The ECO410 is deliberately focused on the essential functions of measurement technology for reliable measurement of the O2 concentration in gases. Essential for reliability and durability are the sensors used, GOEL 370 and GOEL 381, especially suitable for wet environments. The devices also impress through their ergonomics, water protection and display lighting. As a result, the ECO410 is a cost-effective and precise immersion gas meter, but is also a good value entry for many other oxygen measurementsfor example, for inert gas measurements.DisplayThe three-line LCD display provides ergonomic wide-angle visibility thanks to the backlightduring the day and at night. The HOLD function makes it possible to freeze the displayed values.Power Supply2 powerful AA-batteries, the power-saving design and the configurable automatic switch-off provide for a long operation. Configurable LCD-background lighting for other power saving possibilities.Reading range0.0 to 100.0 vol.% O Recommended
