Introduction

Thank you for purchasing the Thermo Scientific™Eutech™

EC 1720 conductivity 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 EC 1720 conductivity meters are capable of

measuring conductivity, salinity or total dissolved solids

(TDS) 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 EC 1720 conductivity meters include a meter-

attached electrode holder and universal 100-240V 50/60

Hz 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.

1.1.3 Safety

CAUTION: This symbol, in the context of

a CAUTION, indicates a potentially

hazardous situation which if not avoided

could result in minor to moderate injury or

damage to the equipment.

Note: This symbol, in the context of a

replacement equipment or parts. Before

use, confirm that the product has not

been altered in any way.

Note: Unauthorized repair of your meter

will invalidate the warranty. For additional

information, contact Technical Support at

customerservice.sg.wai@thermofisher.com

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.

a. Locate the two slots on the meter power input.

b. Align the two tabs on the power adapter

connector with the two slots on the meter

power input.

c. 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.
