Product Overview
The MultiFlame DF-TV7-T is a multi-spectrum infrared flame detector that uses three independent IR wavelengths to detect hydrocarbon fires while maintaining excellent immunity against false alarms.
It is designed for harsh marine, offshore and petrochemical environments, including smoky or dirty locations where conventional detectors may experience reduced performance.
