H2S Data Logger-GHS-8AT-EX
Overview
Continuous H₂S monitoring is straightforward, convenient, and dependable. When corrosive hydrogen sulfide forms in sewer systems, it can cause corrosion, leading to rust, unpleasant odors, and, in severe cases, significant damage to buildings and infrastructure. The GHS-8AT-EX data logger enables continuous, reliable monitoring of H₂S levels within the sewer system.
