Boron Trifluoride Gas Detector

$2,170.00

Product Summary

The PureAire Boron Trifluoride Fixed Gas Detector is a dependable solution for facilities that require continuous monitoring of boron trifluoride (BF₃) gas. Designed to pair with a dedicated, renewable toxic gas sensor, the system is calibrated to detect BF₃ in parts-per-million (ppm), ensuring accurate, real-time protection against hazardous leaks.

This detector is particularly suited for use in chemical processing, semiconductor manufacturing, polymerization reactions, and specialty gas production, where boron trifluoride is commonly used as a strong Lewis acid catalyst. Due to its high toxicity and corrosiveness—especially when it reacts with moisture to form hydrofluoric acid—a continuous gas detection system is critical for maintaining a safe work environment.

PureAire’s BF₃ sensors are engineered for extended service life—lasting up to 8 years in typical process environments. They are also user-rechargeable on-site with electrolyte, minimizing downtime and reducing overall maintenance costs.

For industries handling boron trifluoride, PureAire provides a robust, accurate, and low-maintenance gas detection system to help ensure operational safety and compliance.

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.

PureAire’s Boron Trifluoride Gas Detector is a fixed, 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 trifluoride gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Boron Trifluoride 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 Trifluoride Gas Detector is the smart, renewable 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

Save more, protect more with the PureAire Boron Trifluoride Gas Detector, which offers the lowest annual maintenance costs of any gas monitoring system available today. Our renewable boron trifluoride sensors are designed for easy electrolyte recharge in the field, reducing maintenance costs to only 20% of the price of traditional disposable sensors. With an average of just $70 in routine maintenance each year, you can save hundreds of dollars annually compared to costly disposable sensor systems!

Seamless, Stand-Alone Monitoring

The PureAire Boron Trifluoride Gas Detector is built for ease of use and reliability. Simply mount the device near the potential risk area, plug it into a 115VAC or 220VAC outlet, and you’re ready to start monitoring. The built-in horn and LED alarm indicators provide immediate warnings, alerting your team to any hazardous conditions.

The system also includes alarm and fault relays for remote connections and control, and the 4–20mA analog output ensures continuous, real-time data integration with remote PLC and SCADA systems, keeping your operations running smoothly and efficiently.

Smart Supervision for Uninterrupted Monitoring

With its advanced “smart” circuitry, the Boron Trifluoride Gas Detector is continuously supervised 24/7. Should any system malfunction arise, the analog output and fault relay will immediately notify control room personnel, allowing for rapid intervention.

Additionally, a dedicated microcontroller integrated directly into the sensor enables easy removal for routine calibration and maintenance. Calibration data is entered directly into the sensor and automatically transferred to the transmitter once plugged back in, ensuring minimal downtime and continuous protection.
