Critical Industrial Applications & Technical Strengths

Why Ozone Monitoring is Essential

Ozone ($O_3$) is a powerful disinfectant widely used for water purification due to its eco-friendly residue-free breakdown. Accurate testing is crucial across:

Bottled Water & Beverage Industry: Ensuring microbial safety without altering taste
Pharmaceutical & Ultrapure Water: Routine monitoring in WFI (Water for Injection) loops
Commercial Swimming Pools & Aquariums: Maintaining ideal ozone levels for pathogen inactivation
Municipal Wastewater Treatment: Advanced oxidation processes (AOP) for tertiary effluent

Qiwei Technical & OEM Advantages

Designed to support laboratory distributors, water equipment integrators, and international brands:

High Stability Optics: Premium silicon photodiode and LED light source ensure long service life
Pre-dosed Reagents: Sealed reagent powder pillows and liquid reagents prevent oxidation degradation
OEM & ODM Customization: Custom branding, UI localization, and private label packaging
Internal Links: Combine with our COD Analyzers and Ammonia Testers for comprehensive water quality management.

Frequently Asked Questions (Ozone Analyzer Sourcing Guide)

Q1: What method do Qiwei Ozone Photometers use to measure dissolved ozone?

Our ozone meters utilize the standard DPD (N,N-diethyl-p-phenylenediamine) or Indigo trisulfonate photometric method, providing rapid, accurate, and repeatable concentration readouts in water samples.

Q2: Does dissolved chlorine interfere with dissolved ozone readings?

When both ozone and chlorine exist in water, specialized masking agents or differential measurement steps are provided with our reagent kits to eliminate chlorine interference for reliable ozone readings.

Q3: What is the shelf life of Qiwei ozone test reagents?

Our pre-dosed powder pillows and liquid reagents are vacuum sealed and typically offer a shelf life of 12 to 24 months when stored under standard cool, dry laboratory conditions.
