RG 399

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
