Stratos^® Pro

 Ground-breaking process analyzers for pH and ORP measurement

High-contrast, easily legible widescreen display. Unique user prompting with functional colored backlighting.

For connection of all common analog and digital sensors (also contactless) with significantly enhanced predictive diagnostics.

Thanks to innovative enclosure technology, they are ideally suited for use in virtually any environment. For hazardous and safe areas.


New operating concept
The Stratos® Pro series realizes a completely new and especially user-friendly operating concept in modern analyzers. Studies have shown that operator errors more frequently lead to downtime than hardware defects or malfunctions and faulty measurements.
A user-friendly design and intuitive operation has been given the highest priority in the new series.


Setting the standard
The unique backlit display of the Stratos® Pro display changes between six different colors to clearly signal operating states. For example, the normal measuring mode is backlit white, while displays in the information mode appear in green and the diagnostic menu in turquoise. The orange HOLD mode, e.g. with calibrations, is just as visible as the magenta color for optical emphasis of asset management messages for predictive diagnostics – such as maintenance request, pre-alarm, and sensor wear.


The alarm status has a particularly noticeable red display color and is also signaled by flashing display values. Unreliable entries or false passcodes cause the entire display to blink red so that operating errors are noticeably reduced.


Clarity of display
A pin-sharp and high-contrast LC display provides optimum legibility, even in the most difficult lighting conditions. Instead of pixilated elements which are sometimes difficult to identify, the display utilizes high-resolution, self-explanatory icons. Longer text displays are scrolled horizontally in large, clearly legible font: a scrolling ticker line is more easily and reliably comprehended than text in jumping lines.

Tough
The reinforced and UV-resistant plastic enclosure of the Stratos® Pro supports the product functionality. There are neither prominent control elements nor those with a high mechanical load to be found on the virtually plane, dirt-proof front panel. Injection molded, directly sealed keys are made from high-quality EPDM so that it is no longer necessary to stick films, which had to perform a sealing function, onto the front of the device.
The high IP 67 rating is maintained under all conditions – reliable and safe operation is guaranteed in the range from –20°C to +65°C, even for operation in hazardous locations.

All-round resilience
The display window of the Stratos® Pro is connected directly to the plastic enclosure during the innovative molding process. It is made from reinforced safety glass, is scratch-resistant and UV-resistant. All the device's electronics are completely encapsulated in the door module: there are no exposed PCBs. The large rear unit can be mounted separately. All electrical connections are made by means of screw terminals in the door unit, so that if the door module is replaced, the complete cable guide can be retained in the rear unit.

The new benchmark
A number of outstanding technological properties make the Stratos® Pro series the new benchmark for 2-wire analyzers. Colored screen backlighting has been realized for the first time in this device class, with the lowest possible electrical power.
In contrast to all 2-wire devices previously available on the world market, two digital inputs are available as well as an analog input plus a second output for another measured value.

• The new benchmark for 2-wire devices
• Full functionality with 2-wire supply
• –20 °C to +65 °C permitted also for hazardous-area applications
• Operation of contactless sensors
