www.mksinst.com Precisive® 5-271 SYNGAS COMPOSITION, CALORIFIC VALUE, AND W OBBE INDEX MONITOR the Precisive® 5-271 is designed specifically for on-line quality monitoring of syngas derived from a variety of fuels, including coal and biomass. i t provides fast and accurate measurement of c alorific Value, wob be i ndex, and compositional information, including co2 in a single, compact analyzer. Based on a unique tunab le Filter s pectroscopy ( t F s™) platform from mks, the analyz er directly measures the component concentrations and calculates gas property values based on widely-accepted iso standards. Features & Benefits
- Analysis in seconds Real-time , continuous measurement F ast response (seconds)
- No carr ier gas or fuel gas requirements Lo w operational costs and infr astructure requirements s uitable for small-scale plants and ter minals i deal for remote installations
- Robust calibr ation Reduced maintenance and oper ational costs Flow-through sensor design Compact, outdoor r ated, lo w po wer — NEMA and IP-66 r ating, can be engine or manif old mounted Engineered to withstand vibr ation and shoc k
