Portable gas detectors
These products are ideal for inspections before personnel enter tanks, manholes, or other locations that pose the risk of oxygen deficiency. They can also be worn on one’s person when handling hazardous gases.

Detection method
・Diffusion type
Diffusion type gas detectors detect gas leaks that come into contact with a sensor. They are worn on the person by workers to alert the user to hazards when gas is detected in the surroundings, allowing the user to move to a safe location.
・Suction type
Suction type gas detectors have a built-in pump. Therefore, when working inside a tank or any other place where there is a risk of oxygen shortage, the hose connected to the gas detector can be placed inside the tank to detect the gas and confirm safety before work.
