Ultra pure water analyzer

Ultra pure water analyzer

  • Product Number:LD-CD10
  • Product Difference:Water output: 10 L/h; features a large touchscreen, dual resistance and conductivity displays, a sterile water tank, a sterilizing lamp, and a terminal filter

Product Introduction

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.

Product Features

  • 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, with displays for consumable usage and remaining time.

  • Built-in automatic timed flushing function to prevent scale buildup on the RO membrane, extending its service life.

  • All-plastic housing, rust-free.
