Product Summary

The PureAire Fluorine Fixed Gas Detector is engineered for continuous monitoring of fluorine gas (F₂), a highly reactive and toxic oxidizer used in advanced industrial processes. Equipped with a dedicated electrochemical sensor calibrated in parts-per-million (ppm), the system provides accurate, real-time detection to help maintain a safe atmosphere in critical environments where fluorine is present.

Fluorine is commonly used in semiconductor manufacturing, chemical processing, and excimer laser systems, which are essential for applications like microchip fabrication, wafer etching, and surface treatment. Because fluorine is both corrosive and harmful to inhale, it’s crucial to monitor air quality constantly to prevent accidents and equipment damage.

The detector includes a long-life sensor that lasts up to 8 years under normal conditions and is easily recharged on-site with electrolyte, keeping maintenance simple and downtime low.

Whether you’re working with high-tech lasers, precision electronics, or specialty gases, PureAire’s fluorine gas detector offers a dependable, low-maintenance safety solution to help you stay protected and compliant.

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 Fluorine Gas Detector is a compact 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 fluorine gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Fluorine 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 Fluorine Gas Detector is the smart, renewable fluorine 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.

Maximum Savings, Maximum Safety

Cost-effective, reliable, and easy-to-maintain, the PureAire Fluorine Gas Detector offers the lowest annual operating costs of any gas monitoring system on the market. Our renewable fluorine sensors can be recharged with electrolyte right in the field, saving you up to 80% compared to expensive disposable sensors. With average routine maintenance costs of just $70/year, you’ll enjoy significant savings while ensuring continuous protection for your site.

Hassle-Free, Stand-Alone Monitoring

The PureAire Fluorine Gas Detector is designed for easy, stand-alone operation. Simply mount it to the wall near the risk area, plug it into any 115VAC or 220VAC outlet, and start monitoring immediately. The built-in horn and LED alarm indicators provide instant alerts, notifying your team of any hazardous conditions.

It also features individual alarm and fault relays, allowing you to connect remote alarms or controls for added flexibility. Plus, the 4-20mA analog output continuously streams real-time data to remote PLC and SCADA systems, providing seamless integration into your overall safety infrastructure.

24/7 Smart Monitoring

With its advanced “smart” circuitry, the Fluorine Gas Detector provides continuous, 24/7 supervision. Should a system error occur, the analog output and fault relay immediately notify your control room, ensuring swift action. The dedicated microcontroller built into the sensor allows for easy calibration and maintenance—simply remove the sensor, enter calibration data directly into the electronics, and then plug it back into the transmitter for seamless operation.

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.
