SGF104 – Oxygen Sensor

Gas Detection

The SGF104 has been introduced by Duomo at the request of architects and consultants to provide a more architecturally discrete enclosure without compromising the sensitivity of detection. The SGF 104 Oxygen sensor measures oxygen depletion and excess oxygen.

SG104 Product Description

The Duomo SGF104 Oxygen Sensor measures Oxygen depletion or excess Oxygen in the air. Other sensors within the range sense Natural Gas, CO, Freons, H2S, Hydrogen, and LPG. Suitable applications for the SGF104 include:

•Research & Teaching Laboratories
•Food & Manufacturing
•Assembly clean rooms

Where a risk, for example, of Nitrogen (or any inert gas) leaking may reduce oxygen content within an enclosed environment.
