Product Specifications
The Macurco TX-6-HS is a low voltage, dual relay Hydrogen Sulfide (H2S) detector, controller and transducer. The TX-6-HS has selectable 4-20 mA output, buzzer and digital display options. It is an electronic detection system used to measure the concentration of H2S and provide feedback and automatic exhaust fan control to help reduce H2S concentrations in refineries, pulp and paper mills, waste disposal or other commercial applications. The TX-6-HS is a low-level meter capable of displaying from 0-50 ppm of Hydrogen Sulfide.
