The Spectros Instruments Sulfuryl Fluoride (SO2F2) Portable Monitor (SF-ExplorIR™) is designed to detect, measure, and display the concentration of SO2F2 gas in the area being monitored. To ensure accurate gas measurements, the monitor self-zeros every 4 minutes using its internal supply of fresh air.

Front panel indicators and an audible alarm are provided to signal gas alarm and instrument fault conditions. The audible alarm can temporarily be silenced by a push of a button, but will reactivate if the gas level is still above the alarm trip point after a user-defined time period has elapsed. The SF-ExplorIR™ Monitor requires only minor periodic maintenance such as the annual replacement of internal particle filter and fresh air bag.

The monitor incorporates active diagnostics that continuously check the system for proper operation. A front panel indicator is provided to alert an operator of system malfunctions, and fault codes are generated that enable the operator to quickly identify the cause of the fault.

The SF-ExplorIR™ is available from all Air-Met offices for sale only. Contact us today for more information.
