ECO 523 - high resolution ultrapure water conductivity meter (formerly G 1420)

When developing the new ECO line, the focus was deliberately 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 possible.
The new handheld measuring devices also impress with their ergonomic design, dust and water protection in accordance with IP 65/67, and illuminated display.
The ECO 522 is a universal wide-range conductometer with a robust 2-pole measuring cell for measurements ranging from deionized water (cleaning processes, aquariums) to seawater with up to 100.0 mS/cm.
The ECO 523 is equipped with a stainless steel ultrapure water measuring cell and specializes in high-resolution measurement of ultrapure water, alcohol, solvents, and similar substances. The resolution is up to 0.001 μS/cm.
