Applications: PCR applications and analysis; meteorological analysis; precision instrument analysis; amino acid analysis; preparation and dilution of analytical reagents and chemicals; liquid chromatography; medical biochemical analysis instruments; gas chromatography; atomic absorption, atomic fluorescence, and atomic emission spectroscopy; ion chromatography; and plasma emission spectroscopy.
7-inch extra-large color touchscreen with an animated menu control system.
Displays water quality and temperature for three water streams—inlet water, RO water, and UP water—enabling real-time monitoring.
Automatic alerts for expired consumables to prevent a decline in water quality.
System password protection prevents unauthorized data changes.
Regular automatic circulation ensures stable water quality.
Circulation system can be freely started or stopped.
Compatible with two pure water storage methods: pressurized water barrels and level-sensing water tanks; water level and storage volume are displayed directly.
Fixed-volume water dispensing function (1–999,999 ml).
Conductivity-based water dispensing function (0.1–18.25 MΩ·cm).
Comprehensive information query and data management functions provide full oversight of system operation status, water quality, consumable usage, and historical alarms.
Standard USB port allows connection to a printer for printing historical water quality and water usage records.
Standard one-touch disinfection module for rapid disinfection of RO membranes, recirculation lines, and water tanks, ensuring extremely low bacterial contamination levels.
System time settings (year/month/day/hour/minute), timed standby (0–60 min), and timed shutdown (0–24 h) functions.
The service life of the pre-treatment unit, RO membrane, UV lamp, and ultrapure water cartridge can be freely set, and the system displays the usage and remaining time of consumables.
Built-in automatic timed flushing function to prevent scale buildup on the RO membrane, extending its service life.
All-plastic housing, rust-free.
