Product Description

Product Description

Adrona Gradus EDI is fully integrated and compact pure and ultrapure smart tap water system. It has unique built-in dispensers that provide both ultrapure Grade 1 and pure Grade 2 water.
Gradus EDI systems are intended for use in laboratories with high daily pure and ultrapure water consumption. This allows a significant reduction in the operating costs of the water treatment system, as the EDI module does not need to be replaced.
The system requires external water tank and comes in 3 main configurations: Gradus EDI Trace, Gradus EDI LT, Gradus EDI Bio.
It has all-new electronics and software, providing a range of advanced features: large colour touch screen, data logging capability, a wide range of flow control options, drop-by-drop function, the ability to connect multiple remote dispensers, Ethernet and USB interfaces, dispense report preparation, improved accuracy of conductivity and TOC measurements.
