Wine pH Tester - HI981033

All prices are VAT excluded and without shipping costs, unless otherwise stated.

Designed to bring simplicity to pH testing during the wine making process, the HI981033 Wine pH Tester is engineered to solve the challenge of measuring the samples with a high solids content. The built-in probe features a glass body, spherical tip, and Hanna’s Clogging Prevention System (CPS) that resists clogging 20x longer than a standard ceramic frit, making it ideal for measuring the pH during the wine making process.

Wine pH Tester

with specialized probe

The HI981033 Foodcare Wine pH tester is an application specific
designed pH tester for the measurement of pH of grape juice, must,
and wine. This meter offers many advanced features including a
unique Clogging Prevention System Technology (CPS™) that uses a
movable Polyethylene (PE) sleeve for the ability to clear any clogging
of the reference junction. The CPS Technology results in a much longer
life than standard pH testers.

• pH electrode with PE movable sleeve junction (CPS Technology)
The pH electrode of this tester uses a PE movable sleeve
as part of the outer ground glass junction. The PE material
repels solids to prevent clogging. When clogging does occur
the sleeve can be moved and the ground glass surface
cleaned resulting in stable readings and fast response time.
• Refillable
The open junction design of the PTFE sleeve allows for a high
flow rate of electrolyte for a fast and steady reading. The sleeve
can be moved to expose the fill hole for reference electrolyte.
The ability to refill the probe extends the life of the electrode.
• Low temperature (LT) glass
The pH glass tip uses a special low temperature (LT) glass
formulation with a lower resistance of approximately
50 Megaohms compared to general purpose (GP) with
a resistance of about 100 Megaohms. This is beneficial
when measuring samples at lower temperatures in order
to have the ideal resistance for the measuring circuit.

Domed tip
Allows for large surface area to be in contact with the wine sample.
• Glass body
A glass body is easy to clean and staining resistant.
• Large LCD
An enhanced LCD displays the measurement reading, stability
indicator, low battery indicator, and calibration tags.
• Automatic calibration
The Foodcare Wine pH Tester is calibrated automatically
to one or two points. The calibration buffers are
automatically recognized and after calibration the
buffer values used are shown on the display.
• Stability indicator
An hourglass indicator is displayed on the LCD until a
stable reading is obtained. Once a reading stabilizes,
the indicator disappears and a reading can be taken.
• Automatic shut-off
The meter can be set to automatically turn off after 8
minutes or 60 minutes to conserve battery life.
• Probe diagnostic
During calibration the meter will display error (Err) message
as an indicator that the probe needs to be cleaned.
• Long battery life
The Foodcare Wine pH Tester has an exceptional battery
life of approximately 1000 hours. When the battery power
is running low, a low battery indicator is displayed.
