Professional Portable Beer pH Meter

This meter is supplied with a pH electrode specifically designed for use in the brewing process.

The FC2143 is a pH electrode with internal temperature sensor and titanium body ideal for measuring the pH of mash, wort, and the finished product.

The meter is provided with a series of new diagnostic features which add an entirely new dimension to the measurement of pH, by allowing the user to dramatically improve the reliability of the measurement.

 

Key features:

• Waterproof – IP67 rated waterproof, rugged enclosure
• CAL Check - alerts users to problems during calibration including dirty/broken electrode, contaminated buffer and overall probe condition
• Automatic or manual temperature compensation – pH sensors incorporate a built-in temperature sensor
• Calibration – up to a five-point calibration with seven standard buffers and five custom buffers
• Approximately 200 hour battery life – Powered by 4 x 1.5V AA batteries
• Clear display – Dot matrix display with multifunctional virtual keys
• Auto hold – Automatically holds the first stable reading on the display
• Calibration timeout – Alerts when calibration is due at a specified interval
• Connectivity – PC connectivity via opto-isolated micro-USB with HI-92000 software
• GLP – GLP data provides data from previous calibrations to ensure Good Laboratory Practices are met
• Intuitive Keypad – Important and often used functions such as GLP information, help, range, calibration and backlight have a dedicated button

 

Backlit Graphic LCD

These meters feature a backlit graphic LCD with on-screen help. The graphic display allows for the use of virtual keys to provide for an intuitive user interface.

 

Calibration timeout

Alerts when calibration is due at a specified interval.

 

pH Calibration

Choose from seven standard pH buffers and five custom values to obtain up to five point calibration and achieve high precision readings with a 0.001 pH resolution and a pH accuracy of ±0.002.

 

Enhanced calibration

At “out of calibration range” warning can be engaged to keep the user informed of the current calibration and help to avoid performing measurements that are out of the bracketed range.

 

GLP

Comprehensive GLP functions are directly accessible by pressing the GLP key. Calibration data, including date, time and calibration values are stored with logged data for retrieval at a later time.

 

Data Logging

The log-on-demand feature allows users to store up to 200 samples that can be later transferred to a PC with the HI-920015 USB cable and HI-92000 software.

 

Automatic Temperature Compensation

pH sensors incorporate a built-in temperature sensor in the tip of the electrode for a fast and accurate temperature compensated value.

 

Intuitive keypad

The fitted rubber keypad has dedicated keys for many important and often used functions. These meters also feature two virtual soft keys that navigate the user through setup and logging of data. The interface is intuitive for any user’s level of experience.

 

Auto hold

Pressing AutoEnd during measurement will automatically hold the first stable reading on the display.

 

Dedicated help key

Contextual help is always available through a dedicated HELP key. Clear tutorial messages and directions are available on-screen to quickly and easily guide users through setup and calibration. The help information displayed is relative to the setting/option being viewed.

 

Setup screen

Our extensive setup screen features a host of configurable options such as time, date, temperature units and language for help screens and guides.

 

PC Connectivity

Logged data can be transferred to a Windows compatible PC with the included HI-920015 micro USB cable and HI-92000 software.

 

Long battery life

The display of the meter has a battery icon to show the remaining power. The meter uses four 1.5V AA batteries that provide up to 200 hours of battery life.

 

Application importance

The measurement of pH during the beer making process is important due to the effect it has on enzymatic activity in the mash, yeast activity in fermentation, and the incorporation of flavouring components.

Monitoring and controlling the pH allows for a consistent flavour profile and ensures a stable product.

The brewer is faced with a number of challenges when measuring pH. The mash has a high content of semi-solids, and sugars are formed from the conversion of starch by enzymatic activity.

Both can pose problems, including coating the glass and clogging the junction. The mash and cooled wort after boiling are typically above room temperature, which leads to the degradation of the sensitive glass.

To overcome these challenges, the HI-98167 beer pH meter is supplied with a uniquely designed titanium bodied pH electrode.

 

Each instrument is supplied with:

• FC2143 Titanium body, flat tip, pre-amplified pH electrode with internal temperature sensor
• HI-700682 Electrode cleaning solution for brewing deposits, (2 sachets)
• HI-720161 Hard carrying case
• HI-920015 USB cable
• pH 4.01 & 7.01 Buffer solutions (230 mL each)
• 100 mL Beaker (2)
• 1.5V AA Batteries (4)
• Instruction Manual and Quick Reference Guide
• Instrument Quality Certificate

 

About the FC2143 Titanium bodied pH and temperature electrode for beer

The FC2143 pH electrode is a flat tip pH sensor made with specialising glass to provide a long life when measuring temperatures up to 80°C. A built in temperature sensor compensates for temperature variations. The probe has a built in amplifier and a titanium body that acts as a matching pin to reduce noise as a result from the effect that humidity has on probe connection to the meter. The FC2143 connects to the HI-98167 with a quick-connect, waterproof DIN connector, allowing for a secure, non-threaded attachment.

Titanium Body

A pH measurement is a very sensitive voltage measurement that is susceptible to interference. To reduce this susceptibility, the titanium body serves as a matching pin. A matching pin is a differential measurement technique used to eliminate electrical noise in the measurement system.

Flat tip pH sensor

The flat tip sensor allows for easy cleaning of the pH sensing surface as solids, from mash and cooled wort collect on the surface.

Quick-Connect DIN

This secure waterproof connector allows for a single cable to be used for both pH and temperature measurements.
