Hydrogen Sulfide Detector Controller and Transducer
Provides automatic fan control to help maintain acceptable levels of H2S in refineries, pulp and paper mills, waste disposal and other commercial facilities - Can be used as a stand-alone detector and controller and as an analog transducer for use with the DVP-120 and other systems
– ETL Listed

Hydrogen Sulfide or H2S, also called sewer gas, is a colorless gas with a strong odor of rotten eggs. Note: Sense of smell becomes rapidly fatigued & can NOT be relied upon to warn of the continuous presence of H2S. The TX-6-HS is designed to meet the NIOSH and OSHA standards for Hydrogen Sulfide exposure limits.

TX-6-HS - 12-24VAC or 12-32VDC input and TX-12-HS - 100-240VAC input

• 5A SPDT Fan control relay
• 0.5A N.O. or N.C. Alarm Relay
