The HI 93715 meter measures the ammonia nitrogen (NH

N) content in water, wastewater and seawater in the 0.00 to

9.99 mg/L (ppm) range.

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 form and are supplied in bottles.

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.

Preliminary Examination

General Description

Specifications

IST93715R4 11/06

This indicates that the meter is in a ready

state and zeroing can be performed.

Sampling in Progress. This prompt appears

each time the meter is performing a

measurement.

This indicates that the meter is in a zeroed

state and measurement can be performed.

A zero reading was not taken. Insert a

sample before adding reagent and press

ZERO.

Under range. A blinking "0.00" 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 inserted

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 "V" indicates that the battery voltage

is getting low and the battery needs to be

replaced.

This indicates that the battery is dead and

must be replaced.

Note: once this indication is displayed,

the meter will lockup. Change the battery

to restart.
