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
HI 76410/4
or
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.
