Product Summary

The PureAire Hydrogen Peroxide Fixed Gas Detector offers accurate, around-the-clock monitoring of hydrogen peroxide (Hâ‚‚Oâ‚‚) vapor. Paired with a dedicated electrochemical sensor calibrated in parts-per-million (ppm), the system provides real-time detection to help ensure safe conditions in environments where hydrogen peroxide is used or stored.

Hydrogen peroxide is commonly used in semiconductor manufacturing, cleanroom sterilization, and advanced surface cleaning applications. It’s also present in pharmaceutical, aerospace, and biotechnology sectors for high-purity cleaning and disinfection processes. While highly effective, H₂O₂ can become hazardous at elevated concentrations—posing risks of irritation, corrosion, and chemical exposure—making continuous monitoring essential in high-tech workspaces.

PureAire’s sensors for hydrogen peroxide are engineered for long life—lasting up to 8 years—and are user-rechargeable with on-site electrolyte, keeping maintenance simple and cost-efficient.

For clean manufacturing environments and high-purity applications, PureAire delivers a dependable, low-maintenance hydrogen peroxide detection system to safeguard workers, support compliance, and protect critical production processes.

Please note that because of the nature of this product, the lead time is typically 2-3 days but may be up to one week. We will make every effort to ship your order as soon as possible.

The PureAire Hydrogen Peroxide 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, hydrogen peroxide gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Hydrogen Peroxide 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 Hydrogen Peroxide Gas Detector is a smart, renewable, hydrogen peroxide 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.

Low Annual Operating Costs

Looking for a cost-effective solution to monitor Hydrogen Peroxide? Look no further than the PureAire Hydrogen Peroxide Gas Detector, the most affordable gas monitoring system when it comes to maintenance costs. PureAire’s renewable sensors can be easily recharged with electrolyte on-site, at just 20% of the cost of disposable sensor cells. Routine maintenance averages $70 per year, so you’ll save hundreds of dollars annually compared to the expensive disposable sensor alternatives. Why pay more when you can have high performance at a fraction of the cost?

Effortless Stand-Alone Operation

Designed for ultimate convenience, the PureAire Hydrogen Peroxide Gas Detector operates completely stand-alone. Simply mount the unit to the wall near the potential risk zone, plug it into any standard 115VAC 60 Hz or 220VAC 50 Hz outlet, and you’re ready to start monitoring hydrogen peroxide levels in no time. It’s that easy! The built-in horn and LED alarm indicators ensure rapid alerts in case of a hazardous condition, keeping your team safe. Plus, you can easily integrate individual alarm and fault relays with remote alarms or control systems. The 4-20mA analog output also provides continuous data to remote PLC and SCADA systems, offering seamless integration with your existing infrastructure.

Smart, 24/7 Supervision

The PureAire Hydrogen Peroxide Gas Detector features intelligent circuitry that is supervised 24/7, ensuring your system is always working properly. In case of a system malfunction, the detector’s analog output and fault relay immediately notify control room personnel, minimizing downtime and risk. Maintenance is a breeze with its dedicated microcontroller built right into the sensor, allowing you to easily remove it from the transmitter for routine calibration and maintenance. Calibration data is directly entered into the sensor and seamlessly transferred to the transmitter once plugged back in, ensuring consistent and accurate monitoring.

Save on costs, improve safety, and reduce hassle with PureAire’s Hydrogen Peroxide Gas Detector—the smart, cost-efficient choice for reliable gas detection!

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.
