  • Calibration timeout.
  • PC Connectivity via USB.
  • GLP.
  • Intuitive keypad.
  • Carry case and accessories.

About the FC2023 electrode

Food products can provide a number of challenges for the person that needs to measure pH. Food products tend to be solid, semi-solid or as a slurry with a high content of solids. All types of samples will coat the sensitive glass membrane surface and/or clog the reference junction. The FC2023 supplied with the HI-98161 is designed specifically for measuring pH in food. It has a conic tip shape for easy penetration, open junction that resist clogging, and a Polyvinylidene fluoride (PVDF) food grade plastic body that is resistant to most chemicals and solvents, including sodium hypochlorite. It has high abrasion resistance, mechanical strength and resistance to ultraviolet and nuclear radiation. PVDF is also resistant to fungal growth. The FC2023 is an ideal general-purpose pH electrode for food products that connects to the HI-98161 with a quick-connect, waterproof DIN connector, allowing for a secure, non-threaded attachment. See spec below.

CAL Check™ feature

The HI-98161 has the Hanna unique CAL Check™ feature that alerts the user to potential problems during the calibration process. This is a very important for the food processor since it is likely that the probe will be coated with the solids found in the food product being measured. This coating can easily lead to errors in pH measurement. By comparing previous calibration data to the current calibration, the meter will inform the user, with display prompts, when the probe needs to be cleaned, replaced, or if the pH buffer might be contaminated. After calibration, the overall probe condition is displayed on screen as a percentage from 0 to 100% in increments of 10%. The probe condition is affected by both the offset and slope characteristics of the pH electrode, both of which can be found in the GLP data.


Pressing the AutoHold virtual key in measurement mode, the meter will freeze and automatically log a stable reading. An “out of calibration range” warning can be enabled that will alert the user when a reading is not within the bracket of calibrated pH values.

Help menu

A contextual help menu based on the screen that is currently being viewed can be accessed at any time by the press of a dedicated button.

Log-on demand

The log-on-demand mode allows the user to record and save up to 200 samples. The logged data, along with the associated GLP data, can then be recalled or transferred to a PC with Hanna’s HI-920015 micro USB cable and HI-92000 software for traceability in record keeping for specific product batches. GLP data includes date, time, calibration buffers, offset, and slope, and is directly accessible by pressing the dedicated GLP key.

LCD screen

The high contrast, graphic LCD screen is easy to view outdoors in bright sunlight as well as in low-lit areas with the backlight. A combination of dedicated and virtual keys allows for easy, intuitive meter operation in a choice of languages.

Carry case

The compact, durable HI-720161 carrying case is thermoformed to hold all necessary components for taking a field measurement, including the meter and electrode, beakers, buffer solutions and cleaning solutions.

Setup screen

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


pH calibration features detailed CAL Chec™ messages. Users are guided through the calibration procedure with step-by-step on-screen instructions.


Comprehensive GLP functions are directly accessible by pressing the GLP key. Calibration data, including: date, time, offset, slope and buffers used in the last calibration can be reviewed.
