Barksdale Water Quality Tester, ORP PH TDS Temp EC Salinity SG 7 in 1, Accurate LCD Digital Water Meter Pen with Detection Powder, for Drinking Water, Aquariums

How to Calibrate the PH Meter?

1. Before calibration, pH4 00/pH6. 86/pH9. 18 add the buffer powder to a beaker with 250 ml distilled water and stir until the powder is completely dissolved.

2. Press the on/off button to turn on the instrument; Adjust to pH mode.

3. Put the electrode into pH4 00/pH6. 86/pH9.18 in the standard solution, wait for the reading to stabilize.

4. Press and hold the mode/CAL button and release it after 5 seconds;

5. Until the readings of pH4.00/pH6.86/pH9.18 are no longer flashing, the calibration of pH4.00/pH6.86/pH9.18 is completed.

How is the water quality, test it before you drink, water quality test pen is a simple portable water quality test tool, used to test the conductivity of water or water pH, to determine the water purity	Table salt: 0.01-25% The appropriate level of salt intake for the human body is 0.900%. The World Health Organisation recommends a daily intake of 6g of salt for the general population	0RP: 0-±999mV ORP values for freshwater fish tanks are approximately 230m-260mV ORP value for seawater fish tank is approx. 350m-450mV

Automatic Calibration Available in 1, 2 and 3, three different calibration modes with automatic buffer identification.
