HI-9126 Waterproof pH/ORP Meter with CalCheck information
Hanna's extended description
The HI-9126 portable pH/ORP includes Hanna's exclusive Calibration Check™ technology. 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 electrode, Calibration Check™ warns users that maintenance may be needed.
This portable meter utilises the HI-1230B double junction pH electrode. The double junction helps to minimise junction contamination for consistently accurate results. The HI-9126 can also measure ORP using optional probes as well as storing and recalling readings at the touch of a button.
Key features
