SF400 Series

Sulfuryl Fluoride Monitors

Multi-Zone Fumigation Monitoring

The rugged, modular design of the SF400 delivers unmatched sulfuryl fluoride fumigation performance. The user may access multiple sampling points onsite or remotely via a secure encrypted web portal. Sulfuryl Fluoride concentration values for each zone are viewed in real-time then automatically archived for later review. This actionable intelligence transforms raw data into informed decision making.

Online Monitor Portal

A diversified sensor platform for fumigation that allows users to track gas concentrations, temperature, relative humidity and more from any remote location. Our monitors continuously transmit accumulated data securely, via Amazon Web Services (AWS), using 256-bit SSL encryption to prevent security risk to your firewall configuration.

The portal visualizes:

Real-time concentration readings from multiple sampling points
Graphing of concentration over time for all points
Details about each sensor
Job specifics: location, time zone, fumigant, commodity, environment and scheduling
Status conditions and alerts

This actionable intelligence transforms raw data into informed decision making.
