Wait until the display stops flashing
    • Rinse and dry the electrode with distilled water as before.
  1. Place the meter back to the buffer solution to test calibration. If incorrect, please repeat the calibration
  2. If the approximate PH of your test solution is known to be above 7.0, calibrate the meter using 6.86 and 9.18 solution. To do this, please follow the calibration chart, The third step is the calibration method for 9.18 points.
