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

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 HI 76409/4 or HI 76409/10 galvanic probes.

The DO probe is provided with a membrane covering the galvanic 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 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
