Claims
- 1. A gas analyzer of the type that uses the principle of optical gas analysis comprising:an appropriate cuvette flowed through by a gas to be measured, said flowing gas providing a measuring pressure in said cuvette; said cuvette having a window region placed near an analysis space and said cuvette surrounded either only in said window region or overall by a chamber that isolates any leakage from said measuring cuvette when said gas analyzer is analyzing a toxic and/or corrosive and/or combustible gas that flows thru said analysis space said surrounding chamber is purged with inert gas or air and having a pressure higher or lower by comparison with said measuring pressure of said cuvette.
- 2. The gas analyzer of claim 1 further comprising a flow sensor for monitoring flow of said inert gas or air to regulate said inert gas or air flow.
- 3. The gas analyzer of claim 1 further comprising a processing unit.
- 4. The gas analyzer of claim 3 wherein said processing unit is an electronic unit.
