Hydrogen Sulfide BTI

(3.5” x 1”, ¾” male NPT)


The Hydrogen Sulfide Gas Breakthrough indicator for Activated Carbon Adsorbers and Filters is a colorimetric indicator that indicates the saturation and exhaustion of carbon adsorbers and filters. The indicator is reliable and cost effect means for protection from exposure to toxic hydrogen sulfide gas in the work place. The indicator change color from light blue to brown to black when carbon absorber or filter is saturated with Hydrogen sulfide. Hence alerting the user to replace the exhausted carbon absorber or filter. The indicator is easily connected to the ¾ inch female NPT outlet of the carbon absorber or filter using the ¾ inch male NPT threading at the bottom of the indicator. It is highly sensitive to hydrogen sulfide gas. It operates at temperatures -20oC to 65oC (-4oF to 149oF) and humidities 5% RH to 85%RH. The indicator is 3.5 inch tall, 1 inch diameter and you can observe the bright vibrant color change from all directions. The unique design of the indicator prevents any color change due to exposure to contaminants in the surrounding environment and changes color only when carbon absorber or filter is saturated. The indicator has extended service life of 2 years.
