Overview
2-pentenenitrile rapid detection tube detector toxicity tube testing tube $r $n2- The 2-pentenenitrile detection tube is a sealed, slender glass tube that presents a specific color due to being filled with specific reagents and coloring agents. When a gas sample containing 2-pentenenitrile enters the detection tube, a chemical change occurs, causing a color change. The scale corresponding to the boundary of color change observation is the concentration of 2-pentenenitrile in the tested sample.
