This is a ultrapure water production device that produces pure water (DI water) equivalent to JIS K0557 A3 grade. (It has a built-in 12L pressurized container.)
Fully automatic electronic control eliminates the need for complex settings. It can purify ultrapure water with a resistivity of 18.25 MΩ.cm, conductivity of 0.055 μS/cm, and organic matter content of <1 CFU/mL. The LED display shows the status of the device in real-time, including "water purification," "cleaning," "full tank," and "low water." In the event of a malfunction, the backlight color changes to indicate a warning. It features a built-in RO membrane automatic cleaning program (self-cleaning every seven days), a self-test at startup, a low water protection alarm, and an automatic reset function during power outages. Available in two types: tabletop and wall-mounted, with four models to choose from based on purification capacity. The water quality corresponds to A3 of JISK0557 "Water used for testing water supply and drainage." It includes a built-in 12L pressurized container.
