Hach Intellical PHC281 Water Quality Laboratory Refillable pH Electrode, 1 m Cable
Intellical PHC281 Water Quality Laboratory Refillable pH Electrode, 1 m Cable
ntellical PHC281 is a digital combination pH electrode with built-in temperature sensor. The PHC281 is a pH refillable probe made for difficult samples. This laboratory pH electrode is shockproof with its Zeonor plastic body protecting down to the glass bulb sensing element. The electrode is available with a 3 or 1 m cable. The PHC281 refillable pH electrode has a high electrolyte flow rate and a large open junction ideal for difficult samples, such as Low Ionic Strength (LIS), Ultrapure, dirty samples and samples with high solids content. The PHC281 is not suitable for use with organic solvents. A 59-mL bottle of 2.44 M KCl Electrode Filling Solution is included with the probe.
Benefits
