- The PCME STACK 710 uses a homogeneous advance LED light source to reduce the effect of misalignment on the measured opacity. Together with a 'Flood LED', the instrument achieves the highest levels of stability and accuracy. The 'no moving parts' optical system gives an instrument with exceptional reliability and proven low measurement capability beyond most standard Opacity monitors.
- The PCME STACK 710 has fully automatic zero and drift compensation system. An automatic span check mechanism confirms the instrument calibration at user-defined intervals (1 to 24 hours in 1 hour steps).
- Optional automatic fail-safe shutters can be fitted to temporarily protect optical components from dust or corrosive gases in the event of an air purge or power failure.
