Kitagawa 100 Carbon Monoxide Gas Detector Tube 5-300 ppm / 25-1000 ppm

Kitagawa Gas Detector Tube change colors when chemical reagnets filled in a glass tube react with sampled target gas through the tube. The stain created is proportional in length to the concentration of the target gas, so the concentration is read directly off the printed scale on the tube.
