Phosphine Gas Detector

$2,170.00

Product Summary

The PureAire Phosphine Fixed Gas Detector offers continuous, real-time monitoring of phosphine (PH₃) gas, delivering precise detection in critical environments where safety and reliability are non-negotiable. With a dedicated electrochemical sensor calibrated in parts-per-million (ppm), the detector is designed to quickly identify phosphine leaks before they pose a serious threat.

Phosphine is widely used in the semiconductor industry, particularly in doping processes during the fabrication of integrated circuits and photovoltaic devices. Due to its high toxicity and flammability, phosphine presents significant safety risks, even at low concentrations, which is why accurate gas detection is essential in cleanrooms, gas cabinets, and wafer processing areas.

PureAire’s phosphine sensors are engineered to last up to 8 years in controlled manufacturing environments. They are also rechargeable on-site with electrolyte, reducing maintenance time and lowering the total cost of ownership.

For semiconductor fabs and advanced manufacturing facilities, PureAire delivers a robust, low-maintenance phosphine detection system that protects personnel, equipment, and the integrity of high-precision production lines.

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 Phosphine 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 phosphine gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Phosphine 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 phosphine sensor cell programmed with gas and measurement range information. When servicing the phosphine sensors, they can be recharged with fresh electrolyte and dynamically gas-calibrated in the maintenance shop away from the transmitter.

Low Annual Operation Cost Without Sacrificing Safety

The PureAire Phosphine Gas Detector offers unmatched reliability at the lowest annual maintenance cost on the market. Unlike traditional disposable sensors, our renewable phosphine sensors can be quickly recharged with electrolyte right in the field, at just 20% of the cost of standard sensor cell replacements. With routine maintenance supplies averaging $70 per year, this detector delivers industrial-grade performance while saving you hundreds of dollars annually.

Truly Stand-Alone. Instantly Operational.

Setup is effortless with the PureAire Phosphine Gas Detector. It’s a fully self-contained system, requiring no external controllers. Simply mount it near the hazard zone, plug it into any 115VAC or 220VAC outlet, and start monitoring. If phosphine is detected, the built-in horn and LED alarm indicators provide immediate alerts. The unit also features dedicated alarm and fault relays, plus a 4–20mA analog output for seamless communication with your PLC or SCADA system.

Smart, Self-Monitoring Electronics

This detector doesn’t just monitor gases—it monitors itself. Equipped with 24/7 continuously supervised electronics, the system instantly alerts personnel of any internal fault via analog output and fault relay. The sensor’s onboard microcontroller stores calibration data, allowing for quick, easy removal and reinstallation during routine maintenance. Once reconnected, it automatically syncs with the transmitter—no reprogramming required.

Efficiency Meets Reliability

From fast setup to low-cost upkeep and smart self-checks, the PureAire Phosphine Gas Detector is built to simplify your safety program while maximizing operational uptime. It’s the dependable, budget-friendly solution for facilities that need to monitor phosphine gas with confidence.
