The indicator change color from light blue to black when carbon absorbers and filters are saturated with hydrogen sulfide. Hence alerting the user to replace the exhausted carbon absorber or filter. The indicator is easily connected to the 1½ inch female NPT outlet of the carbon absorber or filter using the inch male NPT threading at the bottom of the indicator. It is highly sensitive to hydrogen sulfide. It operates at temperatures -20oC to 65oC (-4oF to 149oF) and humidities 5% RH to 95%RH. The indicator is 4.5 inch tall, 2 inch diameter and you can observe the bright vibrant color change from all directions.
