Hanna Instruments HI8410 Dissolved Oxygen Controller with Extended Range and Analog Output
In a variety of industrial process applications, the dissolved oxygen concentration is maintained and monitored using the panel-mounted dissolved oxygen controller (HI8410).
Long-term monitoring is made possible by the HI8410’s usage of a galvanic probe, which normally requires less upkeep than a polarographic design.
- Fail Safe Alarm System protects these meters against the pitfalls of process control.
- Low maintenance Galvanic probe.
Description
A panel-mounted DO controller called the HI 8410 was created to be simple to use in a variety of industrial process applications. According to the selection switch on the back panel, the amount of dissolved oxygen is displayed in mg/L (ppm) or in percent of saturation. Between -5 and 50 °C can be used to measure the temperature. The effects of temperature on oxygen solubility and membrane permeability are automatically taken into account when testing for dissolved oxygen. Additionally, the salinity correction feature makes it possible to measure dissolved oxygen even in fluids with a high salt content.
The instruments include a number of auto-diagnostic functions and are built with a standard DIN panel mount, membrane keypads, and huge LCD displays with backlights on the front. On the rear panel, screw terminals are used to connect the probes, power source, contacts, and recorders.
A membrane protecting the galvanic sensor and a built-in thermistor for temperature measurement and correction are both included with the DO probe.
The oxygen concentration is calculated from the electric current flow that the oxygen causes to occur as it passes across the membrane. Other functions include overtime control function, hysteresis setting, recorder output in 0-20 mA or 4-20 mA configuration, LED indications that show whether the controller is in operating mode or setup selection mode. Two mounting brackets and a plastic front cover for the instrument are included. There are no power cables supplied.
HI8410 FEATURES/BENEFITS:
Fail Safe Alarm System
- The unique Fail Safe Alarm System from Hanna guards against issues brought on by signal interruption or power supply failure, which are common dangers in industrial settings. A red LED on the controller’s front panel that is immediately facing the user shows an alarm situation.
Automatic Temperature Compensation
- The temperature effects on the oxygen solubility and membrane permeability are automatically taken into account when reading the dissolved oxygen levels.
Salinty Compensation
- Even in waters with a high salt content, the salinity compensation feature makes it possible to measure dissolved oxygen.
Simple to Use
- The instruments include a number of auto-diagnostic functions and are built with a standard DIN panel mount, membrane keypads, and huge LCD displays with backlights on the front.
Analog Output
- The instrument’s 4 to 20 mA output connectors, which are conveniently situated on the front panel, can be used to connect a recording device to improve troubleshooting and the capacity to record data while monitoring.
Diagnostic Tests
- The built-in diagnostic features of the HI 8410 controllers allow the operator to inspect and troubleshoot the instrument. The tests carried out using the front panel keys can be used to identify the malfunction’s root cause.
