In order to prevent an oxygen depletion or toxicity accident, or an explosion of a flammable gas, on an oil tanker or a chemical tanker, for example, it is necessary to correctly measure the concentration of oxygen and also to measure the concentration of toxic gas or flammable gas. Gastec produces detector tube type gas measuring instruments, and also extension sampling tubes of 30 m which is the optimum length for downward-facing remote measurement in tanks, for example. In addition we have a wide range of compact and lightweight measuring instruments which have excellent operability.
