2 In 1 PH/Temp PH Tester Water Quality Analyzer Desktop Automatic Calibration Acidity Meter for Laboratory Aquarium Pool EU Plug

The  PHS-3C  pH  meter  is a portable microprocessor-based pH/temperature meter. The  handy  key  board  for  the  selection  of  the  various  functions. The possibility  of  automatically correcting  errors  in  measurement  due  to temperature  and  the  extreme  simplicity  of  regulation  all  serve  to  permit  a  rapid  and reliable  execution  of  calibration  and  measurement.The  display  on  the  front  panel  reveals  the  temperature  pH readings  taken  by  the  instrument. The  instrument  comes  supplied  with  a  combined  pH  electron  and  a probe for  the  measurement  and  compensation  of  the  temperature.

Plug: EU Plug 1.Connecting AC power supply. Turn on the meter by"ON-OEF" switch located back ofthe instrumen 2.Connect the electrode to the iack back of the instrument 3.Remove the protective cap of electrode. Put the electrode into the measured solution to be tested.

1.Pour asmall quantity of pH6.86. pH4.00 and oH9.18 solution into clean beakers. 2.For a particularly accurate calibration, itis advised to use two beakers for each buffer solution; the first is to be used forrinsing the electrode, the second is to be used for the calibration. In this way, the risks of contaminating the buffer solution are reduced to a minimum 3.Switch on the instrument. 4.lmmerse the electrode in a pH6.86 buffer solution, and gently shake it until the reading to stabilize 5.Press the button "CAL" until the calibration Indicator is light.Then press "PH7" until the display shows "6.86". Rinse the electrode with distilled water. 6.lmmerse the electrode in a pH 4.00 buffer solution, and gently shake it until the reading to stabilize 7.Press the button "CAL" until the calibration Indicator is light.Then press "PH4" until the display shows "4,00". Rinse the electrode with distilled water. 8.lmmerse the electrode in a PH9.18 buffer solution. Waiting for the reading to stabilize until the display reading exact 9.18. 9.The calibration of the instrument's pH range is now complete
