GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION
The HI 93721 meter measures the iron content in water
and wastewater in the 0.00 to 5.00 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 reagent is in powder form and is supplied in packets.
The amount of reagent is precisely dosed to ensure maxi-
mum repeatability.
Display codes aid the user in routine operations.
The meter has 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.
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 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 "V" indicates that the battery volt-
V
age 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 bat-
tery to restart.
