GENERAL DESCRIPTION
Remove the instrument from the packing material and examine it care-
fully to make sure that no damage has occurred during shipping. If there
is any damage, notify your dealer.
The meter is supplied complete with
• Mounting brackets
• Transport splash-proof cover
• Instructions manual.
Note: Conserve all packing material until the instrument has been
observed to function correctly. Any defective item must be
returned in its original packing.
HI 8410 is a panel-mounted DO controller designed for simplicity of
use in a wide range of industrial process applications.
Dissolved Oxygen is indicated in mg/L (ppm) or in % of saturation in accor-
dance with the selection switch on the front panel. The temperature can be
measured in the range from -5 to 50 °C. The Dissolved Oxygen readings are
automatically compensated for the temperature effects on the oxygen solu-
bility and membrane permeability. Moreover, the salinity compensation
feature allows the determination of Dissolved Oxygen even in salty waters.
The instruments are designed with a standard DIN panel mount with
membrane keypads and large LCD with backlight on the front, and pro-
vide a series of auto-diagnostic functions.
Probes, power supply, contacts and recorders are connected on the rear
panel through screw terminals.
For control applications use the HI76410/4or HI 76410/10 galvanic probes.
The D.O. probe is provided with a membrane covering the galvanic sen-
sor and a built-in thermistor for temperature measurement and compen-
sation. The Oxygen that passes through the membrane causes an electric
current flow, from which the oxygen concentration is determined.
Other features include: recorder output in 0-20 mA or 4-20 mA configura-
tion; LED indicators which identify whether the controller is in operation
mode or setup selection mode; overtime control function; hysteresis setting.
The instrument is supplied with a plastic front cover and two mounting
brackets. Power cables are not included.
Note:In order to avoid erroneous readings never use both 0-20 mA and
4-20 mA recorder outputs at the same time.

MECHANICAL DIMENSIONS
OF HI8410
Front view of the panel-mounted unit
These dimensions show the cutout size for the installation.
Side view of the panel-mounted unit
Adjustable location brackets (supplied with the meter) allow the indicator
to slide into the cutout and will hold the unit securely in place. 190 mm
(7.50") is the minimum amount of room required to install the indicator
with the cables connected.

All Hanna D.O. probes are shipped dry. To hydrate the probe and prepare
it for use proceed as follows:
1. Remove the black & red plastic cap. This cap is used for ship-
ping purposes only and can be thrown away.
2. Insert the supplied O-ring in the membrane
(see figure).
3. Rinse the supplied membrane (HI 76410A) with electrolyte
while shaking it gently. Refill with clean electrolyte. Gently tap
the membrane over a surface to ensure that no air bubbles
remain trapped. To avoid damaging the membrane, do not
touch it with your fingers.
4. With the sensor facing down screw the cap clockwise to the end
of the threads. Some electrolyte will overflow.

•Recorder Output (terminals 1, 2, 3)
These contacts are used for connec-
tion to a recorder output. The output
can be 0-20 mA or 4-20 mA and is pro-
portional to the measured Dissolved
Oxygen values.
Connect the “+” wire from the recorder to terminal 1 on the instru-
ment and the other wire (common) to terminal 2 for 4-20 mA re-
corder output or terminal 3 for 0-20 mA recorder output.
Note:Only one recorder output connection is permited. In order to avoid
malfunction leave unconnected the unused terminal.
REAR CONNECTIONS FOR HI 8410
• Power Connection Terminals
4-screw-terminal-strip for connection
to a 3-wire power cable according to
the indicated voltage (115 or 230V).
• Probe connection
For connection of the HI76410 DO
probe. Connect the wires according with
the indicated color.
• Set Contacts
Dosing pumps or other control equip-
ment may be connected to the "SET"
(Max. 2A, 240 V) terminals (1, 2).
These contacts act only as a "dry"
switch allowing electrical continuity,
not as a power supply.
