GM700
|
|
| |
In-situ TDLS analyzer for ammonia, oxygen, hydrogen fluoride or hydrogen chloride Reliability, precision and minimum response times - these are the decisive facts of the GM700 TDLS analyzer from SICK MAIHAK. Tailored for the measurements of gaseous components for example ammonia under harsh conditions. Applications Using the GM700 processes can be more efficient, for example in power stations, waste incineration plant, as well as in cement, steel, chemical and petrochemical industry.
The characteristics of the GM700 suits it outstandingly for emission minimizing with prototypes or optimizing of engines on roll benches.
