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.
The TX-12-HS meets the NIOSH (National Institute for Occupational Safety and Health) and OSHA (Occupational Safety and Health Administration) standards for gas exposure.
