Product Summary

The PureAire Ozone Fixed Gas Detector is designed for continuous, real-time monitoring of ozone (O₃) gas, providing accurate detection in environments where ozone is used for sanitation, oxidation, or disinfection. The system features a dedicated electrochemical sensor calibrated in parts-per-million (ppm), delivering fast, reliable alerts when ozone levels become unsafe.

Ozone is widely used in water and wastewater treatment, where it serves as a powerful oxidizer for disinfection, odor control, and organic contaminant breakdown. It’s also used in food processing, pharmaceutical manufacturing, and air purification systems. While highly effective, ozone is toxic at low concentrations, causing irritation to the lungs, eyes, and throat, making continuous monitoring vital in enclosed or poorly ventilated areas.

PureAire’s ozone sensors are built for long-lasting use—up to 8 years under typical conditions—and are easily rechargeable on-site with electrolyte, minimizing downtime and reducing maintenance costs.

For water treatment plants and industrial facilities using ozone, PureAire provides a dependable, low-maintenance gas detection system that helps ensure worker safety, regulatory compliance, and consistent process performance.

The PureAire Ozone Fixed Gas Detector is a compact fixed gas monitor that’s ideal for protecting workers from toxic and corrosive gas exposure in the workplace. It consists of a transmitter/controller connected to a dedicated, renewable Ozone gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Ozone Fixed Gas Detector can also be connected to any programmable logic controller or SCADA system. PureAire also manufactures toxic gas detectors with a remote sensor. 

The heart of the system is a smart, renewable Ozone sensor cell programmed with gas and measurement range information. When servicing the sensors, they can be recharged with fresh electrolyte and dynamically gas-calibrated in the maintenance shop away from the transmitter.

Cut Costs Without Compromising Safety

The PureAire Ozone Gas Detector delivers powerful protection against ozone leaks, without the high maintenance costs typical of other gas detection systems. Unlike disposable sensor models, PureAire’s advanced renewable ozone sensors can be recharged with fresh electrolyte right in the field, reducing replacement costs to just 20% of conventional systems. With routine upkeep materials averaging $70 per year, you’ll save hundreds of dollars annually while keeping your team and facility safe.

True Stand-Alone Performance—Fast Setup, Instant Monitoring

No need for complex wiring or external control systems. The PureAire Ozone Gas Detector is a fully self-contained monitoring solution. Simply mount it near the hazard area, plug it into any standard 115VAC or 220VAC outlet, and you’re ready to monitor. The unit features a built-in horn and ultra-bright LED alarms that instantly notify personnel of dangerous conditions. For broader safety integration, it also includes dedicated alarm and fault relays, and a 4–20mA analog output for real-time data transmission to PLC and SCADA systems.

Smart, Self-Monitoring Technology

Backed by 24/7 electronic supervision, the Ozone Gas Detector continuously monitors both environmental conditions and its own internal performance. If a system issue arises, it will immediately trigger alerts via the analog output and fault relay. A built-in microcontroller inside the sensor stores calibration data, enabling the sensor to be easily removed, serviced, and reinstalled, with no manual data entry or reprogramming needed. The system automatically syncs, keeping your safety uninterrupted.

Reliable Protection. Simple Maintenance. Long-Term Value.

Whether you’re safeguarding a research lab, industrial facility, or cleanroom, the PureAire Ozone Gas Detector is the smart choice for cost-effective, continuous gas monitoring. With low ownership costs, plug-and-play setup, and intelligent self-supervision, this detector is built for performance and savings.

A toxic gas detector continuously monitors the air for harmful gases, including carbon monoxide, chlorine, ammonia, and hydrogen sulfide. It warns personnel before levels reach dangerous concentrations. Toxic gas detectors protect workers from low-level poisonous gases (in the ppm range) that can cause immediate or long-term health effects.

