Description
The PureAire Universal Hydrogen Fluoride (HF) Gas Detector is a fixed gas monitoring system designed for continuous hydrogen fluoride detection in semiconductor manufacturing, glass etching, chemical processing, petroleum refining, laboratories, and other locations where hydrogen fluoride gas may be present.
This Hydrogen Fluoride Gas Detector is available in 0–9 ppm and 0–30 ppm detection ranges, allowing the appropriate measurement range to be selected for the application. The PureAire Universal Gas Detector provides continuous, real-time hydrogen fluoride monitoring for facility and personnel safety applications.
The monitor features a local digital display, built-in audible alarm, visual alarm indicators, two adjustable alarm relays, and an active 4–20 mA output for integration with PLCs, facility monitoring systems, ventilation equipment, remote alarms, and other safety systems.
Because hydrogen fluoride can present a hazard at elevated concentrations, continuous fixed monitoring with local alarms and 4–20 mA integration can provide early warning as concentrations increase.

Hydrogen Fluoride Safety Monitoring
Hydrogen fluoride is a highly toxic and corrosive gas that poses a serious health hazard even at low concentrations. Continuous fixed monitoring can be used with ventilation, alarm, and facility control systems to provide early warning of increasing hydrogen fluoride concentrations.
System Integration
The active 4–20 mA output and adjustable alarm relays allow the detector to interface with PLCs, ventilation equipment, external horns and strobes, remote displays, and other facility safety systems when properly configured.

The PureAire Universal Hydrogen Fluoride Gas Detector is designed for continuous HF monitoring in areas where hydrogen fluoride is used, stored, handled, or may be released.
Typical Applications
- Semiconductor manufacturing
- Glass etching and processing
- Chemical processing facilities
- Petroleum refining
- Laboratories and research facilities
- Gas cabinets and distribution systems
- Industrial manufacturing
- Workplace safety monitoring
Detector placement should account for potential release points and airflow patterns in the monitored area. Final detector location, alarm settings, ventilation requirements, and system integration should be based on the specific application and applicable safety requirements.
