GENERAL DESCRIPTIONGENERAL DESCRIPTION

GENERAL DESCRIPTION

The HI 93735 meter measures the total hardness in drink-

ing, surface and wastewater.

The meter uses an exclusive positive-locking system to ensure

that the cuvet is in the same place every time it is placed

into the measurement cell.

The reagents are in liquid and powder form and are

supplied in bottles and in packets. The amount of reagent

is precisely dosed to ensure maximum repeatability.

Display codes aid the user in routine operations.

The meters have an auto-shut off feature that will turn the

instrument off after 10 minutes of non-use.

This indicates that the meter is in a

ready state and zeroing can be per-

formed.

Sampling in Progress. This prompt ap-

pears each time the meter is performing

a measurement.

This indicates that the meter is in a

zeroed state and measurement can be

performed.

Under range. A flashing value lower

than the minimum concentration read-

able (see specifications) indicates that the

sample absorbs less light than the zero

reference. Check the procedure and make

sure you use the same cuvet for reference

(zero) and measurement.

Over range. A flashing value higher than

the maximum concentration readable (see

specifications) indicates that the sample

absorbs too much light, meaning that

the concentration is too high. Dilute the

sample.

Light over range. The cuvet is not in-

serted correctly and an excess ambient

light is reaching the detector. If the cover

is properly installed, then contact your

dealer or the nearest Hanna Customer

Service Center.

Light under range. The zero sample is

too dark for proper zeroing. If this is not

the case, contact your dealer or the

nearest Hanna Customer Service Center.

The "LOW BATTERY" indicates that the

battery voltage is getting low and the

battery needs to be replaced.
