Fail Safe Alarm Syste
Hanna’s exclusive Fail Safe Alarm System protects against problems caused by power supply failure or signal interruption, which are typical risks in industrial environments. An alarm condition is indicated by a red LED, located directly on the front panel of the controller.
Automatic Temperature Compensation
The Dissolved Oxygen readings are automatically compensated for the temperature effects on the oxygen solubility and membrane permeability.
Salinty Compensation
The salinity compensation feature allows the determination of Dissolved Oxygen even in salty waters.
Simple to Use
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.
Analog Output
To enhance troubleshooting and the ability to record data while monitoring, simply attach a recording device to the instrument’s 4 to 20 mA output contacts, conveniently located on the front panel, to obtain a copy of the results on demand.
Diagnostic Tests
The HI 8410 controllers are designed with built-in diagnostic functions to enable the user to check and troubleshoot the instrument. The checks performed are through the front panel keys and can be used to isolate the cause of malfunction.
