Overview
The Junray ZR-5405 Ozone Aging Chamber Calibration System is a purpose-built metrological instrument engineered to verify and calibrate the critical environmental parameters inside ozone aging test chambers—specifically ozone concentration (O₃), temperature, and relative humidity. It operates on dual-principle measurement architecture: ultraviolet (UV) absorption photometry for ozone quantification at 254 nm (in accordance with HJ 590–2010), coupled with traceable platinum resistance (PT100) and capacitive polymer sensors for temperature and humidity, respectively. Designed for laboratory-based validation workflows, the system supports periodic calibration, intermediate checks, and performance verification of ozone aging chambers used in rubber, elastomer, and polymer material testing per ISO 1431-1, ASTM D1149, and GB/T 13642. Its primary function is not environmental simulation—but metrological assurance—ensuring chamber output remains within specified tolerances defined by JJF 2051–2023 (Calibration Specification for Ozone Aging Test Chambers) and aligned with GLP-compliant quality systems.
Key Features
- UV photometric ozone sensor with imported low-pressure mercury lamp (254 nm emission), offering long-term spectral stability, minimal drift (<±1.5% FS/year), and immunity to cross-sensitivity from NO₂ or VOCs.
- Integrated tri-parameter sensing module: high-accuracy PT100 Class A temperature probe (±0.15 °C @ 23 °C) and NIST-traceable capacitive RH sensor (±1.5% RH, 10–90% RH range).
- Onboard embedded data logger with ≥16 GB flash memory—supports continuous logging at user-defined intervals (1 s to 60 min), time-stamped with internal RTC (real-time clock, ±2 s/month).
- Modular mechanical architecture: field-replaceable sensor cartridges with quick-lock interface; no soldering or recalibration required after module swap.
- Adaptive digital filtering algorithm (IIR-based) dynamically adjusts time constant based on signal variance—enabling <10 s T₉₀ response for ozone while maintaining noise suppression below 0.5 ppb RMS.
- USB-C interface for direct data export (CSV/Excel-compatible format); optional Bluetooth 5.0 module enables wireless pairing with certified thermal printers for on-site calibration report generation.
Sample Compatibility & Compliance
The ZR-5405 is compatible with all standard ozone aging chambers having internal volumes from 0.1 m³ to 1.5 m³ and ozone concentration ranges of 25–500 ppm (v/v). It meets national metrological verification requirements under JJG 1077–2012 (Verification Regulation for Ozone Gas Analyzers) and fulfills technical validation criteria outlined in JJF 2051–2023—including linearity assessment (≤±2% of reading), repeatability (RSD ≤1.2%), and temperature/humidity coupling error evaluation. All sensors are calibrated against national primary standards maintained by CNIM (China National Institute of Metrology), with calibration certificates issued traceable to SI units. The system supports audit-ready documentation for ISO/IEC 17025-accredited laboratories and satisfies record-keeping provisions of FDA 21 CFR Part 11 when operated with enabled electronic signature and audit trail features (via optional software license).
Software & Data Management
The ZR-5405 includes PC-based calibration management software (Windows 10/11, 64-bit) featuring automated protocol execution per JJF 2051–2023 Annex B. Functions include multi-point ozone span verification, temperature uniformity mapping across chamber zones, and humidity deviation analysis versus setpoint. Raw data files embed metadata (operator ID, chamber ID, ambient conditions, calibration due date) and support digital signature workflows compliant with ALCOA+ principles. Exported reports conform to GLP templates—containing uncertainty budgets (k=2), measurement model equations, and compliance status flags. Data integrity is enforced via SHA-256 hashing of logged records and immutable timestamping synchronized to NTP servers.
Applications
- Periodic calibration and intermediate checks of ozone aging chambers in QC labs serving automotive rubber suppliers (e.g., seals, hoses, bushings).
- Validation of chamber performance prior to ASTM D1149 or ISO 1431-1 conformance testing of vulcanized elastomers.
- Root-cause investigation of premature cracking failures—correlating actual in-chamber O₃ exposure dose (ppm·hr) with specimen degradation kinetics.
- Supporting regulatory submissions requiring documented environmental chamber fidelity (e.g., medical device polymer aging per ISO 10993-12).
- Training and proficiency testing for metrology technicians performing chamber qualification under ISO/IEC 17025 Clause 6.4.
FAQ
Does the ZR-5405 require annual third-party recalibration?
Yes—per JJF 2051–2023 Section 7.2, the system must undergo full functional verification and sensor recalibration at least once per year by an accredited metrology laboratory.
Can it validate ozone concentration gradients inside large-volume chambers?
Yes—when used with optional multi-point extension probes and the chamber mapping module, it supports spatial profiling per ISO 1431-1 Annex C.
Is firmware update capability available over USB or network?
Firmware updates are delivered via encrypted USB stick only; no remote or network-based update functionality is implemented for security and traceability reasons.
What uncertainty budget components are reported in calibration certificates?
Certificates include contributions from sensor nonlinearity, reference standard uncertainty, environmental influence (pressure/temperature), and digital resolution—combined using root-sum-square method per GUM (JCGM 100:2008).
