Fixed gas monitoring system
to monitor biogas plants and landfill sites |
|
Features
Modular system concept; optional one or two gas sample inputs;
several sensor combinations are possible
Instruments with two gas sample inputs allow H2S measuring
before and after desulphurisation
Long lasting electro-chemical sensors thanks to fresh air
flushing via solenoid valves at intervals
internal pump
micro-processor controlled
permanent and fully automatic measuring sequence
simple operation
large, illuminated LCD
Continuous self-test during operation
all components resistant against aggressive gases
dust and spray-water proof
internal data storage
serial port RS-232 for permanent data output (e.g. when connected
to process control) or for read-out of data storage
sensor operation independant of variations in temperature
individual instrument configuration by function menu; protection
of settings by PIN code |
