returned in its original packing.
GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
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 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 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 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 configuration; 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.
