Popular with many of our customers! HANNA pH Buffer Solution is standardized for reliable results and suitable for a wide range of applications. Available separately in 500 ml bottles.

DIRECTIONS FOR USE:

Step 1: Set the instrument into calibration mode either by pressing the CAL button or pressing and holding down the ON/OFF button until CAL appears on the LCD screen.

Step 2: ALL HANNA meters will need to be calibrated to pH 7 (HI 7007) first. Place the electrode into the liquid so that the bottom inch of the electrode is submersed. While the meter is waiting for the reading to stabilize a clock symbol will flash. Once the meter has reached a stable reading it will automatically calibrate itself.

Step 3: Rinse the electrode under tap water (or deionized water) and then place the electrode into the pH 4 (HI 7004). Once the meter has reached a stable reading it will automatically calibrate itself.
