Introduction
Thank you for purchasing the Thermo Scientific™Eutech™
DO 1730 dissolved oxygen bench meter. The Eutech 1700
series meters are designed to provide the important
functions needed for routine measurements with simplified,
convenient, easy-to-use functionality.
The Eutech DO 1730 dissolved oxygen meters are capable
of measuring dissolved oxygen as % saturation or
concentration in mg/L or ppm simultaneously with
temperature. These meters offer a large, backlit display for
clear viewing with small footprint to conserve laboratory
bench space.
Ensure important data is preserved with a 500-point data
log with date/time stamp that can also be exported to a
printer or computer using the meter communication port.
All Eutech DO 1730 dissolved oxygen meters include a
meter-attached electrode holder and universal 100-240V
power adapter with wall plugs for US/Japan, Euro,
UK/Singapore, Australia/New Zealand and China.
Additional meter accessories can be viewed at
www.thermofisher.com/electrochemistry.
1.1 Intended Use
1.1.1 Intended Use
This device is a bench laboratory meter intended for use in
a typical, indoor, controlled, laboratory environment. This
device should only be used for analytical testing in
accordance with these instructions.
1.1.2 Non-Intended Use
This device is not a Medical Device. It is not intended to be
used to diagnose, treat, cure, or prevent disease.

will invalidate the warranty. For additional
information, contact Technical Support at
[e-mail]
or (65) 6778 6876.
1.1.4 Power Connection
See the Universal Power Supply Assembly section for
complete instructions on assembling and installing the
included meter power supply.
Note: Position the meter so the operator
can access the power connection and
unplug the power adapter in the event of
a fault so the hazard of electrocution can
be removed.
1.2 Cleaning Instructions
(Meter Only)
Wipe the exterior surfaces (except the display panel) using
a lint free cloth dampened in clean water.
Wipe the display panel with a clean microfiber cloth, taking
care to wipe lightly to avoid scratching the meter display.
The meter keypad can also be cleaned using a clean
microfiber cloth dampened with IPA (isopropyl alcohol) for
disinfection purposes.

Getting Started
2.1 Electrode Holder
Installation
The meter-attached electrode holder (Catalog Number
EB1700ARM) can be installed on either side of the meter.
Unpack the base plate and stand with electrode
holder from the meter box.
Turn the meter over, with the meter display facing
down, on a clean dry surface.
Identify the side of the meter that the holder will be
installed on and remove the screw between the
circles on that side of the meter.
Align the base plate of the holder with the circles on
the meter.
Replace the screw from step 3 to attach the base
plate to the meter.
Turn the meter over, with meter display facing up.
Insert the stand with electrode holder into the metal
post on the base plate.
Place the electrodes into the electrode holder. The
recommended electrode diameter for each slot is
shown on the holder.

2.2 Universal Power
Supply Assembly
A universal power adapter (Catalog Number EB1700PWR)
with US/Japan, Euro, UK/Singapore, Australia/New
Zealand and China wall plug plates is included with the
meter. This universal power adapter is specifically for use
with this meter. Use of other power adapters can damage
the meter and will void the warranty.
Note: The power adapter plug has two prongs that allow
the power adapter to be locked onto the meter. These two
prongs must be properly aligned when connecting it to
ensure it is fully connected and locked onto the meter.
Unpack the power supply provided with the meter.
Select the appropriate wall plug plate for the power
outlet that will be used.
Slide the appropriate wall plug plate into the groove
on the back of the power adapter.
Connect the assembled power adapter to the meter
input.
Locate the two slots on the meter power input.
Align the two tabs on the power adapter connector
with the two slots on the meter power input.
Insert the power adapter connector into the meter
power input and twist clockwise to lock the
connection.
Connect the assembled power adapter to a power
outlet.
You are now ready to turn on the meter.
CAUTION: Use of a surge protector or
uninterrupted power supply (UPS) is
recommended, as an unintended power
surge of electricity to the meter may
damage the meter and void the warranty.
