Product Summary

The PureAire Boron Trichloride Fixed Gas Detector is a reliable and essential safety solution for facilities that require continuous monitoring of boron trichloride (BCl₃) gas. Engineered to connect with a dedicated, renewable toxic gas sensor, the system is calibrated to detect boron trichloride in parts-per-million (ppm), providing dependable, real-time data to protect personnel and equipment.

This detector is especially critical in semiconductor fabrication, plasma etching processes, specialty chemical manufacturing, and metal refining operations, where BCl₃ is commonly used for its reactive properties. Because boron trichloride is highly toxic and corrosive—especially when it contacts moisture—robust gas detection is vital for ensuring safe operations and regulatory compliance.

PureAire’s sensors for boron trichloride are designed to last up to 8 years in standard industrial settings. These sensors are rechargeable on-site with electrolyte, allowing for simple maintenance and reducing long-term ownership costs.

For any operation involving BCl₃, PureAire offers a durable, low-maintenance gas detection solution that safeguards both people and processes with precision and reliability.

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 Boron Trichloride 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 boron trichloride gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the PureAire Boron Trichloride 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 Boron Trichloride Gas Detector is the smart, renewable boron trichloride 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 Operation Cost– Affordable & Reliable

Protect your people, property, and processes with the PureAire Boron Trichloride Fixed Gas Detector — the smart, cost-effective solution for continuous hazardous gas monitoring.

Lowest Total Cost of Ownership in the Industry. PureAire’s renewable sensor technology slashes maintenance costs, allowing you to recharge sensors in the field for just a fraction of the price of disposable alternatives — about 20% of the cost. With routine upkeep averaging just $70 per year, you’ll save hundreds of dollars annually on service without sacrificing performance.

Plug-and-Protect Stand-Alone Monitoring

Forget complicated installation. The PureAire Boron Trichloride Detector is designed for true stand-alone operation. Simply mount it near the hazard zone, plug into a standard 115VAC or 220VAC outlet, and you’re up and running in minutes.

Equipped with a built-in horn and bright LED indicators, the system provides instant on-site alerts. Plus, with dedicated alarm and fault relays and a 4–20mA output, it easily integrates with PLC and SCADA systems for centralized monitoring and control.

Smart, Self-Supervising Safety

Stay protected 24/7 with advanced smart diagnostics. The detector’s onboard microcontroller continuously supervises the system’s performance — if a fault occurs, the analog output and fault relay instantly signal your control room. No guessing. No delays. Routine maintenance is quick and convenient. The sensor can be detached for calibration, with data automatically synced back to the transmitter when reconnected, saving you time and ensuring accuracy.

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.
