Aeroqual O3 GSS 0–0.15 ppm — Ozone Sensor for Ultra‑Low Concentrations

Unlock precise ozone monitoring where every part per billion matters with the Aeroqual O3 GSS 0–0.15 ppm sensor head. Built on Gas Sensitive Semiconductor (GSS) technology and tuned for ultra‑low ozone concentrations, it delivers stable, fast, and repeatable readings in indoor and ambient environments. Designed as a plug‑in head for Aeroqual portable and fixed monitors, it helps laboratories, cleanrooms, IAQ professionals, and industrial hygienists move from spot checks to confident decision‑making with ppb‑level resolution and dependable baseline stability. Available from Stratosens.com with expert guidance and after‑sales support.

Key Benefits and Applications

• Measure ultra‑low ozone accurately — Purpose‑built 0–0.15 ppm range captures background and indoor levels with clarity, ideal for air quality studies, workplace exposure assessments, museums, hospitals, and clean manufacturing.
• Fast, stable readings — Rapid response and excellent baseline stability support real‑time optimisation of ventilation, filtration, and process controls.
• Plug‑and‑play integration — Quick‑swap sensor head design works seamlessly with compatible Aeroqual handheld and fixed platforms, reducing downtime and simplifying fleet management.
• Lower cost of ownership — Long service life with field zero and span adjustment options helps extend calibration intervals and control total monitoring costs.
• Confidence for audits and research — Factory calibration to traceable standards and high repeatability provide consistent data for trend analysis and reporting against internal or external guidelines.
• Compact and robust — Lightweight form factor enables discreet deployment on carts, tripods, or wall mounts without compromising measurement quality.

Featured technical specifications

• Measurement range — 0 to 0.15 ppm for high resolution monitoring of indoor and ambient ozone. Approximate equivalent 0 to 0.29 mg·m⁻³ at 25 °C and 101.3 kPa.
