Product Features
Ø Colored touched screen, humanized operation interface make users completely monitor controller’s working status and real-time data.
Ø Inbuilt feed water pressure test gauge to real time monitor tap water pressure and filters blocking.
Ø Lifetime of PP cotton, activated carbon filter, RO membrane and ultra purification columns can be set to display the elapsed&rest time of consumables. Automatic reminder for filter replacement to avoid water quality decreasing.
Ø Feed water, RO and UP water three ways water quality sensor and five ways switches signal are accessed integrated, with functions of timing quantitative water taking.
Ø Equipped with USB Host interface, it supports data export function of historical alarm record and historical water intake record.
Ø Low-voltage 24VDC is used as the main power supply, which meets the safety regulations and meets the requirements of humid environment, and will not cause personal injury.
Ø Can be with inner circulation system to ensure water quality keep at the highest level. ( optional)
Application
Atomic absorption/emission spectroscopy, mass spectrum, TOC detection, environmental monitoring, biochip development, trace organic matter analysis
