Overview
<span style="background-color:rgb(252,252,252);color:rgb(13,13,13);">Labtro Ultrapure Water System LT-UWS104 produces RO, DI, and ultrapure water at a rate of 45 L per hour. Its fully automatic microcomputer-controlled LCD panel displays operating status while monitoring RO conductivity and UP or DI water resistivity in real time. This ultrapure water system uses PP filtration, activated carbon, a 400 GPD RO membrane, dual-wavelength UV treatment, ion-exchange purification, and a 0.2 µm terminal filter to maintain consistent water quality. Three separate outlets provide convenient access to RO, DI, and ultrapure water, while high- and low-pressure protection, water-quality alarms, automatic flushing, and filter-replacement reminders support reliable operation. The floor-standing unit includes a large purification tank and mobile trundles for convenient installation and movement.</span>
