Beifen Sanpu CY-1A Ozone Analyzer

Overview

The Beifen Sanpu CY-1A Ozone Analyzer is a portable, laboratory-grade photometric instrument engineered for accurate, on-site quantification of aqueous ozone concentration in water treatment applications. It operates on the principle of photometric colorimetry—specifically, the selective reaction of ozone with a proprietary indigo trisulfonate or DPD-based reagent, generating a stable colored complex whose absorbance is measured at a defined wavelength (typically 600–620 nm) using a precision LED light source and silicon photodetector. This method conforms to internationally recognized colorimetric protocols referenced in standard methods for drinking water analysis and provides traceable, reproducible results without reliance on subjective visual interpretation. Designed for routine monitoring in municipal water plants, industrial process streams, swimming pool systems, and bottled water production lines, the CY-1A delivers rapid, field-deployable measurements aligned with operational control limits required under regulatory frameworks governing disinfectant residual management.

Key Features

• Microprocessor-controlled photometric detection system with automatic zero adjustment and five-point built-in calibration curve selection, supporting non-linear interpolation and digital signal smoothing for enhanced low-range accuracy.
• Dedicated long-life LED optical source with integrated thermal and current regulation—eliminates warm-up delay and ensures spectral stability over time; rated for >20 years of continuous operation under normal use conditions.
• High-contrast backlit LCD display with 0.01 mg/L resolution and full-scale range of 0–2.5 mg/L, optimized for readability in both indoor lab and outdoor ambient lighting environments.
• Integrated rechargeable lithium-ion battery (2-hour charge yields up to 4 hours of continuous measurement), coupled with universal AC/DC adapter compatibility—enabling seamless transition between fixed-lab and mobile field deployment.
• Vacuum-sealed, single-use reagent packaging minimizes oxidation exposure and extends shelf life; each kit includes pre-measured reagents compatible with standardized reaction protocols per GB/T 5750.11–2006.
• Firmware-embedded data retention architecture preserves calibration coefficients, measurement history, and user settings during power interruption—no manual reconfiguration required after shutdown.

Sample Compatibility & Compliance

The CY-1A is validated for direct analysis of clear, low-turbidity water samples—including treated potable water, ozonated process water, cooling tower effluents, and recirculated pool water. Sample matrix interference from chlorine, chloramines, or hydrogen peroxide is mitigated through timed reaction kinetics and optional quenching agents supplied separately. Instrument performance meets the metrological requirements outlined in GB/T 5750.11–2006 “Standard Methods for the Examination of Drinking Water – Disinfectants and Disinfection By-products”, and its analytical methodology is consistent with EPA Method 334.0 (Indigo Colorimetric Method) and ISO 10707:2018 (Water quality — Determination of ozone — Spectrophotometric method). While not certified for GLP or FDA 21 CFR Part 11 compliance out-of-the-box, audit-ready data export functionality (via optional USB interface module) supports integration into regulated QA/QC workflows requiring traceable electronic records.

Software & Data Management

The CY-1A operates autonomously without external software dependency; all calibration, measurement, and data handling are performed onboard via embedded firmware. Internal memory stores up to 500 measurement records with timestamp, sample ID (user-entered), and calibration version metadata. Optional PC connectivity (via TTL-to-USB adapter, sold separately) enables CSV export of raw and processed datasets for trend analysis in Excel or LIMS platforms. Firmware updates are delivered via microSD card slot, supporting version-controlled instrument validation and periodic recalibration verification logs required under internal quality management systems.

Applications

• Real-time verification of ozone dosage efficacy in municipal drinking water disinfection stages.
• Monitoring residual ozone levels in pharmaceutical-grade purified water (PW) and water-for-injection (WFI) distribution loops.
• Validation of ozone contact time (CT) values in compliance with US EPA Surface Water Treatment Rule (SWTR) guidelines.
• Process optimization in food & beverage processing where ozone serves as a non-thermal sanitizer for rinse water and CIP solutions.
• Educational laboratories conducting method validation studies for colorimetric oxidant assays.

FAQ

What ozone detection method does the CY-1A employ?
It uses standardized photometric colorimetry based on the reaction of ozone with a stabilized DPD or indigo derivative, measured at a fixed visible wavelength.
Is the instrument suitable for turbid or colored water samples?
Best performance is achieved with clarified, low-absorbance samples (turbidity < 1 NTU); high turbidity or background color may require filtration or method-specific correction.
How often must the calibration curve be updated?
Factory calibration remains valid for 12 months under typical storage and usage; field recalibration is recommended before each daily shift or after reagent lot changes.
Does the CY-1A support regulatory reporting formats?
Raw data export supports CSV formatting for import into validated LIMS or statistical process control (SPC) tools; full 21 CFR Part 11 compliance requires supplemental access controls and electronic signature modules.
Can the device measure gaseous ozone?
No—the CY-1A is strictly configured for aqueous-phase ozone quantification; gas-phase ozone analysis requires dedicated UV absorption or electrochemical sensors with appropriate sampling manifolds.
