Accurate pH meter for aquarium and pond water
- Measures pH from 0-14 with a precision up to 0.02 units.
- The instrument has an automatic calibration function for both 1-point (6.86) and 2-point calibration (4.00 – 9.18).
- Calibration powders are included.
- Auto shut-down after 5 min.
Usage
- Remove the protective cap before use.
- Press the on/off button.
- Dip the pH meter in the water up to the immersion line. The meter is NOT waterproof, never dip the meter into the water beyond the immersion line.
- Wait approximately 30 seconds until the measurement is numerically stable.
- Read the pH value of the water.
- Rinse the electrode with distilled water, dry with a tissue and replace the cap.
- Avoid heat and direct sunlight.
1 point Calibration 6.86
Calibration accuracy is ± 0.1 pH
- Dissolve the pH 6.86 buffer powder in a cup containing 250 ml of distilled water of 25°C.
- Dip the pH meter into the water with the pH 6.86 solution and wait for about 30 sec.
- Press and hold the CAL button for 5 sec.
6.86 will start to flash on the display. - When the flashing stops, the pH meter is calibrated.
Rinse the electrode with distilled water, dry with a tissue and replace the cap.
1 point Calibration 6.86
Calibration accuracy is ± 0.1 pH
- Dissolve the pH 6.86 buffer powder in a cup containing 250 ml of distilled water of 25°C.
- Dip the pH meter into the water with the pH 6.86 solution and wait for about 30 sec.
- Press and hold the CAL button for 5 sec.
6.86 will start to flash on the display. - When the flashing stops, the pH meter is calibrated.
Rinse the electrode with distilled water, dry with a tissue and replace the cap.
2 point Calibration 4.00 and 9.18
Calibration accuracy is ± 0.02 pH
- Dissolve the pH 4.00 buffer powder in a cup containing 250 ml of distilled water of 25°C.
- Dip the pH meter into the water with the pH 4.00 solution and wait for about 30 sec.
- Press and hold the CAL button for 5 sec.
6.86 will start to flash on the display. - Immediately press the CAL button briefly.
4.00 will flash on the display. - Wait until the flashing stops.
Rinse the electrode with distilled water
- Dissolve the pH 9.18 powder in another cup.
- Now dip the pH meter in water with the pH 9.18 solution and wait for about 30 sec.
- Press and hold the CAL button for 5 seconds.
6.86 will start to flash on the display. - Immediately press the CAL button briefly.
4.00 will flash on the display. - Immediately press the CAL button again.
9.18 will now flash on the display. - When the flashing stops, the pH meter is calibrated.
Rinse the electrode with distilled water, dry with a tissue and replace the cap.
