RG 399
Analisador de gás de fumo
Application
The flue gas analyser RG 399 is suitable for supervising exhaust and process gases that contain traces of corrosive gas and /or dust. The gas preparation before analysing, is achieved by way of a double-filter that is self-regenerating.
Fields of Application
- Supervision of flue gases
- Supervision of boiler installations
- Supervision of process and exhaust gases
- and many more
Features
- Various types of measurement sensor can be used
- Long service life of the measurement sensors is ensured by including a pre-cleaning of the test gas to remove any corrosive components
- Gas conditioning specific to the application by the use of various types of filter medium
- Automatic regeneration of the filter used
- Suction system, thus hot test gases can be monitored
- Integrated flow control
- Direct recognition of the warning status by way of a coloured LC-Display
- Menu-assisted operation via two keys
- Three alarm levels, independently adjustable from 5 to 100% of the measurement range
- Three floating alarm outputs for controlling external warning and control devices
- Floating fault contact
- Serial output RS 232 or RS 485
- 4-20 mA current interface
- Various designs of housing are available, for example, 19" rack system, wall-mounting housing
- High standard of service reliability
- Low current consumption
- Un-interruptible power supply (UPS) is available
