Falco TAC Fixed Gas Detector - Diffused Model

The Falco TAC diffused is a fixed gas detector that eliminates false readings found with other competing fixed gas detectors and continuously detects Volatile Organic Compounds (VOCs) in hazardous areas. The Falco TAC diffused, fixed gas detector is ideal for detecting VOCs in areas such as refineries and petrol chemical facilities.
