adjust the minerals in brewing water to improve
beer fl avor and yield. The Brewlab Plus
TM
also
includes a high quality, waterproof, digital pH
meter for measuring the resulting mash, wort,
and beer pH
.

SODIUM (by calculation)
Since water has a neutral charge, the total number of negatively charged
anions must equal the total number of positively charged cations. Six ions
typically make up 98% of the total ions so the sodium concentration can be
estimated by testing for the fi ve other ions.

Before First Use or After Storage
1. Hold meter by top battery compartment. Swiftly tap back of meter
downward into palm - not a hard surface - to move electrolyte into
electrode tip.
2. Remove cap. Soak electrode in pH 4.0 buffer or tap water for 10 minutes.
pH
Sample should be below 122 °F (50 °C). Let cool if necessary.
NOTE: The purpose of ATC in this meter is to maintain electrode calibration
across the capability range of 32-194 °F (0-90 °C). It is recommended that
wort samples be cooled to room temperature (68 °F/20 °C) before testing.
This allows better comparison of measurements at different temperatures
due to the natural change in wort pH due to changes in temperature, and
improves electrode life.
1. Remove cap. Press ON/OFF to turn meter on.
2. Dip sensor in sample water.
3. Record pH after reading becomes stable and display stops fl ashing.
4. Press MODE to hold reading and store reading in memory
5. Press ON/OFF to shut meter off.
6. Store in pH 4.0 buffer. Store upright.
Daily Calibration Procedure
1. Fill tube (0715) to 20 mL line with distilled water. Pour into small container.
Add pH 7.0 Mini Buffer Tablet (3984A). Stir until tablet disintegrates.
2. Remove cap. Press ON/OFF to turn the meter on.
3. Dip sensor in buffer.
4. Press CAL. END will be displayed and the circled 7 indicator will be
displayed.
5. Repeat Steps 1–4 with pH 4 Mini Buffer Tablet (3983A). Save pH 4 Buffer
to use as storage solution. Tester is calibrated.
Do Not allow pH sensor to dry out.
¬ Store Upright
¬ Before fi rst use, tap meter against
palm to move electrolyte to tip.
Maintenance
1. Rinse sensor with clean water immediately after each use.
2. Do not allow sensor to dry out. Store tester with cap on. Moisten sponge
in cap with
3. If surface contamination is visible or readings become erratic, wet disposable
towel with ethanol or isopropyl alcohol and gently rub surface of sensor
until no more residue is visible.
Notes:
1. White crystals may form around cap and should periodically be rinsed
off. These deposits could affect measurements at low conductivity.
2. Tester automatically shuts off after 8.5 minutes of non-use.
3. For testing samples at high pH, tester can be calibrated with pH 7.0 Mini
Buffer Tablets (3984A) and pH 10.0 Mini Buffer Tablets.
