PRELIMINARY EXAMINATION
Remove the instrument from the packing material and examine it carefully
to make sure that no damage has occurred during shipping. If there is any
damage, please contact your local Hanna Instruments Office.
The meter is supplied complete with:
• Mounting brackets
• Transport splash-proof cover
• Instructions manual
• Quality Certificate
Note: Conserve all packing material until the instrument has been
observed to function correctly. Any defective item must be returned
in its original packing.
H8410 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
accordance with the selection switch on the back 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 solubility 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
provide 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 HI76410/4 or HI76410/10 galvanic
probes. The DO probe is provided with a membrane covering the gal-
vanic sensor and a built-in thermistor for temperature measurement and
compensation. 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 configu-
ration; 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.
