As an extension of the FM approvals received last year for the Ultima X5000 and General Monitors S5000, we are pleased to announce that the TruCal Diffusion Supervision sensors for Hydrogen Sulfide and Carbon Monoxide have received FM approval.

The TruCal Diffusion Supervision sensors extend calibration intervals to an unprecedented 2-year interval saving customers time, resources and money. They join the originally released sensors that also have FM approval – combustible (catalytic bead and point IR detectors), oxygen, hydrogen sulfide and carbon monoxide (non-diffusion supervision versions).
