This digital PH meter package includes:
- One testing device with 2 batteries (AG13/LR44).
- One manual.
- Two sachets of PH buffer powder (Default pH4.01 and pH6.86, or pH6.86 and pH9.18 if required.)
- One plastic box
Remarks:
- ATC, automatic temperature compensation, to revise the error caused by change of temperature.
- The glass electrode is fragile, avoid to be touched or hit, always keep the cap closed while not using, no guarantee for its damage. When the new device is received, the cap may be stuck by chemicals which was not cleaned after the calibration by manufacturer, please pull out forcefully, do not bend or turn the cap, this may be done easily after dipping in the water for a while.
- The device is pre-calibrated by the manufacturer, not necessary to calibrate it before using, but may be done if not correct.
- The calibration is recommended, after 2 to 3 months if the testing has not be done too often, or the accuracy required.
- Calibrate the tester with PH 6.86 buffer powder firstly, then the PH 4.01 or PH 9.18 ones. Should the sample to be tested be acidic, the tester can be calibrated with buffer powder of PH 4.01 and 6.86, while it's alkaline, PH 6.86 and 9.18 ones should be used for calibration. Calibration with these three types of buffer powder is recommended if the tester will be used to test the PH of acid and alkaline.
- Maintenance, should the device not be used for a long period, simply test it with the clean water every half month.
- Sway the device gently against the tested liquid while testing (this may take a while), after the reading is unchanged, then stop and take the reading.
- When replacing the batteries, remove (pull) the battery cap slowly and carefully.
- The pH of tested liquid should be within pH 0 to 14 and its temperature also in 0 to 50 degree, otherwise the detection bulb may be broken if to test the liquid out of these ranges.
- Cautions: Should the batteries are flat (working but reading unclear), the calibration may not be done correctly (error occurs), replace the batteries for calibration.
