GENERAL DESCRIPTION

The HI 93828 meter measures the nitrate (NO
water and wastewater in the 0 to 100 mg/L (ppm) range.

The meter uses an exclusive positive-locking system to ensure
that the cuvet is in the same position every time it is placed
into the measurement cell.

The reagents are in powder form and are supplied 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.

DISPLAY CODE GUIDE

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.

V

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.
