HUANKONG GHK-100 Portable Ozone Analyzer

Overview

The HUANKONG GHK-100 Portable Ozone Analyzer is a field-deployable, UV photometric gas analyzer engineered for precise, real-time measurement of ambient ozone (O₃) concentration in air. It operates on the principle of ultraviolet absorption spectroscopy at 254 nm—the characteristic absorption peak of ozone—ensuring high selectivity and minimal cross-sensitivity to common atmospheric interferents such as NO₂, SO₂, and VOCs. Designed for compliance with internationally recognized analytical methodologies—including HJ 590–2010 (Chinese standard equivalent to ISO 13964:2021 and EPA Method IO-3)—the GHK-100 delivers laboratory-grade accuracy in a rugged, handheld platform. Its compact architecture integrates a low-power, long-life UV optical module with temperature-stabilized detection optics, eliminating warm-up delays and enabling immediate start-up measurements under variable environmental conditions.

Key Features

• UV photometric detection at 254 nm with dual-beam optical design for enhanced stability and drift compensation
• Portable form factor (≤2.8 kg) with foldable ergonomic handle and aerospace-grade magnesium-aluminum alloy enclosure (IP54 ingress protection)
• 5-inch capacitive touchscreen interface with intuitive navigation, real-time waveform display, and on-device data review
• Integrated dual-mode positioning: BeiDou + GPS modules for geotagged measurement logging and spatial traceability
• Onboard 8 GB internal storage supporting timestamped, audit-ready data logs (CSV format), exportable via USB or Bluetooth thermal printer
• Rechargeable high-capacity lithium-ion battery providing ≥12 h continuous operation at 25°C; supports hot-swappable battery option for extended field missions
• Low-maintenance design: replaceable particulate filter (recommended every 3–5 days in high-dust environments) and hydrophobic membrane filter (replaced semiannually); no optical alignment or calibration gas required during routine use

Sample Compatibility & Compliance

The GHK-100 is validated for direct analysis of ambient air, indoor air, and workplace breathing-zone samples without pre-concentration or chemical conversion. It meets the performance criteria specified in HJ 654–2013 for continuous ambient air monitoring systems and satisfies metrological requirements outlined in JJG 1077–2012 (Ozone Gas Analyzer Verification Regulation). Data integrity aligns with GLP principles: each measurement record includes instrument ID, GPS coordinates, UTC timestamp, ambient temperature/pressure/humidity (via integrated sensors), and diagnostic flags (e.g., lamp intensity, flow rate, optical path status). The analyzer is compatible with national indoor air quality assessment per GB/T 18883–2022 and supports regulatory reporting frameworks for occupational exposure limit (OEL) verification (e.g., OSHA PEL, ACGIH TLV).

Software & Data Management

The GHK-100 interfaces seamlessly with the HUANKONG Cloud Terminal Data Management System via embedded 4G LTE (Cat-M1) or Wi-Fi 802.11n connectivity. All measurement data—including raw absorbance values, calculated O₃ concentration, diagnostics, and metadata—are encrypted (AES-256) and transmitted in near real time. The cloud platform provides role-based access control, automated report generation (daily/weekly/monthly), configurable alarm thresholds (SMS/email notifications), and historical trend visualization with overlay capability for multi-instrument deployments. Audit trails comply with FDA 21 CFR Part 11 requirements for electronic records and signatures, including user login history, data modification logs, and electronic signature capture for validation reports.

Applications

• Emergency response monitoring during industrial incidents or photochemical smog events
• Mobile air quality mapping from vehicle-mounted or bicycle-mounted platforms
• Roadside ambient monitoring along highways and urban corridors
• Occupational hygiene assessments in water treatment facilities, semiconductor cleanrooms, and disinfection units
• Indoor air quality surveys in schools, hospitals, and office buildings
• Calibration verification and QA/QC support for fixed-site ozone monitoring networks

FAQ

What is the measurement principle used in the GHK-100?

It employs UV absorption photometry at 254 nm, based on the Beer–Lambert law, with a reference beam for real-time compensation of lamp aging and optical fouling.
Does the instrument require zero/span calibration in the field?

No routine zero/span calibration is needed; however, optional automated zero checks using internal synthetic air purge are available via software configuration.
Can the GHK-100 operate in high-humidity environments?

Yes—it incorporates a Nafion™-based humidity management system upstream of the optical cell to maintain dew point below –20°C, preventing condensation-induced signal attenuation.
Is the device certified for use in explosion-hazardous areas?

Not intrinsically safe (ATEX/IECEx); it is rated for general-purpose outdoor and indoor use only.
How is data security ensured during wireless transmission?

All telemetry uses TLS 1.2 encryption, device authentication via X.509 certificates, and session key rotation; local storage is encrypted at rest.
