GENERAL DESCRIPTION
HI9819X is a portable logging multiparameter system (instrument, probe) that monitors up to 14
different water quality parameters (7 measured, 7 calculated).
The microprocessor‑based intelligent multisensor probes allows measurement of many water quality
parameters such as pH, ORP, dissolved oxygen, conductivity and temperature with data logging. The
system is easy to setup and easy to use.
The HI9819X features a graphic, backlit display that automatically sizes the digits to fit the screen
with on‑screen graphing capability. Each parameter is fully configurable.
HI9819X was designed to withstand harsh environments and is the ideal solution for field measure‑
ments of lakes, rivers and sea.
The meter meets IP67 standards (30 minute immersion at a depth of 1 m) and the multisensor probe
meets IP68 standards (continuous immersion in water).
Main features of the HI9819X systems:
• Rugged meter and probe
• Easy to use
• Measure up to 14 parameters and display of up to 12 parameters
• Waterproof protection (IP67 for the meter and IP68 for the probe)
• Graphic LCD with backlight
• Built‑in barometer for D.O. concentration compensation (HI98194, HI98196 only)
• Quick calibration feature
• Measurement check to eliminate any erroneous readings
• Auto recognition of probe and sensors
• Log‑on‑demand and automatic logging (up to 45,000 samples) on meter for all parameters
• Graphical display of logged data
• USB interface for PC communication
• Auto‑ranging for EC readings (HI98194, HI98195 only)
• Good Laboratory Practice feature, the last 5 calibrations are automatically stored
• Field‑replaceable sensors with color coded caps

Chapter 2 - QUICK START
• Sensor O‑Rings must be lubricated with the supplied grease prior to installation.
• HI769819X probes have 2 or 3 sensor connectors sockets identified with color‑coded triangles:
• Connector 1 (red): For either pH/ORP, pH sensor
• Connector 2 (white): For dissolved oxygen sensor (HI98194, HI98196 only)
• Connector 3 (blue): For EC sensor (HI98194, HI98195 only)
• Position the connector key towards the center of the probe, make sure the connector is seated
correctly (the sensor will no longer move freely) before tightening the locking threads.
• To protect the sensors, screw the protective shield onto the probe body.
• With the meter off, connect the probe to the instrument input on the top of the meter. Align the
pins and key then push the plug into the socket and tighten the thread.
• Turn the meter on by pressing the On/Off key. The meter will automatically recognize the probe
and the installed sensors and identify them on the probe status screen.
• Press Measure to view the measurement screen.

BASIC OPERATION
The main operating modes for HI9819X are measurement, logging and setup.
The measurement screen can be configured to display a single measurement or up to 12 simultane‑
ous measurements by using the numbers 1‑7 on the keypad. Use the / keys to scroll through
the measurements not being displayed. See page 24 for more details.
The measurement units will blink if the system has not been calibrated and the measurement number
will blink when the reading is out of range.
Press Log to display the logging menu. You can either log a single sample on the meter or start an
interval log on the meter. See Chapter 10 for more details.
Press Menu to enter setup mode. You can configure which parameters you want to measure, calibrate
the sensors, change system settings and view the meter and probe status.

SENSOR DESCRIPTIONS
HI7698194‑0 Combination pH sensor features a glass pH sensitive
bulb and a silver/silver chloride double junction reference with gelled
electrolyte.
HI7698194‑1 Combination pH/ORP sensor features a glass sensitive
bulb for pH readings, a platinum sensor for redox measurements and
a silver/silver chloride double junction reference with gelled electrolyte.
Note: See page 18 for pH preparation.
See page 18 for ORP activation.
HI7698194‑2 Galvanic dissolved oxygen (D.O.) sensor. The thin gas
permeable membrane isolates the sensor elements from the testing
solution but allows oxygen to pass through. The oxygen that passes
through the membrane is reduced at the cathode and causes a current,
from which the oxygen concentration is determined. The D.O. sensor
conforms to Standard Methods 4500‑AG, EPA 360.1.
Note: The D.O. sensor needs to be activated before installation.
See page 18 for details.
HI7698194‑3 four ring‑electrode conductivity (EC/TDS/Resistivity/Sa‑
linity) sensor. The sensor is immune to polarization or surface coatings.

SENSOR PREPARATION / ACTIVATION
pH Preparation
Remove the shipping cap from the pH sensor. If the shipping cap does not contain any liquid, pour
HI70300 into shipping cap, place it back on the sensor and soak for at least 1/2 hour before use. If
HI70300 is not available, pH 4.01 buffer may be substituted.
ORP Activation
For improved redox measurements, the surface of the sensor must be clean and smooth. A
pretreatment procedure should be performed to ensure quick response.
The pretreatment of the sensor is determined by the pH and the ORP potential values of the sample.
Use the table below to determine the treatment required.
First locate the typical sample pH. If the corresponding ORP value (mV) is higher than the values in
the table below, an oxidizing pretreatment is necessary. If the value is lower, a reducing pretreatment
is necessary.
pH mV pH mV pH mV pH mV pH mV
0 990 1 920 2 860 3 800 4 740
5 680 6 640 7 580 8 520 9 460
10 400 11 340 12 280 13 220 14 160
For reducing pretreatment: immerse the electrode for at least five minutes in HI7091.
For oxidizing pretreatment: immerse the electrode for at least five minutes in HI7092.
D.O. Sensor Activation
The D.O. probe is shipped dry. To prepare the sensor for use:
• Remove the black & red plastic cap. This cap is used for shipping purposes only and can be thrown
away.
• Insert the supplied O‑Ring in to the membrane cap.
• Rinse the membrane with some electrolyte solution. Refill with clean electrolyte.
Gently tap the membrane cap to dislodge air bubbles. To avoid damaging the membrane, do not
touch it with your fingers or directly tap the membrane.
• With the sensor facing down screw the membrane cap counterclockwise to the end of the threads.
Some electrolyte will overflow.
• Rinse outside of sensor with deionized water.
• Invert sensor and inspect. There should be no bubbles or debris between the membrane and
sensor body.

19
EC Sensor Preparation
The EC sensor does not need to be soaked or hydrated before use. Use the small brush included in the
probe maintenance kit to clean and loosen any debris before using.
SENSOR INSTALLATION
The HI7698194 can support three different sensors:
Connector 1: pH, pH/ORP
Connector 2: D.O.
Connector 3: EC.
To make installation easier, the sensors have color‑coded caps and the sockets are identified with
colored triangles, corresponding to the colors of the sensors (pH ‑ red; EC ‑ blue; D.O. ‑ white).
