Overview
The WG Series is a water purifier convenient for large capacity applications and compliant with JIS K0557 A4 water quality. It uses two independent dispensers, for ion-exchanged water and distilled water respectively, so operators can select the appropriate water type for different applications. The line features a 7-inch LCD touch panel for improved visibility and operability, along with consumables management functions that track replacement history and notify users when maintenance is due.
Dual Dispenser System
Two independent dispensers are provided for ion-exchanged water and distilled water, allowing water sampling to suit various scenes, and the amount of distilled water can be changed easily.
Precision Water Sampling
Supports fixed-quantity, continuous, and semi-automatic water sampling modes, with a patent-pending dripping control feature for precise marking-line alignment.
Touch Panel Interface
A 7-inch LCD touch panel system improves visibility and operability.
Consumables Management
Displays the replacement history of consumables and notifies users of upcoming and due replacements, with the notification cycle adjustable.
Compact Footprint
The width and depth have become more compact compared to the previous WG1001 model, allowing installation in a smaller space.
