The Macurco TX-12-HS is a line voltage, dual relay Hydrogen Sulfide (H2S) detector, controller and transducer. The TX-12-HS utilizes an internal switching power supply that is capable of using line voltage between 100 and 240VAC and 50-60Hz.The TX-12-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-12-HS is a low level meter capable of displaying from 0-50 ppm of Hydrogen Sulfide. The TX-12-HS is factory calibrated and 100% tested for proper operation, but can also be calibrated in the field.
