pH Electrode for Beer Analysis

FC2143 pH Electrode – Robust Titanium Body with Gel Electrolyte for Brewing

Optimized for Beer Mash and Wort Measurements

The FC2143 is a high-performance, single reference junction pH electrode featuring a titanium body, gel electrolyte, and built-in temperature sensor with amplifier. Designed for precision in beer brewing, it is ideal for monitoring mash and wort pH. This electrode serves as the replacement probe for the HI99151 portable beer meter, providing reliable and consistent readings.

Brewers and laboratory technicians value the FC2143 for its durability, accuracy, and ease of maintenance compared to standard glass electrodes. Its design minimizes interference, ensures long-term stability, and reduces downtime during repeated measurements.

Low Temperature Glass Formulation

The LT glass formulation enables a flat pH-sensitive glass surface, suitable for sample temperatures from 0 to 80°C. This allows accurate measurements in brewing and other food and beverage processes requiring moderate temperature control.

Flat Tip Bulb

The recessed flat tip prevents solids from accumulating on the sensor and simplifies cleaning. Other tip shapes such as conic and spherical are used for penetration or aqueous samples, but the flat tip is ideal for mash with high solids content.

Titanium Body

The titanium body provides robust protection and incorporates a matching pin to minimize electrical noise. This metal construction makes the electrode virtually unbreakable and resistant to environmental interference, ensuring stable voltage measurements even in challenging conditions.

Cloth Junction

The cloth junction allows a portion of the fiber wick to be extended, clearing blockages from solids in mash and wort. This feature enhances electrode longevity and maintains stable readings, a key advantage for high-solids samples.

DIN Connector

Equipped with a quick-connect DIN connector, the FC2143 is fully compatible with the HI99151 meter. Alternative connector types include BNC, screw type, T-type, and 3.5mm, but the DIN connector ensures fast, secure attachment and reliable signal transfer.

Brewery quality control and process analytics

For assessing fermentable sugar concentration during mash preparation, the Hanna Digital Refractometer for Beer provides rapid °Plato readings that help optimize enzymatic conversion and final gravity prediction. Routine spot‑checking of acidity at different production stages can be efficiently performed with the Hanna pH Tester for Beer, a compact tester designed to withstand the rigors of brewery environments. Where broader laboratory capabilities are required, the Hanna Multiparameter Benchtop Photometer and pH Meter offers dual functionality with configurable photometric methods alongside pH measurement to support multi‑parameter quality assessment protocols.
