QAL991 Datasheet QAL991 Datasheet
The QAL991 uses PCME’s unique AC Electrodynamic technology, an advanced Triboelectric method. The DC signal that is created by particles colliding with a probe inserted in a stack, is electronically rejected, leaving an AC signal resulting from charged particles passing and interacting with the rod.
Since the frequency signal has been specifically optimised (Electrodynamic technology), the instrument has reduced cross sensitivity to changing velocity and has increased stability even with dust build-up on the sensor rod. The dust signal is amplified, digitised and processed at the sensor, consistent with good signal to noise design techniques.
In constant processes using bagfilters (where typically particle-charging characteristics are constant), the processed signal can be correlated to dust concentration using a Standard Reference Method (SRM) according to a QAL 2 calibration.

FEATURES
• The instrument’s automatic self-checks are extended to provide zero, span and contamination tests which assess uncertainty and to record results for later statistical analysis. This provides the infrastructure for QAL3 tests according to EN14181.
• Optional PC software ‘QAL Reporter’ provides secure emissions and QAL3 reporting. It includes the statistical treatment of the zero and span results for the user to demonstrate that the instrument is operating according to defined specifications (uncertainty).
• An optional reference ‘AST linearity tester’ is provided as a test accessory to demonstrate linearity as required by the Annual Surveillance Test (AST).
• The measurement and calibration features are extended to facilitate a 15 point 3 day calibration (QAL2) and permit the specification of a valid calibration range
