Hanna HI1131B Laboratory pH Electrode
Combination pH electrode with ceramic junction engineered for beer testing and general laboratory applications
Purpose-built electrode design for reliable pH measurement in beer and lab environments
Ceramic Single Junction
15-20 Β΅L/h flow rate prevents clogging in high-protein and turbid samples like beer wort and finished beer
Silver/Silver Chloride Reference
Single Ag/AgCl reference system with 3.5M KCl + AgCl electrolyte delivers stable readings across pH 0-13 range
Spherical Glass Tip
9.5mm diameter spherical tip shape provides durability and consistent contact with sample surfaces
Standard BNC Connection
1 meter coaxial cable with BNC connector fits Hanna and most laboratory pH meters

Works with Hanna pH meters and most laboratory instruments
The HI1131B electrode connects to any pH meter with a standard BNC input, including Hanna portable and benchtop meters. Designed specifically for brewery quality control labs and general laboratory use where beer, wine, or other viscous and turbid samples require testing. The ceramic junction resists fouling better than glass junctions in protein-rich liquids.
Beer Optimized
Junction flow rate prevents clogging in wort and finished beer
Lab Versatile
General purpose design handles most aqueous samples
Universal Fit
BNC connection works with most benchtop pH meters
Durable Glass
Spherical tip resists breakage during routine handling
