The HI8410 is a panel mounted dissolved oxygen controller that is used to maintain and monitor the concentration of DO in a wide range of industrial process applications. The HI8410 uses a Galvanic probe that typically requires less maintenance than a Polarographic style making it ideal for long term monitoring.
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.
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.
