Arsine Gas Detector

$2,170.00

Product Summary

The PureAire Arsine Fixed Gas Detector is built to continuously monitor arsine gas (AsH₃) and quickly alert you to leaks, even at very low levels. Using a dedicated electrochemical sensor calibrated in parts-per-million (ppm), the detector ensures your fab stays safe and your team is protected from this dangerous gas.

Arsine is widely used in semiconductor fabs during the doping process, especially for creating III-V compound semiconductors like gallium arsenide (GaAs) and indium phosphide (InP). These materials are key for making high-speed chips, LEDs, and solar cells. Arsine is extremely toxic, and since it’s colorless and nearly odorless, you won’t notice a leak without reliable monitoring in place.

PureAire’s arsine sensors are made to last up to 8 years under normal fab conditions and are rechargeable on-site with fresh electrolyte—so you won’t need frequent replacements or long downtimes.

PureAire provides a rugged, easy-to-maintain gas detection solution that keeps your people safe and your production running smoothly for any semiconductor facility using arsine gas.

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 Arsine 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 arsine gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Arsine 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 arsine 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.

Arsine Gas Detector Low Operation Cost

The PureAire Arsine Gas Detector delivers industry-leading performance with the lowest annual maintenance costs of any fixed gas monitoring system on the market. Unlike expensive disposable sensors, our renewable arsine sensors are field-rechargeable with electrolyte, at just 20% of the cost of traditional sensor replacements. Routine maintenance averages $70 per year, saving your operation hundreds annually while ensuring long-term safety and reliability.

True Stand-Alone Monitoring—Plug in and Protect

Designed for easy, stand-alone operation, PureAire’s Arsine Gas Detector is ready to go right out of the box. Simply mount it near the risk zone, plug it into any 115VAC or 220VAC outlet, and start real-time monitoring with no complicated setup. The detector includes a built-in horn and bright LED alarm indicators that immediately alert staff to dangerous arsine gas levels. Need integration with a broader safety system? No problem. The unit features individual alarm and fault relays, plus an analog 4- 20mA output that easily connects to remote PLC or SCADA systems.

Smart, Self-Monitoring Technology—Peace of Mind 24/7

Behind the scenes, the “smart” electronics of the PureAire Arsine Gas Detector are hard at work 24/7. The system continuously monitors itself for errors, and any fault instantly triggers a signal to your control room via the analog output and fault relay. Maintenance is streamlined too: the sensor’s built-in microcontroller stores calibration data, so you can easily remove it from the transmitter for service, then plug it back in without missing a beat.
