Product Summary

The PureAire Hydrogen Cyanide Fixed Gas Detector provides continuous, high-precision monitoring of hydrogen cyanide (HCN) gas, utilizing a dedicated electrochemical sensor calibrated in parts-per-million (ppm). This system offers real-time detection critical to maintaining safe working conditions in environments where HCN is present—even in trace amounts.

Hydrogen cyanide is used in semiconductor manufacturing, particularly in metal extraction, surface treatment, and advanced materials processing. While effective in these applications, HCN is extremely toxic, with exposure risks at very low concentrations. Continuous monitoring is essential in cleanroom environments to protect workers and maintain control over delicate fabrication processes.

PureAire’s HCN sensors are engineered for long-term reliability—lasting up to 8 years in standard conditions—and are user-rechargeable with on-site electrolyte replacement, minimizing downtime and simplifying maintenance routines.

For high-tech industries using hydrogen cyanide, PureAire delivers a robust, low-maintenance detection system that supports operational safety, compliance, and precision in sensitive semiconductor environments.

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 Cyanide Gas Detector is a fixed 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 cyanide gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Hydrogen Cyanide 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 Hydrogen Cyanide Gas Detector is a smart, renewable sensor cell programmed with hydrogen cyanide 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.

Cut Costs Without Compromising Safety

When it comes to reliable gas detection, the PureAire Hydrogen Cyanide Gas Detector stands out—not just for its performance, but for its unbeatable low annual operating cost. Unlike disposable sensors that require frequent, expensive replacements, PureAire’s renewable sensors are field-rechargeable with electrolyte, slashing maintenance costs to just 20% of traditional disposable systems. With annual upkeep averaging only $70, you’ll save hundreds of dollars every year—all while maintaining high-level safety monitoring.

Plug-and-Play Stand-Alone Monitoring

Installation is effortless. The Hydrogen Cyanide Gas Detector is a fully stand-alone unit—just mount it near your risk zone and plug it into any 115VAC or 220VAC outlet. Immediately start monitoring with no complicated wiring or configuration. A built-in horn and bright LED alarms provide instant alerts to keep your personnel safe. Plus, the unit includes dedicated alarm and fault relays for integrating with remote alarms or control systems, and a 4- 20mA analog output to feed continuous, real-time data directly into your PLC or SCADA system.

Smart, Always-On Supervision

Stay ahead of problems with 24/7 intelligent monitoring. PureAire’s advanced “smart” circuitry constantly checks system performance, instantly signaling any issues through its fault relay and analog output. Maintenance is simple, thanks to a dedicated microcontroller inside the sensor that stores calibration data. Remove the sensor for routine service, plug it back in, and it picks up exactly where it left off, with no extra programming or recalibration needed.

Smart. Safe. Cost-Effective.
Choose PureAire’s Hydrogen Cyanide Gas Detector and experience worry-free performance with long-term savings.
