Professional
Portable Meat pH Meter
The
HI-98163 is a rugged, waterproof, Foodcare portable pH meter that
measures pH and temperature using the specialized FC2323 meat pH
electrode with a stainless steel piercing blade. This
professional, waterproof meter complies with IP67 standards. The
HI-98163 is supplied with all necessary accessories to perform a
pH/temperature measurement packaged into a durable thermoformed carrying
case that holds the meters, probes and calibration buffers
securely in place.

In
the meat processing industry, the monitoring of pH is considered to be of
the utmost importance due to its effect on the meat's quality factors
including water binding capacity and shelf life. Upon slaughter,
biochemical processes begin to break down the meat. Glycolysis begins
post-mortem, converting glycogen to lactic acid, reducing the pH of the
carcass. Depending on a number of factors such as type of animal and even
breed, this decrease in pH can take anywhere from a single hour to many.
It is vital to monitor pH during this phase as once the lowest pH value is
reached, the pH will begin to slowly rise, indicating that decomposition
has begun.
The
pH value of meat influences its’ water binding capacity which directly
impacts consumer qualities such as tenderness and color. Lower pH values
result in a lower water-binding capacity and lighter colors. Factors such
as these can be important when considering how to efficiently produce meat
products. For example, when producing dry sausages the meat must have a
low water binding capacity so that it can dry evenly.
The FC2323 is an amplified pH
electrode with a built-in temperature sensor. This probe is
designed with low temperature (LT) glass, a conical tip shape, and
is housed in a food grade PVDF body with a removable, piercing
stainless steel blade. This electrode also features a unique open
junction design in which there a viscolene (hard gel) electrolyte
layer that is free of silver chloride (AgCl) between the sample to
be measured and the internal reference cell. The open junction
design resists clogging and the probe’s conical tip makes it ideal
for pH measurements in meat and semi-solid food samples.
Conical
Glass Tip
The
conical shaped tip design allows for penetration into solids,
semi-solids, and emulsions for the direct measurement of pH in food
products including meat, cheese, yogurt, and milk.
Open
Junction Reference
The
open junction design consists of a solid gel interface (viscolene)
between the sample and internal Ag/AgCl reference. This interface not
only prevents silver from entering the sample, but also makes it
impermeable to clogging, resulting in a fast response and stable
reading.
PVDF
Body
Polyvinylidene
fluoride (PVDF) is a food grade plastic 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.
Besides
being supplied with a unique pH electrode for meat, the HI98163 has the
Hanna's 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.
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 HI920015 micro USB cable
and HI92000 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.
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.
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.
The
compact, durable HI720161 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.

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