The acronym stands for Operation Without Supervision as it is mentioned in the specific rules and regulations of the TÜV for boiler houses. The DUROMAT XX analyzer indicates whether a enough stock of reagent is available for at least the next 72 hours.
Efficient reagent consumption
The reagent bottle can easily be exchanged. A 500 ml bottle allows more than 5,000 analyses.
Extensive alarm functions
If the limit value is exceeded, an alarm is emitted by switching a potential-free relay. This alarm output can be placed on a control room for signaling purposes or used to operate a horn, to close a valve or to head on a program for the regeneration of a water softening plant.
If you encounter technical problems with the device, a fault message is issued by switching a potential-free relay. The detailed diagnostic program guides you step by step through all functions in an easy to understand way. Thus, the device is roundly checked, and the cause of the error message is clearly located.
Minimal maintenance effort
The measuring chamber must be cleaned depending on the set measuring interval or the frequency of measurements. The reagent hoses and sealing rings typically need to be replaced only once or twice a year. No additional tools are required for maintenance. It is very easy to perform.
The device is hung directly on a wall or supporting structure. Installation and commissioning are an intuitive process.
The potential-free switch of a flow meter, a timer or any other state switch can be connected to this input. When the contact is open, no analyses are run in the programmed interval. Alternatively, this input can be used as start input for analyses. In the quantity interval mode, the water meter is connected to the input.
Three potential-free relay outputs
The potential-free relay outputs can be used to report a limit value alarm, a device fault or an active analysis as a status e.g. to a control room. Alternatively, signaling devices or solenoid valves can be switched.
