2. Remove protective cap by rotating while grasping and pulling up.
3. Rinse sensor well and cell cup 3 times with sample to be
measured. Shake out each sample to remove any residual liquid.
4. Refill both sensor well and cell cup with sample.
5. Press .
6. Take reading.
7. Press ms to store reading in memory, if desired.
imPOrtant: After use, fill pH/ORP sensor well with Myron L
pH Sensor Storage Solution and replace protective cap. If
Myron L pH Sensor Storage Solution is unavailable, you can
use a strong KCl solution, a pH 4 buffer, or a saturated solution
of table salt and tap water (ref. Cleaning Sensors, 2. pH/ORP,
pg. 50). Do not allow pH/ORP sensor to dry out.
3. Measuring Free Chlorine
1. Ensure the 9P is in free chlorine mode (ref. ORP Mode
Selection, pg. 21).
2. Remove protective cap by rotating while grasping and pulling up.
3. Thoroughly flush the sensor well and cell cup with a steady
stream of the solution you intend to measure by allowing the
solution to flow into and out of the sensor well and cell cup for
at least 10 seconds.
4. Refill both sensor well and cell cup with sample.
5. Press .
6. Take reading. Annunciators alert you when the concentration is
outside the specified measurement range. “-Or-” (over range)
will display when the concentration is over the range limit (>
10.00 ppm).
7. Press ms to store reading in memory if desired.
imPOrtant: After use, fill pH/ORP sensor well with Myron L
pH Sensor Storage Solution and replace protective cap. If
Myron L pH Sensor Storage Solution is unavailable, you can
use a strong KCl solution, a pH 4 buffer, or a saturated solution
of table salt and tap water (ref. Cleaning Sensors, 2. pH/ORP,
pg. 50). Do not allow pH/ORP sensor to dry out.
vi. sOlUtiOn selectiOn
A. Why Solution Selection is Available
Conductivity, resistivity, and TDS require temperature correction to
25°C values (ref. Standardized to 25°C, pg. 56). Selection determines
the temperature correction of conductivity and calculation of TDS from
