QAL 991 – DUST / PARTICULATES MONITOR

QAL 991 – DUST / PARTICULATES MONITOR

Suitable for industrial processes controlled with dry scrubbing and high efficiency bag filtration.

Industrial processes controlled with dry scrubbing and high efficiency bag filtration
Non-condensing / dry flue gases*
Constant or variable velocities within range 8-20m/s (typical bagfilter velocity ranges), constant velocity required outside this range
Not suitable for electrostatic precipitators or applications with water droplets*

Applications:

Specifications:

System self-checks, with logging of Zero and Span check data for QAL3 reporting and probe rod short circuit check to detect (hence avoid) electrical shorting to the stack
QAL Reporter PC software option to provide secure and powerful emissions reporting and automated QAL3 reporting in full compliance with EN 13284-2
Entry and Standard control units with advanced graphics and user interface screens, features including alarming, graphical trending, data logging, 4-20mA output.
PLUS control unit option for sensor networking (up to 16 sensor channels) via industry standard Modbus, multiple inputs for external devices (e.g. for Temp and O2 normalisation)
