pH/ORP Meter Calibration Solution Buffer Solutions Tester New Arrival IXS

How to Calibrate the pH Meter:1. Rinse the electrode with clean water and wipe it dry. Turn on the pH meter and adjust to pH mode.2. lmmerse the electrode in the pH 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 pH calibration is complete when pH flashes 3times.3. Rinse the electrode with clean water and wipe dry.4.Repeat the above calibration steps to calibrate pHHow to Calibrate the ORP Meter:1.Press ON/OFF button to turn on the meter, the protective cap and 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 222mV 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 fiash, press "MODE/CAL" button ( lf the flashing value is higher than 222mV ) or "HOLD/TEMP" button ( lf the flashing value is lower than 222mV ).4. After adjusting the displaying value to 222mV then release the button, waiting the reading stop flashing,the calibration is finished, rinse off the probe with water.Storage:Buffer solutions should be stored in a dark, cool place (not in the refrigerator and at temperatures no higher than 25C) away from direct sunlight to prevent photochemical degradation. In addition, buffer calibration solutions should be protected from carbon dioxide from the air and stored in tightly closed containers.Colour:As ShownMaterial:plastictype:PH and ORPPackage Contents:1 set x pH MeterOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
