PH Meter using protocol

P^H Meter using protocol

1.     Make available 3 A water in rinsing bottle, paper towel, a beaker and buffer solution (P^H 7.00 and P^H 9.21)

2.     Turn on the machine.

3.     Uncap the probe and rinse it with 3A water.

4.     Dry the probe by using paper towel but not keep it dry for long time because it will damage the probe.

5.     Submerge the probe in buffer (P^H 7.00) immediately. Press the calibration Button.

6.     Take out the probe from buffer (P^H 7.00) and rinse it with 3A water.

7.     Dry the probe with paper towel and submerge the probe in buffer (P^H 9.21) asp.

8.     Press the calibration Button and read the slope. Write down the slope on record book.

9.     Take out the probe from buffer (P^H 9.21) and rinse it with 3A water.

10.    Dry the probe with paper towel and submerge the probe in target liquid if it is not ready put it 3A water and ready the target liquid. When the target liquid is ready, take out the probe and dry it with paper towel and submerge it in target liquid.

11.    Press the Read Button and read the P^H

12.    If require adjust the P^H by using 10N NaOH and con. HCl (Wear gloves before  using them)
