KIT OVERVIEW
GETTING STARTED
If first-time use, or if the meter hasn’t been used for a long time, pour about 5mL of
3M KCL storage solution into the probe cap (about 1/5 of the cap) and soak probe
for a minimum of 15 minutes. Rinse the probe and place into the storage solution.
When not in use, store the pH probe in a pH 4.00 buffer solution. Use enough to
completely immerse the pH glass bulb. If the probe was stored dry, soak in pH
4.00 buffer for at least 4 hours to restore the probe’s sensitivity. Soak the probe for
12 hours to achieve maximum accuracy.
If the unit is stored dry, the probe will not be permanently damaged, but will
temporarily lose its stability. Stability can be restored by soaking the probe in the
supplied 3M KCl storage solution (one 10ml bottle of storage solution comes with
the kit). If this solution becomes cloudy replace it as soon as possible.
* DO NOT use a different brand of storage solution. Using a different chemical
may, potentially, cause the probe to function poorly (also void the warranty).

FOR BEST ACCURACY
Buffers for calibration should be based on the measurement range.
Follow the calibration procedure properly.
Be sure to remove air bubbles from pH glass bulb for accurate measurements.
Store the meter and all test materials out of direct sunlight, heat, and away from
chemical storage areas.
Minimize exposure of meter and calibration solutions to heat above 100°F (38°C).
Dry the outside of the meter when testing is complete or before storage of the meter.
Pour pH 4.0 buffer solution up to the "FILL" line of the storage cap. Always store
the pH probe in clean 4.00 pH buffer solution.
Do not store the pH probe in a distilled or deionized water. This will cause
permanent damage to the probe.
Always fill the sample collection bottle with enough sample to completely
immerse the probe.
Rinse pH probe properly before putting in storage solution.
The meter has an automatic shut-off after 8 minutes of idle time.
This meter performs best in pool and typical tap water and does not give
reliable readings in distilled or deionized water.
Remove batteries when meter is not used for more than a month (Warranty Requirement).
Do not touch or rub the pH glass bulb.
To avoid cross-contamination, rinse the probe properly with clean water in
between measurements.
To clean the ORP sensor, dip the probe into 0.1 mol/L dilute hydrochloric
acid for 30 minutes; clean the platinum surface with dishwashing liquid; or use
plain white toothpaste to gently clean the platinum surface.Then, rinse with
clean water and soak for 6 hours in the KCl storage solution.

1The 1st point calibration must be in pH 7.00 buffer. Perform the
2nd point calibration (pH 4.00) immediately after the 1st point.
Do NOT turn off the meter before you conduct the 2nd point
calibration. If the meter is turned off after the 1st point calibration
the calibration process must be repeated. Calibrating directly in
pH 4.00 after turning the meter off and back on will cause Er1.
2If you find air bubbles in the pH glass bulb, shake the probe a few
times in an upward/downward motion to remove the bubbles. If
air bubbles are attached to the outside of the glass bulb, swirl the
probe in the solution to remove them. Air bubbles in the glass bulb
will cause unstable measurements.

PH CALIBRATION NOTES
• The meter will automatically recognize 5 types of pH buffer
solution (see USA/NIST series list below). Users can perform
1-point, 2-point (recommended), or 3-point calibration.
• Perform one-point
calibration (7.00 buffer) first before
proceeding to two-point and three-point calibration.
• Use pH buffers for two-point and three-point calibration as in the
table below:
• To maintain the accuracy of the pH buffer standards, replace them
after five (5) uses. To prevent contamination, NEVER pour used pH
Buffer solutions back into the original pH Buffer solution bottles.
• This pH probe was not designed to give accurate readings for
distilled or deionized water There are not enough ions present in
these waters for accurate detection.
• When testing purified water like spring water or drinking water, it
will take longer for the readings to stabilize (typically 3-5 minutes)
because there are low levels of ions for the sensor to detect.
• DO NOT store the pH probe in distilled water. This will cause
permanent damage to the probe.
• pH Buffers for calibration should be selected based on
the measurement. 2-point (7.00 and 4.00) Calibration is
recommended for most applications.
• Avoid cross-contaminating the pH buffers. Rinse the pH probe
and blot excess water after each measurement.
• Do not rub or touch the pH glass bulb!
Important Operation Note: the eXact pH
+
Smart Meter was especially
engineered/designed for the nontechnical service person who requires
a quick and accurate (within ±0.05) on-site pH measurement. The test
methodology, if followed carefully, is this:
Perform 2-point calibration weekly and store pH probe in 4.00 pH Buffer
between measurements. During the week of use, each time you power ON
eXact pH
+
meter, the pH should display between 3.97 and 4.03. This verifies
the meter is still maintaining calibration. When display is <3.97 or >4.03.
discard the solution and pour a fresh pH 4.0 buffer solution and check
display again. Remove Probe Storage Cap and set aside with pH 4.00
Buffer solution. Rinse the pH probe with clean water, then proceed to pH
measurement. More frequent calibrations may be needed if testing solutions
in extreme temperatures or substantial changes in pH such as from 10 to 4.

• The TDS and Salinity measurements are calculated from the
conductivity measurements by using conversion factors.
•
The meter can recognize 84μS, 1413 μS/cm and 12.88 mS/cm
conductivity calibration solutions. The user can conduct 1 to 3 points
calibration. Refer to the table below. Usually calibrating the tester with
1413 μS/cm conductivity buffer solution alone shall meet the testing
requirement. However, we recommend choosing a calibration solution
close to the expected conductivity of your sample.

Calibration
Standards Measuring Range
84μS/cm 0 - 200 μS/cm
1413 μS/cm 200 - 1999 μS/cm
12.88 mS/cm 2 - 20 mS/cm
• The tester has been calibrated before leaving the factory. For best
accuracy we recommend testing a conductivity buffer solution
before use. If the error is large, then calibration is needed.
• To maintain the accuracy of conductivity calibration solutions, we
recommend replacing the solutions after 3 to 5 uses. To prevent
contamination, Do NOT pour used calibration solutions back into
the original bottles.
• Temperature compensation factor: The default setting of the
temperature compensation factor is 2.0%/°C. Users can adjust the
factor depending on the solution or experimental data (see table
below). Use parameter setting P4 to adjust the factor.
Solution Temperature
compensation factor
NaCl 2.12%/°C
5% NaOH 1.72%/°C
Dilute ammonia 1.88%/°C
10% Hydrochloric acid 1.32%/°C
5% Sulfuric acid 0.96%/°C
• 1000 ppm = 1 ppt 1000 μS = 1 mS
• TDS and conductivity are linearly related; the conversion factor
ranges from 0.40-1.00. The factory default setting is 0.71. Salinity
and conductivity are also linearly related; the conversion factor
is 0.5. The tester only needs to be calibrated in Conductivity
mode. After calibration for conductivity, the meter can switch from
conductivity to TDS or salinity.
• Conversion Example: if conductivity measurement is 1000μS/
cm, then the default TDS measurement will be 710 ppm (under the
default 0.71 conversion factor), and the salinity will be 0.5 ppt.
• Avoid cross-contaminating the conductivity standard solutions.
Rinse the sensors and blot dry after every measurement.
