HANNA Instruments LogoHANNA® manufactures quality pH buffer solutions for a variety of applications. ALL are standardized against NIST reference solutions. Available separately in 500 ml bottles.

GROWER'S TIP (Calibrating your pH Meter):

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 Buffer Solution (HI 7007) first. Place the electrode into the solution 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 Buffer Solution (HI 7004). Once the meter has reached a stable reading it will automatically calibrate itself.
