USER MANUAL

AD31 & AD32

Waterproof EC/TDS Testers

Dear Customer,

Thank you for choosing an Adwa product.

Please read carefully this manual before

starting operations.

This instrument is in compliance with the

EMC directive 2004/108/EC and its stan-

dards, and Low Voltage Directive 2006/95/

EC and its standards for electrical equip-

ments.

For additional technical information, please

e-mail us at [email protected].

INTRODUCTION

AD31 and AD32 are waterproof EC, TDS and

temperature testers. The housing has been

completely sealed against humidity.

All EC and TDS readings are automatically

temperature compensated (ATC), and

temperature values can be displayed in °C

or °F units.

The EC/TDS conversion factor (CONV) can

be selected by the user, as well as the coefficient

β (BETA) for temperature compensation. The

instruments can be calibrated at one point.

Measurements are highly accurate with a

unique stability indicator right on the LCD.

The models are also provided with a low

battery symbol which warns the user when

the batteries need to be replaced.

The AD32P probe supplied with the meters,

is interchangeable and can be easily replaced

by the user.

The encapsulated temperature sensor allows

fast and accurate temperature measurement

and compensation.

Each meter is supplied complete with:

•AD32P EC probe

•4 x 1.5V batteries, button type

•User manual
