Range Iron LR 0.00 to 1.60 mg/L
pH 6.5 to 8.5
Resolution 0.1 pH
0.01 mg/L Iron LR
Accuracy Iron LR ±0.01 mg/L ±8% of reading @ 25°C
pH ±0.1 pH @ 25°C
Typical EMC Dev. ±0.01 mg/L Iron LR
±0.1 pH

Method For Iron LR: Adaptation of the TPTZ method. The reaction
between iron and the reagent causes a violet tint in the
sample.
For pH: Phenol red method. The reaction with reagents
causes a red tint in the sample.
Environment 0 to 50°C (32 to 122°F);
max 95% RH non-condensing
Battery Type 1 x 9 volt
Auto-Shut off After 10' of non-use in measurement mode;
after 1 hour of non-use in calibration mode;
with last reading reminder.
Dimensions 192 x 104 x 69 mm (7.6 x 4.1 x 2.7”)
Weight 360 g (12.7 oz.).
1. RANGE/GLP/ key: press to change the paramter, press and hold
for three seconds to enter GLP mode. In calibration mode press to edit
the date and time.
2. CAL CHECK key: press to perform the validation of the meter, or
press and hold for three seconds to enter calibration mode.
3. ZERO/CFM key: press to zero the meter prior to measurement, to
confirm edited values or to confirm factory calibration restore.
4. READ/ /TIMER key: In measurement mode, press to make a
measurement, or press and hold for three seconds to start a pre-
programmed countdown prior to measurement. In
GLP mode press to
view the next screen.

DISPLAY ELEMENTS DESCRIPTION:
Functional description:
1. The measuring scheme (lamp, cuvette, detector), appears during
different phases of zero or reading measurement
2. Error messages and warnings
3. The battery icon indicates the change state level of the battery
4. The hourglass appears when an internal check is in progress
5. Status messages
6. The chronometer appears when the reaction timer is running
7. The month, day and date icons appear when a date is displayed
8. Four digit main display
9. Measuring units
10. Four digit secondary display
Light High: There is too much light to perform
a measurement. Please check the preparation of
the zero cuvette.
Light Low: There is not enough light to perform
a measurement. Please check the preparation of
the zero cuvette.
No Light: The instrument cannot adjust the
light level. Please check that the sample does
not contain any debris.
Errors and warnings:
ON ZERO READING:
ON SAMPLE READING:
DURING CALIBRATION PROCEDURE:
OTHER ERRORS AND WARNINGS:
Cap error: Appears when external light enters
in the analysis cell. Assure that the cuvette cap
is present.
Cooling lamp: The instrument waits for the
lamp to cool down.
Battery low: The battery must be replaced
soon.
Dead battery:
This indicates that the battery
is dead and must be replaced. Once this
indication is displayed, normal operation of the
instrument will be interrupted. Change the
battery and restart the meter.
Standard Low: The standard reading is less
than expected.
Standard High: The standard reading is higher
than expected.
Inverted cuvettes: The sample and the zero
cuvette are inverted.
Zero: A zero reading was not taken. Follow the
instructions of the measurement procedure for
zeroing the meter.
Under range: A blinking “0.00” indicates that
the sample absorbs less light than the zero
reference. Check the procedure and make sure
you use the same cuvette for reference (zero)
and measurement.
Over Range:
A flashing value of the maximum
concentration indicates an over range condition.
The concentration of the sample is beyond the
programmed range: dilute the sample and
re-run the test.
1• Turn the meter on by pressing ON/OFF.
2• When the beeper sounds briefly and the
LCD displays dashes and “P1” (Iron LR) or
“P2” (pH) the meter is ready. The code
that appears on the secondary display is
the one of the last selected parameter. If
necessary, press RANGE/GLP/ to
change parameter. The blinking “ZERO”
indicates that the instrument needs to
be zeroed first.
3• For Iron LR: Fill one graduated mixing
cylinder up to the 25 mL mark with
deionized water. Add the content of one
packet of HI 93746-0 reagent, close the
cylinder and shake well for 30 seconds.
This is the blank. Fill a cuvette with 10
mL of the blank up to the mark and
replace the cap.
For pH: fill the cuvette with 10 mL of
unreacted sample, up to the mark, and
replace the cap.
4• Place the cuvette into the holder and
ensure that the notch on the cap is
positioned securely into the groove.
5• Press ZERO/CFM and the lamp, cuvette
and detector icons will appear on the
display, depending on the measurement
phase.
6• After a few seconds the display will show
“-0.0-” . The meter is now zeroed and
ready for measurement.
7• Remove the cuvette.
8• Iron LR: Fill one graduated mixing cylinder
up to the 25 mL mark with the sample.
Add the content of one packet of HI 93746-
0
reagent, close the cylinder and shake
well for 30 seconds. Fill a cuvette with
10 mL of the reacted sample up to the
mark and replace the cap.
pH: fill the cuvette with 10 mL of unreacted
sample, up to the mark, add 5 drops of
HI 93710-0
, replace the cap and invert
several times to mix.
9• Replace the cuvette into the holder and
ensure that the notch on the cap is
positioned securely into the groove.
10•Press and hold READ/ /TIMER for three
seconds . The display will show the
countdown prior to measurement. The
beeper is playing a beep at the end of
countdown period.
Dead battery: This indicates that the battery
is dead and must be replaced. Once this
indication is displayed, normal operation of the
instrument will be interrupted. Change the
battery and restart the meter.
