The PCME STACK 710 Opacity monitor is designed to meet and exceed US EPA PS-1 requirements for Opacity measurement from combustion stacks. The instrument provides low level measurement capability through advanced LED design, has no continuously moving parts, and offers class leading performance through outstanding reliability.
As part of the ENVEA UK family of products, the PCME STACK 710 supports multi-sensor Modbus networking, stand-alone operation or easy integration into existing plant control systems.
Key Features
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.
- Automatic Self Checks
