Product OverviewThe Uniphos FumiGuard is a continuous gas detection system for perimeter and fence-line monitoring of fumigated areas. It comprises a master controller and up to 8 modular detection heads that can be connected in a daisy-chain (loop) to minimise cabling. Built-in GSM connectivity uploads measured readings to the cloud for remote viewing and configurable alarms, enabling continuous perimeter monitoring and assistance with regulatory compliance.
Application- Online perimeter and fence-line monitoring of fumigated storage, silos or treatment zones.
- Detection of PH3 at TLV levels for worker safety and site protection.
