Hach Sension+ PH3 Benchtop pH Meter

The Hach Sension+ PH3 is a single-parameter (pH) benchtop pH meter designed for pH, mV, ORP/Redox, and temperature measurement on laboratory worktables. Its simple keyboard interface and backlit graphical LCD display deliver rapid results during daily routine measurements.

The instrument automatically recognizes DIN 19266 (IUPAC) and DIN 19267 (technical) standard buffers, enabling 1–3-point calibration; user-defined custom buffers may also be added. Calibration reminder intervals are adjustable between 1 hour and 7 days, ensuring regular electrode accuracy verification.

With BNC electrode input and Pt1000 temperature probe support, pH accuracy is ≤0.02 pH, while mV/ORP measurement range is ±2000 mV (1 mV resolution). The instrument does not include data logging or PC data transfer; it is therefore best suited for classical laboratory use where results are read directly from the electrode in real time. Designed with IP42 protection rating for normal laboratory conditions; not suitable for field or wet-environment applications.

The set includes an electrode stand and a user-replaceable connector AC power adapter for simple setup. It is a practical solution for education, quality control, and general laboratory departments performing routine pH, mV, and ORP measurement.
