INTRODUCTION

AD33 and AD35 are waterproof EC testers.

The housing has been completely sealed against

humidity.

All EC readings are automatically temperature

compensated, and temperature values can be

displayed in °C or °F units.

EC calibration is automatic at one point, while

temperature range is factory calibrated and can

only be adjusted by the user.

The AD33P 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.

To prolong battery life, these models are pro-

vided with an auto-off feature that turns them

off after 5 minutes of non-use.

Moreover, when batteries become too weak to

ensure reliable readings the meter automatically

turns off.

Each meter is supplied complete with:

• AD33P EC probe

• 4 x 1.5V batteries, button type

• User manual
