Oxygen Solutions. If you use an inert gas, such as nitrogen (N 2) in brewing, dispense applications to make a smooth beer or in modified atmosphere packaging (MAP) to preserve foods by chilling, freezing or pressurising packaging then you need an oxygen (O 2) monitor.. If a nitrogen (N 2) leak occurs it can displace the oxygen (O 2) in the air you breathe which can be fatal.

Often called the invisible killer, carbon monoxide is an odorless, colorless gas created when fuels (such as gasoline, wood, coal, natural gas, propane, oil, and methane) burn incompletely. In the home, heating and cooking equipment that burn fuel are potential sources of carbon monoxide. Vehicles or generators running in an attached garage can also produce dangerous levels of carbon monoxide.
That''s right. Since the most powerconsuming part in a gas leak alarm is the sensor, which is the core of the alarm, to create a sensor having ultralow power consumption, we needed to develop a technology for making the sensor smaller and thinner. I guess developing this technology for making a sensor smaller and thinner was difficult. Yes.
