Fixed Gas Detector
GD-70D series
GD-70D
Features
GD-70D series is a gas detector head to detect toxic gas, oxygen, and combustible gas generated at semiconductor and liquid crystal factory, etc. The reduction of an environmental load has been achieved by reuse of the sensor substrate and recycling of components.
