$87.84 /Box

Gastec™ Hydrogen Sulfide Gas Detector Tube features 2 - 10 pump strokes and 1/2 - 1/10 correction factor for 0.25 - 2.5 ppm measuring range, 1 pump strokes and 1 correction factor for 2.5 - 60 ppm measuring range and 1/2 pump strokes and 2 correction factor for 60 - 120 ppm measuring range. Detector tube has sampling time of 1 min per pump stroke for 0.25 - 60 ppm and 30 sec per pump stroke for 60 -120 ppm. It is ideal to detect hydrogen sulfide in the air or in industrial areas and for determining the environmental atmospheric condition. Detector with 0.1 ppm detecting limit, changes color from White to brown.

Use this tube for detecting Hydrogen sulfide Seine the air or in industrial areas and for determining the environmental atmospheric condition

When breaking the tube ends, keep away from eye
Do not touch the broken glass tubes, broken pieces and reagent with bare hands
The sampling time represents the time necessary to draw the air sample through the tube
The tube must be positioned in the desired sampling area for the entire sampling time or until the flow finish indicator indicates the end of the sampling
