The HI 93746 meter measures the iron content in water,
wastewater and seawater in the 0 to 400 µg/L (ppb)
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 reagent is in powder form and is 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.

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" 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.
