General Description & Intended Use

The HI981031 Beer pH Tester is designed to measure the pH during the brewing process. It features a single button operation system and is easy to use. It has a compact and waterproof casing and automatic pH calibration at one or two points. All readings are automatically compensated for temperature variations with a built-in temperature sensor. The flat tip of the pH electrode allows easy cleaning of the pH sensing surface as solids from mash and cooled wart collect on the surface. The pH electrode is equipped with extractable cloth junction. Pulling out a small portion of the junction increases response time and extends electrode life.

Probe Features

Flat Glass Tip
The flat tip provides optimal surface contact and allows easy cleaning of the sensing surface as solids collect on the surface. The pH electrode is designed to measure the pH of samples with temperature up to 80°C (176°F).

Extractable Cloth Junction
Allows for clearing any clogging from solids that would result in slow response and unstable readings. Pull 3 mm (1/8 ") to expose a fresh new surface of the junction resulting in fast response time and reading stability.

Titanium Body
Rugged and resilient, the titanium body of the probe works as an electronic shield protecting against interferences from electrical noise or humidity. The titanium body is virtually unbreakable, offering protection from accidental breakage.

Functional Description & LCD Display

Preparation

Remove the protective cap. Do not be alarmed if salt deposits are present. Rinse the probe with water and blot dry.
If the glass and / or junction are dry, soak the electrode (bottom 4 cm / 1.5") in storage solution for a minimum of 30 minutes. Rinse with water and blot dry.
Calibrate the electrode before using. For best results is recommended to recalibrate periodically.

Storage

To ensure a quick response, the glass tip and junction should be kept moist.
Replace the protective cap with a few drops of storage solution when not in use. Do not store the electrode in distilled or deionized water.

Operation

Press the ON/OFF button to turn the tester on. The tester displays all LCD segments for a few seconds. The tester will enter measurement mode, the current reading and calibrated buffers will be shown.
Operation

Calibration

From measurement mode, press and hold the ON/OFF button until "CAL" is displayed.
Calibration

For one or two-point calibration using pH 7.01 buffer solution, follow A procedure A.
For one-point calibration using pH 4.01 buffer solution, follow B procedure B.
Note: It is recommended to calibrate the electrode with buffers at the temperature it will be used at.

One or Two-Point Calibration with pH 7.01

When "7.01" is displayed, place the tip of the electrode in pH 7.01 buffer. When the reading is stable, the stability icon will disappear. When "4.01" is displayed, follow the procedure to the right for a one or two-point calibration.
One-Point

Press the ON/OFF button to save the one-point calibration.

"Sto" will be displayed when the calibration is saved.

The tester will return to measurement mode and the calibration tag will be displayed.

Two-Point

Place the tip of the electrode in pH 4.01 buffer. The buffer is automatically recognized, the stability indicator will blink.

Wait until the measurement is stable and the stability indicator disappears. "Sto" will be displayed when the calibration is saved.

The tester will return to measurement mode and the calibration tags will be displayed.
One-Point Calibration with pH 4.01

When "7.01" is displayed, place the tip of the electrode in pH 4.01 buffer. The buffer value will be recognized automatically and "4.01" will be displayed.

When the reading is stable, the stability indicator will disappear."Sto" will be displayed when the calibration is saved.

The tester will return to measurement mode and the calibration tag will be displayed.

Auto-Off

From measurement mode, press and hold the ON/OFF button. The LCD will show "OFF", "CAL" followed by "d08" (default setting, 8 minutes). Release the ON/OFF button. A single press on the ON/OFF button will change the auto-off timer to "d60" (60 minutes). To disable the auto-off feature press the ON/OFF button again, LCD will show "d--". Press and hold to exit.

Clear Calibration

To clear the user calibration and restore the tester to factory default. From calibration mode, press and hold the ON/OFF button, the LCD will show "CLr".
Clear Calibration

"Err" Message

In calibration mode, if the probe is in the correct buffer solution and the "Err" message is displayed, the probe should be cleaned. Soak the probe in cleaning solution for 20 minutes. Rinse with water and hydrate electrode in storage solution for a minimum of 30 minutes before calibrating.

Battery Indicator

When the battery level is low, the tag on the LCD will blink. When the battery is depleted the "Erb" message is displayed and the tester is powered off.

Care & Maintenance

Please read the information below, to ensure the highest possible accuracy:

Fresh buffer should be used for each calibration, once the sachets are opened the buffer value can change over time.
For improved accuracy a two-point calibration is recommended.
If the electrode is slow or sluggish, soak it in cleaning solution for 20 minutes. Rinse with water and hydrate the electrode in storage solution for a minimum of 30 minutes before calibrating.
If measurements are taken successively, rinse the probe thoroughly in distilled or deionized water to eliminate cross-contamination.
When not in use, add a few drops of storage solution to the protective cap to keep the glass tip and the junction hydrated. If storage solution it not available, pH 4.01 or pH 7.01 buffer can be used. Never store the probe in distilled or deionized water.
The probe should be cleaned after each use with a soft tissue to eliminate all impurities.
Note: Never immerse the tester over the maximum immersion level.

Battery Replacement

To change the CR2032 lithium-ion battery, turn the battery cover, located on the back of the tester, counterclockwise to unlock. Remove cover and replace the battery with positive (+) side facing out.
Battery Replacement
Note: Only use the battery type specified in the manual. Old batteries should be disposed in accordance with local regulations.
