What Is a Hydrogen Peroxide Analyzer?
A hydrogen peroxide analyzer is an instrument that continuously measures the concentration of hydrogen peroxide (H₂O₂) dissolved in water. The Bebur BT6308-Peroxi hydrogen peroxide analyzer uses a membrane sensor that requires no reagents or buffers — measurement is stable and performance reliable, reducing maintenance workload and lowering operating cost.
Hydrogen peroxide is a powerful oxidizing disinfectant. Its sterilization performance — and the safety of the final product — depends on holding the H₂O₂ concentration within a precise window: under-dosing compromises disinfection, while over-dosing leaves residual peroxide that must be removed downstream. Continuous online measurement keeps that window under control around the clock.
The analyzer supports drinking water, wastewater, industrial process water and purified water disinfection, as well as brine applications — from bottle washer dosing and CIP plants to food washing water bleaching and pharmaceutical production.
How Does a Hydrogen Peroxide Analyzer Work?
- Sample flows through the cell. The water sample passes the sensor in a flow cell at approximately 0.5 L/min, providing a stable, representative measurement stream.
- H₂O₂ diffuses through the membrane. Hydrogen peroxide diffuses from the sample through the sensor membrane into the electrolyte zone, which is separated from the water sample.
- A proportional signal is generated. At the working electrode, the hydrogen peroxide produces an electrical signal proportional to its concentration; the dual-electrode system automatically adjusts its potential to eliminate zero drift.
- The reading is compensated and output. The signal is amplified by the sensor electronics, and an integrated temperature sensor applies automatic temperature compensation before the value is displayed and transmitted.
The membrane design requires no additional reagents or buffers, and calibration is one-point (span) only — no zero calibration is ever needed. The measurement is unaffected by cleaning agents present in the water.
Key Features
Membrane Amperometric Sensing
Membrane-based amperometric polarographic dual-electrode sensor delivering stable performance and accurate measurement over a long service life.
Reagent-Free Operation
No chemical reagents and no buffers needed — reduced maintenance workload and lower cost of ownership.
No Zero Calibration
Self-adjusting electrode potential eliminates zero drift; only one-point span calibration is ever required.
Unaffected by Cleaning Agents
The measurement is not influenced by cleaning agents in the water — ideal for bottle washing and CIP environments.
Five Measuring Ranges
From 0.5–200 mg/L residual monitoring up to 500–100000 mg/L high-concentration process control on one sensor platform.
Drinking Water to Brine
Suitable for drinking water, process water and brine, with automatic temperature compensation from 0 to 45 °C.
