Features pH Meter
- Easy to Use: Simply immerse the pH meter electrode in the solution to be tested. The readings are displayed quickly on a large LCD screen.
- Wide Application: Ideal for aquariums, fishing industries, swimming pools, spas, school laboratories, food and beverage testing, and drinking water.
- Auto-Calibrated: Built-in calibration with two buffer powders (included). Simply press a button to calibrate. The pH meter is factory calibrated and ready to use.
- Fast and Accurate Results: No need for color charts or test strips. Provides reliable and precise results quickly.
- Compact and Portable Design: Lightweight and compact design makes it pocket-friendly and easy to carry anywhere.
Operation Instructions for pH Meter
- Remove the protective cap.
- Rinse the electrode with distilled water and dry it with filter paper.
- Turn on the meter by pressing the “ON/OFF” button.
- Immerse the electrode in the solution to be tested (ensure the solution does not go beyond the immersion line).
- Stir gently and wait for approximately 30 seconds until the reading stabilizes.
- After use, clean the electrode with pure water and turn off the meter by pressing the “ON/OFF” button.
- Always replace the protective cap after use.
Calibration Instructions
- Turn on the pH meter.
- Dissolve each buffer solution in 250 ml of distilled water.
- Immerse the electrode in the pH 6.86 solution (at a temperature of 25°C).
- Press the “CAL” button for 5 seconds and release. The display will flash 6.86. Wait until it stops flashing.
- Rinse the electrode with distilled water and dry it with filter paper.
- Immerse the electrode in the pH 4.00 solution. Press the “CAL” button for 5 seconds, then press and release it immediately for a second time. The display will flash 4.00. Wait until it stops flashing.
- Rinse the electrode with distilled water and dry it as before.
- If the test solution’s approximate pH is above 7.0, calibrate the meter using 6.86 and 9.18 solutions by following the same procedure.