The most common include:
• Carbon monoxide (CO) – parking garages, boiler rooms
• Hydrogen sulfide (H₂S) – oil & gas, wastewater treatment
• Chlorine (Cl₂) – water treatment, chemical plants
• Ammonia (NH₃) – refrigeration, food processing
• Nitrogen dioxide (NO₂) – vehicle maintenance facilities
• Sulfur dioxide (SO₂) – power plants, refineries
• Ozone (O₃) – semiconductor, pharmaceutical industries
• Refrigerant gases (classified as A1, A2L, B2L, A3) – HVAC systems, supermarkets, cold storage, data centers

• Electrochemical sensors: Accurate, low-level detection; best for most toxic gases (CO, H₂S, Cl₂, NH₃).
• PID (Photoionization Detectors): Detects volatile organic compounds (VOCs) and low-level hydrocarbons.
• NDIR (Non-Dispersive Infrared): Used more often for CO₂ or gases that absorb infrared light. NDIR sensor cells are highly effective for detecting refrigerant gases across classifications A1, A2L, B2L, and A3.

• CO: 0–100 ppm, 0–1,000 ppm
• H₂S: 0–30 ppm, 0–200 ppm
• Cl₂: 0–1 ppm, 0–3 ppm, 0–10 ppm, 0–50 ppm, 0–200 ppm
• NH₃: 0–75 ppm, 0–100 ppm, 0–200 ppm, 0–300 ppm, 0–1,000 ppm
• NO₂: 0–2 ppm, 0–9 ppm, 0–15 ppm, 0–20 ppm
• SO₂: 0–15 ppm, 0–20 ppm
• O₃: 0–0.3 ppm, 0–1 ppm, 0–3 ppm, 0–300 ppm
• Refrigerant gases (A1, A2L, B2L, A3 classifications): 0–500 ppm, 0–1,000 ppm, 0–5,000 ppm

• Oil & gas: H₂S monitoring in drilling and refining
• Water/wastewater treatment: Chlorine and H₂S detection
• Food & beverage: Ammonia refrigeration monitoring
• Laboratories & pharma: VOC and toxic gas detection
• Manufacturing & automotive: CO and NO₂ monitoring
• Power generation: SO₂ monitoring in flue gas areas
• HVAC, supermarkets, cold storage & data centers: Refrigerant leak monitoring (A1, A2L, B2L, A3 gas classifications)

Consider:
• The specific gas hazards in your facility
• Sensor type (electrochemical, PID, NDIR, etc.) based on gas and concentration range
• Installation environment (indoor, outdoor, temperature/humidity conditions)
• Compliance needs (OSHA, IFC, local codes)
• Integration with alarms, PLCs, or cloud monitoring systems like PureAire’s CloudConnect

• Electrochemical sensors: Every 6–12 months
• PID sensors: Every 3–6 months
Always follow the manufacturer’s recommendation and perform bump tests for safety.

• LEL: Percentage of gas concentration at which ignition becomes possible. Combustible detectors typically measure 0–100% LEL.
• PPM (parts per million): A finer measurement, usually used for toxic gases rather than combustibles.

Yes, in most cases. Some gases, such as hydrogen sulfide (H₂S), carbon monoxide (CO), and ammonia (NH₃), pose toxic risks at very low concentrations (ppm levels) and combustible risks at higher concentrations (% LEL).
• A toxic gas detector is needed to protect worker health by alarming at ppm exposure limits set by OSHA and other agencies.
• A combustible gas detector is needed to prevent explosions or fires when gas levels approach the Lower Explosive Limit (LEL).

Since the alarm thresholds and sensor technologies differ, a single detector usually cannot provide both types of protection. Many facilities use both toxic and combustible gas detectors for full coverage, often integrated into a single safety system.  This system can activate building ventilation and advanced warning systems when gas levels reach dangerous concentrations.

If a gas is toxic at low ppm and combustible at higher % LEL, you may need dual detection — one detector set for ppm exposure, another for explosion hazard. Sensor selection depends on whether the primary risk is worker health, explosion, or both.
