Introduction to Purified Water Quality Analysis (RO)

Analyzing the quality of ultrapure water from reverse osmosis (RO) systems by measuring the pH and electrical conductivity of permeate (ultrapure water) post-RO filtration is a complex process.

Due to the extremely low ion content in purified water, achieving accurate pH and conductivity measurements requires highly sensitive and advanced equipment.

This is precisely why a customer in the Food & Beverage industry in Vietnam chose to invest in two SWAN analytical instruments provided by Viet An: the “AMI pH-Redox QV-Flow AC” and the “AMI Powercon Specific.” These solutions purified water quality that meets stringent standards.

Instruments for Analyzing Purified Water Quality from RO Systems

AMI pH-Redox QV-Flow AC

This instrument is designed to accurately measure pH within a range of 1–12, with a resolution of 0.01 pHeven when the H+ ion concentration in ultrapure water from reverse osmosis systems is at minimal levels. This precision is critical to ensuring water meets the rigorous standards required for food and beverage production.

AMI Powercon Specific

Capable of measuring ultra-low conductivity down to 0.055 µS/cm,the sensor features a titanium 2-electrode design with automatic temperature compensation, making it ideal for the typical 2–5 µS/cm range from RO purified water The results are highly reliable, with a measurement error of only ±0.005 µS/cm.

  • Precise pH control helps reduce chemical dosing by 10–15%,while stable conductivity measurement extends the lifespan of RO membranes by 6–12 months.
  • The instrument operates reliably at temperatures up to 50°C and adapts to fluctuating feedwater conditions, minimizing risks in hot and humid climates.

Investing in SWAN purified water analysis instruments delivers not only high performance and reliability, but also a long-term sustainable solution. It is a cost-effective investment that offers exceptional value, helping your RO system run more smoothly and efficiently.

Quick Installation – Instant Results

A key advantage of SWAN instruments is their Plug & Play designenabling fast and hassle-free installation.
