Product Summary

The PureAire Hydrogen Fixed Gas Detector is designed for continuous monitoring of hydrogen gas (H₂), offering precise detection in environments where safety and process control are paramount. Utilizing a specialized sensor calibrated in parts-per-million (ppm), the system delivers accurate, real-time measurements critical for preventing undetected leaks of this highly flammable gas.

Hydrogen plays a key role in scientific research, fuel cell development, chemical processing, semiconductor fabrication, and advanced energy systems. Due to its low ignition energy, rapid diffusion rate, and broad flammability range, hydrogen presents a unique safety challenge in confined or sensitive environments such as laboratories, R&D facilities, and cleanrooms.

PureAire’s hydrogen sensors are engineered to last up to 8 years in standard operating conditions. They are also rechargeable on-site with a fresh electrolyte, supporting ongoing safety without the need for frequent sensor replacement or calibration downtime.

For research institutions, hydrogen storage facilities, and high-tech manufacturers, PureAire offers a scientifically robust and maintenance-friendly gas detection system to help mitigate risk, support compliance, and ensure continuous operational integrity where hydrogen is in use.

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 Fixed 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 connected to a dedicated, renewable hydrogen gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the PureAire Hydrogen Fixed 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 sensor cell programmed with specific gas and measurement range information. Simply plug the sensor into any Universal Gas Detector transmitter, and it’s ready to go. When servicing the sensors, they can be recharged with fresh electrolyte and dynamically gas-calibrated in the maintenance shop away from the transmitter.

Save Big on Annual Maintenance—Without Compromising Safety

Looking to cut down on operating costs without sacrificing performance? The PureAire Hydrogen Fixed Gas Detector is one of the most cost-effective hydrogen monitoring solutions available today. It features renewable sensor technology that allows you to recharge the sensor right in the field using fresh electrolyte, eliminating the need for expensive disposable cells. This process costs only about 20% of traditional sensor replacements, and with annual maintenance materials averaging  $70, you’ll save hundreds of dollars every year.

Quick Setup, Stand-Alone Operation

This detector was designed for simplicity and reliability. You can mount it directly near any hydrogen risk zone and plug it into a standard 115VAC or 220VAC power source—no controllers or network systems required. Once powered, it immediately begins monitoring the area. If hydrogen gas is detected, a built-in alarm horn and bright LED indicators provide instant, on-site alerts to keep personnel safe. It also includes individual alarm and fault relays for remote signaling, and a 4–20mA analog output for real-time data transmission to SCADA or PLC systems.

24/7 Smart Supervision You Can Trust

With its intelligent electronics, the Hydrogen Fixed Gas Detector keeps itself in check around the clock. The system is constantly self-supervised, and if a malfunction occurs, the analog output and fault relay immediately notify your control room, ensuring rapid response. A dedicated microcontroller built into the sensor allows it to store and manage calibration data independently. You can remove the sensor for maintenance or calibration, and once it’s plugged back in, all settings and data are automatically transferred to the transmitter, keeping downtime to a minimum and accuracy at a maximum.

Engineered for Safety – Built for Value

From manufacturing and energy storage facilities to research labs and industrial plants, the PureAire Hydrogen Fixed Gas Detector delivers long-lasting performance, minimal maintenance, and maximum peace of mind.
