WARRANTY

HI 98311 and HI 98312 are warranted for one

year against defects in workmanship and materials

when used for their intended purpose and maintained

according to instructions. The probe is warranted

for a period of six months. This warranty is limited

to repair or replacement free of charge.

Damages due to accident, misuse, tampering or lack

of prescribed maintenance are not covered.

If service is required, contact the dealer from whom

you purchased the instrument. If under warranty,

report the model number, date of purchase, serial

number and the nature of the failure. If the repair is

not covered by the warranty, you will be notified of

the charges incurred. If the instrument is to be re-

turned to Hanna Instruments, first obtain a Returned

Goods Authorization Number from the Customer

Service department and then send it with shipment

costs prepaid. When shipping any instrument, make

sure it is properly packaged for complete protection.

All rights are reserved. Reproduction in whole or in

part is prohibited without the written consent of the

Waterproof

EC/TDS/Temperature Testers

Remove the instrument from the packing material and

examine it carefully. If any damage has occurred

during shipment, immediately notify your Dealer or

the nearest Hanna Customer Service Center.

Each meter is supplied with:

• HI 73311 EC/TDS probe

• HI 73128 probe removal tool

• batteries (4 x 1.5V) and instructions

Note: Conserve all packing material until the instru-

ment has been observed to function correctly.

Any defective item must be returned in its

original packing.

PRELIMINARY EXAMINATION

HI 98311 and HI 98312 are waterproof EC/TDS and

temperature meters. The housing has been completely

sealed against humidity and designed to float.

All EC/TDS readings are automatically temperature

compensated (ATC), and temperature values can be

displayed in °C or °F units.

The EC/TDS conversion factor (CONV) is selectable by

the user, as well as the temperature compensation

coefficient β (BETA).

The meters can be calibrated at one point.

Measurements are highly accurate with a unique

stability indicator right on the LCD.

A low battery symbol warns the user when the batter-

ies are to be replaced. In addition the Battery Error

Prevention System (BEPS) avoids erroneous reading

caused by low voltage level by turning the meter off.

The HI 73311 EC/TDS probe, supplied with the

meter, is interchangeable and can be easily replaced

by the user.

The stainless steel encapsulated temperature sensor

facilitates faster and more accurate temperature mea-

surement and compensation.

Recommendations for Users

Before using this product, make sure that it is entirely suit-

able for the environment in which it is used. Operation of

this instrument in residential areas could cause unaccept-

able interferences to radio and TV equipment.

Avoid touching the probes at all times.

Any variation introduced by the user to the supplied equip-

ment may degrade the instrument’s EMC performance. To

avoid electrical shock, do not use this instrument when volt-

ages at the measurement surface exceed 24 Vac or 60 Vdc.

To avoid damages or burns, do not perform any measure-

ment in microwave ovens.
