Hydrogen Fluoride Gas Detector

$2,170.00

Product Summary

The PureAire Hydrogen Fluoride Fixed Gas Detector is designed for continuous, real-time monitoring of hydrogen fluoride (HF) gas. Equipped with a dedicated electrochemical sensor calibrated in parts-per-million (ppm), the detector ensures precise and reliable detection of HF leaks in critical environments where safety and system integrity are essential.

Hydrogen fluoride is widely used in semiconductor manufacturing, especially in etching silicon wafers, glass treatment, and cleaning processes. HF is extremely corrosive and toxic, capable of penetrating skin and causing severe chemical burns—even at low concentrations. In cleanrooms and advanced manufacturing environments, accurate gas detection is vital to protect personnel and sensitive equipment.

PureAire’s HF sensors are engineered for extended service life—up to 8 years under typical cleanroom or industrial conditions. They are also user-rechargeable with on-site electrolyte replacement, reducing maintenance effort and operational downtime.

For semiconductor fabs, laboratories, and precision manufacturing facilities, PureAire provides a durable, low-maintenance hydrogen fluoride gas detection system that supports safety, compliance, and process control without compromise.

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 Hydrogen Fluoride 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 hydrogen fluoride gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Hydrogen Fluoride 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 hydrogen fluoride 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 Safety, Minimal Maintenance Costs

Monitoring hazardous gases doesn’t have to come with high upkeep. The PureAire Hydrogen Fluoride Gas Detector is engineered for long-term performance with the lowest annual maintenance costs in the industry. Thanks to PureAire’s renewable sensor technology, you can easily recharge the hydrogen fluoride sensor in the field, at just 20% of the cost of disposable sensor systems. With routine maintenance supplies averaging $70 per year, this detector offers dependable protection that saves you hundreds of dollars annually.

Plug-and-Play Simplicity

Designed to operate as a fully stand-alone system, the Hydrogen Fluoride Gas Detector is ready to go right out of the box. Just mount it near the hazard zone, plug it into a standard 115VAC or 220VAC outlet, and start monitoring immediately. A built-in horn and bright LED indicators provide instant alerts in the event of a leak. For added flexibility, the unit includes alarm and fault relays for remote notifications, as well as a 4–20mA analog output for seamless integration with your PLC or SCADA systems.

Smart Monitoring That Watches Itself—24/7

This detector doesn’t just protect your space—it protects itself. Featuring around-the-clock self-supervised electronics, the system will automatically alert your control room if anything goes wrong using both analog output and fault relays. A dedicated microcontroller inside the sensor stores all calibration data, allowing for easy removal and service. Once reinstalled, the sensor automatically syncs with the transmitter—no reconfiguration needed.

Built for Safety. Priced for Savings. Trusted for Performance.

The PureAire Hydrogen Fluoride Gas Detector delivers everything safety managers need: low maintenance, high reliability, and seamless operation—all at an industry-leading cost of ownership. Whether you’re safeguarding a lab, a manufacturing floor, or a chemical process environment, it’s the smart solution that pays for itself year after year.
