The HI98198 opdo™meter is a rugged, portable dedicated dissolved oxygen (DO) meter designed
for fresh and saltwater measurements of dissolved oxygen. This professional, waterproof meter com‑
plies with IP67 standards and measures DO, barometric pressure, and temperature. The HI98198 is
supplied with a HI764113 digital optical dissolved oxygen probe in a custom thermoformed durable
carrying case with accessories. It is compact and ergonomically designed to provide ready access to
the materials required for routine sampling.
The HI98198 opdo™meter is only compatible with the Hanna digital dissolved oxygen probe
(HI764113).
Concentration measurements are automatically compensated for barometric pressure, temperature
and salinity. Barometric pressure and temperature are automatically measured and compensated.
Salinity is automatically compensated by setting manually the salinity concentration of the water
being measured. The meter also has a built in application to measure and calculate BOD (Biological
Oxygen Demand), OUR (Oxygen uptake rate), and SOUR (Specific Oxygen Update Rate).
Other features include:
• Text messages on the graphic LCD display to warn and guide the user.
• Back lighted display.
• One or two points calibration at 0 or/and 100% saturation (with auto recognition).
• A single point manual calibration in mg/L or % saturation using a reference method for calibration
value.
• A dedicated HELP key for assistance anytime.
• A user selectable “Calibration due” warning.
• A dedicated GLP key that includes at last 5 calibrations with time, date, calibration points as well
as barometric pressure, temperature and salinity setting.
• AutoEnd freezes the next stable measurement value on the display.
• Log on demand with 4000 records capability.
• USB‑C port for easy data transfer to memory stick, PC or other compatible device.

THEORY OF OPERATION
THEORY OF OPERATION
The Hanna HI764113 optical DO sensing probe is based on the principle of fluorescence quenching.
The sensing method features an immobilized Pt based luminophore that is excited by the light of a
blue LED and emits a red light. Dissolved oxygen quenches this excitation. When there is no oxygen
present, the lifetime of the signal is the greatest; as oxygen hits the sensing surface, the lifetime
becomes shorter. The intensity and lifetime are inversely proportional to the amount of oxygen present;
as oxygen interacts with the luminophore it reduces the intensity and lifetime of the luminescence. The
lifetime of the luminescence is measured by a photodetector, and is used to calculate the dissolved
oxygen concentration. This is in turn reported by the meter as a % saturation or mg/L reading of
Dissolved Oxygen.
The major components of the probe include a blue LED for excitation, a red LED that is used as a reference
light, and a photodetector. The Smart Cap™ is locked in place on the optical probe and includes the
immobilized O2sensitive luminophore with rugged insoluble black oxygen permeable protective layer.
Over time, the sensor’s optical components can age but are compensated for by using the reference
signal to compensate the measuring path. As a result, the sensor provides accurate DO measurements
over long periods of time without the need for frequent calibration.

GETTING STARTED
1. Remove the HI764113 from the carrying case. Remove stainless steel guard
from probe body if it was installed. Use care not to leave fingerprints on the
optical window.
2. Sparingly lubricate the O‑ring with a thin film of silicone grease. Use care
to prevent grease from contacting the optical window.
3. Remove the HI764113‑1 optical cap from the container. Align the notched
cutout arrow on the Smart Cap™ with the matching guide on the probe
body.
4. Slide and press the Smart Cap™ onto the HI764113 body until
the cap snaps in place. Once the cap is installed, it should not
be removed unless a new cap is required.
5. Connect the HI764113 probe to the HI98198 meter by plugging
the DIN connector to the socket located on the top of the meter.
6. Power the meter to initiate the cap timer.
Note: Turn off the meter before connecting or disconnecting
the probe.
INITIAL PREPARATION
Install the supplied batteries into the meter. See Batteries Replacement for details, page 52.
To prepare the meter for field measurements close the USB communication socket with the attached
stopper.
Turn the meter ON by pressing ON/OFF key.
At start‑up the meter will show the Hanna Instruments logo for a few seconds, followed by the
percentage indication of the remaining battery life.
Before connecting the probe for the first time, press SETUP and using / arrows navigate to
Date/Time. Press Modify and set the current date and time.
Note: Verify time and date are properly set on meter prior
to probe initialization.

GETTING STARTED
“No Probe” message is displayed on meter if the probe connector is not plugged in properly.
The “No cap info detected. Install the cap and press Continue.“ message on the meter indicates
that the Smart Cap™ is missing or not properly installed on the probe.
No conditioning period is required when using a HI764113 DO probe.
Store the HI764113 probe in the HI98198 carrying case when not in use.
For frequent use and short term storage it is recommended to remove the stainless steel guard and
replace with the storage vessel that has a small amount of deionized water. The probe can also be
stored with the stainless steel guard on in a beaker containing deionized water.
For longer term storage, remove the stainless steel guard and replace with the storage vessel.
A probe info screen will be displayed momentarily before defaulting to the measurement screen:

PARAMETER SCREENS
Log Separator
Log separator or CSV file separator is a special character used to separate columns in the CSV log
file. There are two options available: Comma (,) or Semicolon (;). The field separator depends upon
regional preferences.
Press the function key to modify the CSV file separator.
SETUP
Salinity
Dissolved oxygen solubility decreases if water contains salts. This parameter is used to compensate
concentration measurements (mg/L) made in brackish or sea water samples. The salinity is expressed in
PSU scale and is manually entered by the user. The DO concentration will be automatically compensated
to improve the accuracy during calibration and measurement. Enter the salinity value to be close to
the known salt level of the sample. Seawater typically has a salinity of 35 and the oxygen solubility
is 18% less as compared to fresh water at 25 °C. By entering the approximate salinity value, the
calibration and subsequent concentration measurement will be compensated to display the correct
oxygen concentration. An 18% error would result if the salinity value is not entered.
Highlight Salinity.
Press Modify.
Use / keys to change the salinity value. Press Accept to confirm or ESC to exit without saving.

SETUP
Calibration Timeout
The HI764113 dissolved oxygen probe utilizes optical technology which offers significant advantages
over polarographic or galvanic type dissolved oxygen probes. Some advantages include reduced
maintenance, simplified handling and infrequent calibrations. However if a user wishes to validate
or calibrate on a SOP schedule, a timer may be set as a reminder.
The Calibration time out parameter can be set from 10 to 70 days or can be disabled.
The meter is provided with a real time clock (RTC) and is used to monitor the time elapsed since the
last DO calibration.
The calibration timer is reset every time the meter is calibrated and the “CAL DUE” status is triggered
when the meter detects a calibration time out. The “CAL DUE” tags will start blinking to warn the
user that the meter should be recalibrated.
If the calibration timeout is changed (e.g. to 20 days), then the timer will be immediately reset.
Notes:
- Before the DO calibration is cleared (default values loaded) the display always shows the
“CAL DUE”.
- Before an abnormal condition in the RTC is detected, the meter forces the “CAL DUE”
status.
- After a user temperature or pressure calibration is made (or cleared), the “CAL DUE”
message will be activated.
