Product Summary

The PureAire Diborane Fixed Gas Detector is an essential safety system for facilities requiring continuous monitoring of diborane (B₂H₆) gas. Designed to work with a dedicated, renewable toxic gas sensor, the detector is calibrated to measure diborane in parts-per billion (ppb) and parts-per-million (ppm), providing accurate and real-time detection of even trace leaks.

Diborane is primarily used in semiconductor manufacturing, photovoltaic cell production, and other high-tech industries, where it serves as a dopant gas in processes like chemical vapor deposition (CVD). Due to its extreme toxicity and flammability, diborane must be carefully controlled and monitored in any facility where it is present.

PureAire’s sensors for diborane offer exceptional longevity—up to 8 years in standard cleanroom or controlled environments. These sensors are rechargeable on-site with electrolyte, which minimizes maintenance downtime and reduces long-term operational costs.

For semiconductor fabs and high-tech facilities working with diborane, PureAire provides a high-performance, low-maintenance gas detection system to safeguard personnel, processes, and infrastructure with confidence and precision.

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 Diborane Gas Detector from PureAire is a compact gas monitor designed to protect workers from exposure to toxic and corrosive gases in the workplace. It consists of a generic transmitter/controller connected to a dedicated, renewable diborane gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Diborane 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 Diborane Gas Detector is the smart, renewable diborane sensor cell programmed with specific 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.

Cost-Effective, Reliable, and Low-Maintenance

Maximize your savings and safety with the PureAire Diborane Gas Detector. Offering the lowest annual maintenance costs of any gas monitoring system on the market, this detector is the perfect choice for companies looking to reduce operational expenses. PureAire’s renewable sensors can be easily recharged in the field with electrolyte at about 20% of the cost of traditional disposable sensors. With routine maintenance costs averaging just $70 per year, you can save hundreds of dollars annually compared to the high-cost alternatives.

Effortless, Stand-Alone Monitoring

The Diborane Gas Detector is designed for seamless, stand-alone operation. Simply mount it to the wall near the risk site, plug it into any 115VAC or 220VAC outlet, and you’re ready to start monitoring right away. The built-in horn and LED alarm indicators ensure that your team is quickly alerted to any hazardous condition, providing peace of mind.

With individual alarm and fault relays, you can easily connect remote alarms or controls for extra flexibility. Plus, the 4-20mA analog output allows for continuous data reporting to remote PLC and SCADA systems, enabling you to monitor conditions from any location.

24/7 Smart Supervision for Maximum Protection

Our Diborane Gas Detector is equipped with advanced “smart” circuitry that provides continuous supervision around the clock. If a system error occurs, the detector’s analog output and fault relay will immediately notify control room personnel, so you can act quickly and prevent potential issues.

The dedicated microcontroller built directly into the sensor allows for easy removal during routine calibration and maintenance. Calibration data is entered directly into the sensor and transferred back to the transmitter once the sensor is reconnected, ensuring optimal performance.

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.
