Hanna Instruments Professional hand-held pH/°C meter for beer HI98167
This robust and waterproof hand-held pH meter for the brewing process impresses with its titanium body and integrated temperature compensation. Precise pH measurement is essential, especially in professional breweries where the mash contains a high proportion of solids and sugar. The special design reduces interference and ensures reliable results in various process phases. Experience similar to that of the Hanna Instruments Edge HI2002 shows that the combination of a durable electrode and easy handling plays a decisive role in accurate analyses.
Performance features and design
For use in the brewing industry, this measuring device offers numerous functions that are suitable for both laboratory and production tests. The IP67 standard design protects the device from moisture and dust, making it easy to use in demanding conditions. In addition, the supplied carrying case is designed to fit perfectly so that everything you need is bundled together.
The FC2143 electrode with titanium body is particularly noteworthy:
- Heat resistance at temperatures up to 80 °C for measurements in hot mashes
- Built-in amplifier to minimize signal interference.
- Fast Quick Connect DIN connection without screw connections.
- Flat pH sensor surface that can be cleaned quickly.
- Refreshable textile diaphragm against deposits, which prevents unstable measurements.
Compared to conventional measuring systems, there is less need to worry about interference or measured value drift. The compact design and clear graphic LCD increase user-friendliness. In addition, the device can be calibrated to up to five points with standard or user-defined buffers. The integrated processor automatically compensates for measurement errors caused by temperature fluctuations, ensuring reproducible results.
CAL check and GLP documentation
Starch residues from the mash can affect the electrode glass, especially during the brewing process. The patented CAL Check function continuously monitors the calibration data and compares it with previous values. Clear warning messages indicate immediately whether the electrode needs to be cleaned or replaced. During operation, the device displays the overall condition of the electrode as a percentage and warns of any irregularities.
In addition, all relevant measurement and calibration data is recorded in a GLP protocol. Up to 200 data records can be saved if required and retrieved via the USB interface. This allows brewers to keep a close eye on their process parameters and enables them to quickly identify and analyze possible fluctuations.

For optimum results, the device also protects against noise and signal interference with a special grounding pin. This integrated matching pin in the titanium body prevents measurement errors from creeping in unnoticed due to electrical interference.
Application examples in the brewery
- pH control of the mash: Thanks to the temperature resistance of the electrode, the measuring device is ideal for monitoring changes in the mash and making corrections in good time.
- Monitoring during wort cooling: The glass surface is particularly sensitive at high temperatures, but the robust titanium body protects the electrode from damage.
- Fermentation process control: With precise pH data, yeast activity can be better controlled, keeping aromas and alcohol content stable.
- Quality control of the finished beer: The pH balance determines shelf life and taste, especially during filtration or further post-treatment.
Frequently asked questions
How often should the electrode be cleaned?
For intensive use in the brewing process, regular cleaning after each series of measurements is recommended. The CAL Check function also indicates when cleaning is urgently required.
Which buffers should be used for calibration?
There are seven standard buffers (pH 1.68; 4.01; 6.86; 7.01; 9.18; 10.01; 12.45) to choose from. Brewers often benefit from pH 4.01 and 7.01 as they are relevant for the mash and beer area.
Is the device also suitable for outdoor measurements?
Yes, the IP67 protection class allows measurements to be taken outdoors and provides reliable protection against moisture and dust.
Can the measuring device be integrated into existing documentation processes?
The PC software supplied enables the stored values to be read out. This means that the device can be easily integrated into existing quality assurance and documentation processes.
Conclusion
This hand-held pH meter with its electrode specially designed for the brewing process offers an impressive combination of durability, precision and user-friendliness. Thanks to innovative functions such as CAL Check, versatile temperature compensation and a robust titanium housing, it is of interest to all brewers who require reliable pH values in the mash and during fermentation processes. The simple configuration and large data memory also ensure complete documentation, which is a decisive factor for consistent quality and efficiency in the professional brewing industry.
