Product Summary

The PureAire Arsine Fixed Gas Detector is built to continuously monitor arsine gas (AsH₃) and quickly alert you to leaks, even at very low levels. Using a dedicated electrochemical sensor calibrated in parts-per-million (ppm), the detector ensures your fab stays safe and your team is protected from this dangerous gas.

Arsine is widely used in semiconductor fabs during the doping process, especially for creating III-V compound semiconductors like gallium arsenide (GaAs) and indium phosphide (InP). These materials are key for making high-speed chips, LEDs, and solar cells. Arsine is extremely toxic, and since it’s colorless and nearly odorless, you won’t notice a leak without reliable monitoring in place.

PureAire’s arsine sensors are made to last up to 8 years under normal fab conditions and are rechargeable on-site with fresh electrolyte—so you won’t need frequent replacements or long downtimes.

PureAire provides a rugged, easy-to-maintain gas detection solution that keeps your people safe and your production running smoothly for any semiconductor facility using arsine gas.

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 Arsine Fixed 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 arsine gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Arsine 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 arsine 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.

Arsine Gas Detector Low Operation Cost

The PureAire Arsine Gas Detector delivers industry-leading performance with the lowest annual maintenance costs of any fixed gas monitoring system on the market. Unlike expensive disposable sensors, our renewable arsine sensors are field-rechargeable with electrolyte, at just 20% of the cost of traditional sensor replacements. Routine maintenance averages $70 per year, saving your operation hundreds annually while ensuring long-term safety and reliability.

True Stand-Alone Monitoring—Plug in and Protect

Designed for easy, stand-alone operation, PureAire’s Arsine Gas Detector is ready to go right out of the box. Simply mount it near the risk zone, plug it into any 115VAC or 220VAC outlet, and start real-time monitoring with no complicated setup. The detector includes a built-in horn and bright LED alarm indicators that immediately alert staff to dangerous arsine gas levels. Need integration with a broader safety system? No problem. The unit features individual alarm and fault relays, plus an analog 4- 20mA output that easily connects to remote PLC or SCADA systems.

Smart, Self-Monitoring Technology—Peace of Mind 24/7

Behind the scenes, the “smart” electronics of the PureAire Arsine Gas Detector are hard at work 24/7. The system continuously monitors itself for errors, and any fault instantly triggers a signal to your control room via the analog output and fault relay. Maintenance is streamlined too: the sensor’s built-in microcontroller stores calibration data, so you can easily remove it from the transmitter for service, then plug it back in without missing a beat.

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.
