The Uniphos FumiGuard is an advanced continuous gas detection system for detecting Phosphine (PH3). It has been specially designed for applications like fence line or peripheral monitoring of a fumigated area.  

It comprises of a master control unit and up to 8 gas detection heads. The modular design of the system enables the user to easily connect multiple detection heads in a loop (daisy chain), saving cable cost in the process. With in-built GSM connectivity, the gas readings are uploaded to the cloud, where they can be viewed from anywhere in the world on a laptop or mobile device and alarm functions can easily be configured, allowing 24/7 perimeter monitoring and ensuring compliance to local regulations.
