ECO 410(T)-MAX - O₂-Analyser / air oxygen meter (formerly G 1690)

The ECO 410 / 410T deliberately focuses on the essential functions of measurement technology for reliable measurement of the O2 concentration in gases. The sensors used, GOEL 370 and GOEL 381, which are especially suitable for wet environments, are essential for reliability and durability.

The devices also impress with their ergonomics, water protection and display backlight.

This makes the ECO 410 / 410T an inexpensive and precise immersion gas detector, but it is also an inexpensive yet high-quality entry-level device for many other oxygen measurements - for example inert gas measurements.

ATTENTION:
The device is used for additional control. It does not replace an approved measuring device or safe methods for creating gas mixtures!

Display
Thanks to the backlight, the three-line LCD display offers ergonomic wide-angle visibility - by day and by night.
The HOLD function enables the display values to be frozen.

Power supply
2 powerful AA batteries, the energy-saving design and the configurable automatic switch-off function
ensure long operation.
Configurable LCD backlight for further energy saving options.
