When developing the ECO 51x series, the focus was placed on the essential functions of measurement technology.
Pure measurement with a focus on precision, speed and reliability, packaged in a compact housing, is what makes the outstanding price-performance ratio, Made in Germany, possible.
The handheld meters also impress with their ergonomic design, dust and water-protected design in accordance with IP 65/67 and the illuminated display.
The compact pH meters are a real alternative to pH sticks on the one hand and high-priced, complex devices on the other.
The ECO 510 meter enables measurements in the pH range, while the ECO 511 also offers the option of pH/redox measurements with a temperature input (Pt1000)

Applications
The measuring devices can be used in aquaristics, aquaculture and water monitoring, plant cultivation, agriculture, laboratories, quality assurance, service and food.
Applications without temperature input necessary: Measuring in pools, well-water, etc.: Temperature is constant – can be entered manually once.
Applications where temperature input of ECO 511 is recommended: Field measuring, e.g. surface water, wastewater, etc.: Temperature is compensated most precise and comfortable!
Display
Thanks to backlight, the three-line LCD display offers ergonomic wide-angle visibility – by day and night.
Power supply
2 powerful AA batteries, the energy-saving design and the configurable automatic switch-off function ensure long operation.
Configurable LCD backlight for additional energy-saving options.
