HI 9124, HI 9125 and HI 9126 Portable pH Meters

The HI 9124 and HI 9125 are heavy-duty, waterproof pH meters that provide laboratory results and accuracy under harsh industrial conditions. HI 9125 can utilise ORP (Oxidation Reduction Potential) electrodes. The HI 9126 includes all of the features of the HI 9125 but includes HANNA‘s exclusive Calibration Check™ technology and a backlit LCD. Calibration Check™ monitors the pH bulb and reference junction of the electrode every time the instrument is calibrated. In the event of a dirty pH bulb, Calibration Check™ prompts the user that additional cleaning may be needed.

Each of these models use the HI 1230B double junction pH electrode. The HI 1230B’s double junction minimises electrode contamination leading to accurate, consistent results and extended electrode life. See www.hannainst.com for more information or email us at [email protected]
