Hanna Instruments HI900601,HI900602,HI900603,HI900604 Owner Manual
Dear Customer,
Thank you for choosing a Hanna Instruments product.
Please read this instruction manual carefully before using
the probe. For more information about Hanna Instruments
and our products, visit www.hannainst.com or e-mail us at
For technical support, contact your local Hanna Instruments
Office or e-mail us at tech@hannainst.com.
Preliminary Examination
Remove the photometric probe from the packing and examine it
carefully. For further assistance, please contact your local Hanna
Instruments Office or email us at tech@hannainst.com.
Each HI900600 series photometric probe is delivered in a plastic
case and is supplied with:
• Trimmer tool
• Quality certificate
• Instruction manual
mV range
10 to 1100 mV
Light source

LED pulsed at 1 kHz
Light detector
Silicon photocell
Sample temperature
0 to 75 °C (32 to 167 °F)

Body material
• The HI900600 family of photometric probes can be connected
to the HI932, HI931, HI902C, HI901C and HI901W titrators
by plugging the BNC connector to the pH/ORP/ISE port and
PS/2 connector to the keyboard port.

• For use with the HI921 and HI922 Autosamplers, install the
electrode and dispensing tubes identical as the HI93x electrode
holder. The cable of the electrode is long enough to reach the
BNC and PS/2 connectors of the HI90x or HI93x Titrator.
• The dispensing tip must be slightly submerged into the sample
during use, this prevents the titrant pump from injecting
bubbles into the sample. If necessary trim the blue protective
tubing to allow the dispensing tip to be submerged into the

Note: Save all packing material until you are sure that the
probe works correctly. Return items must be returned in
the original packing material with the supplied accessories.

General Description & Intended Use
• Reflective measurement allows for high color sensitivity in a
compact design.
• Drift from changes in temperature is automatically compensated.
• Glass body offers excellent chemical resistance.
• LED brightness trimmer is provided in the head of the probe to
adjust the LED intensity.

• The photometric probe can be installed in two locations on the
HI93x electrode holder (one location on the HI90x). Both of
these place the probe as far downstream from the clockwisespinning titrant as possible. See the images below for the
electrode and titrant tube position.
120 mm
The HI900600 series are photometric probes used with a
potentiometric titration for equivalence end point detection of
colorimetric reactions. These probes are available in 4 different
wavelengths from 470 nm to 625 nm and have a universal BNC
connector that is used as a potentiometric input on Hanna titrators
and autosamplers.
The optimal wavelength depends on the indicator for the method - a
wavelength should be selected at which the indicator causes a large
mV change between its reacted and unreacted forms.
Recommended Immersion

General Operations
Care & Maintenance
• To avoid the generation of air bubbles, the stir speed should
not exceed 800 RPM.
• Reagent addition feature on the autosampler can generate air
bubbles, it is recommended to add the reagents with the probe
above the sample beaker. To do this set the head height to 80
to 100 mm for reagent addition operations.
• For best reproducibility, use linear dosing setting. If dynamic
dosing is used a narrow range, such as 0.040 to 0.100 mL is
The HI900600 photometric probes are fragile and can crack easily
if mishandled. Handle the probe by the green top only and do not
allow the stirrer assembly to hit it.
The probe can be cleaned after each use with a gentle stream of
deionized or distilled water. If necessary, soak the probe in HI7061
Electrode cleaning solution for general use for 20 minutes, rinse
throughly with distilled or deionized water before use.
All Hanna Instruments conform to the CE European Directives.
LED Calibration
The LED will slowly dim over time, this is normal. LED adjustment
is not critical for the measurement but it is recommended to follow
this procedure before the first use and once per week.
• Connect the probe to the titrator or autosampler.
• Place the probe in deionized or distilled water. Swirl gently to
remove any air bubbles from the optical cell.
• On the home screen or in mV mode, note the mV reading.
• Remove the cap covering the hole marked “CAL”.
• Using the supplied trimmer tool slowly turn the screw clockwise
until the screen shows 1000 mV.
Caution: If the trimmer screw is turned too far in the positive
(clockwise) direction, it is possible that the probe electronics
can no longer amplify the mV signal. This will occur at some
point above 1200 mV. If this occurs, it will take several
turns of the screw in the negative (counter-clockwise)
direction before a change in the mV signal will occur.
• Replace the cap when procedure is complete.
