pH MEASUREMENTS OPERATIONAL GUIDE For HI 8014: To take a pH measurement simply submerge INITIAL PREPARATION the tip (4cm/1½") of the electrode and a Each meter is supplied complete with a 9V battery. Slide off the ChecktempC (or another accurate thermom- battery compartment cover on the back of the meter, install the eter) in the sample to be tested. - Page 7 Notes: Dip the temperature probe or the pH/°C electrode into the sample and allow the reading to stabilize (a couple of minutes). • In order to take accurate pH measurements, make sure that the instrument is calibrated for pH before use. For HI 931000, to display the measured tem- perature, press and hold the °C key.
