Description

ECO 521 – waterproof compact EC-meter – conductivity-meter ( formerly G 1409)

The primary focus in the development of the newECO 521 Conductivity Meter ECO-line was place on the essential functions of the measurement technology.
Pure measurement with a focus on precision, speed and reliability packaged in a compact housing distinguishing an impressive price/performance ratio, Made in Germany.
The new handheld measuring devices also impress with their ergonomic design, dust and water-protected design in accordance with IP 65/67 and the illuminated display.
The measuring devices with the high-precision sensor can be used up to 5000 µS/cm and are therefore cost-optimized professional devices for use in the areas

Aquaculture, hydroponics, plant breeding
Water treatment (e.g. osmosis plants)
Boiler feed water / heating construction
and many more…

The long-term stable titanium measuring cell can be calibrated with GKL 100 calibration solution, the integrated temperature sensor compensates temperature changes very quickly and accurately.
The ECO 521 – a reliable professional device for daily use as an alternative / upgrade to entry-level measuring sticks!

The ECO 521 is a reliable, easy-to-use handheld conductivity meter designed for accurate measurement of electrical conductivity (EC), total dissolved solids (TDS), and temperature in aqueous solutions. Built with a durable waterproof design, automatic temperature compensation, and replaceable conductivity cell, the ECO 521 is ideal for field testing, environmental monitoring, laboratories, agriculture, hydroponics, and water treatment applications.
