The PureAire Ammonia 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/controller connected to a dedicated, renewable ammonia gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Ammonia 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 ammonia 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.
Ultra-Low Annual Maintenance Costs
The PureAire Ammonia Fixed Gas Detector offers one of the most cost-effective solutions on the market, delivering powerful gas detection performance with minimal maintenance expenses. Unlike systems that rely on expensive disposable sensors, PureAire’s renewable ammonia sensors can be easily recharged with fresh electrolyte right in the field. This simple process costs just a fraction—about 20%—of what you’d spend replacing traditional sensor cells. With routine maintenance materials averaging $70 per year, businesses can save hundreds annually while ensuring reliable, continuous ammonia monitoring.
Effortless, Stand-Alone Monitoring
Designed for true stand-alone operation, the PureAire detector is incredibly easy to install and use. Simply mount it near the ammonia risk area, plug it into a standard 115VAC or 220VAC outlet, and the system is ready to monitor. The unit includes a built-in horn and bright LED alarm indicators that immediately alert personnel to the presence of hazardous gas levels. For added flexibility, the detector features individual alarm and fault relays for connecting to remote alarms or control systems, while the 4–20mA analog output ensures seamless communication with PLC and SCADA systems.
24/7 Smart Monitoring Technology
Engineered with advanced smart technology, the PureAire detector continuously supervises its internal electronics 24/7. If a system error occurs, it instantly triggers alerts through both its analog output and fault relay, notifying your control room of the issue in real time. A dedicated microcontroller is built directly into the sensor, allowing it to be removed for routine calibration or maintenance without interrupting system integrity. Once reconnected, the sensor automatically transfers stored calibration data back to the transmitter for a quick, hassle-free return to operation.
