Open Path (OP) Fourier Transform Infrared (FTIR)

Spectrum's WaveRunIR -OP is the next generation of Open Path (OP) Fourier Transform Infrared (FTIR) Monitoring Instruments. Compact and rugged, the WaveRunIR-OP is compliant with USEPA TO-16r and ASTM 1982.

Easy alignment and high signal throughput allows for single-digit part per billion detection limits to be realized for most of the 500+ compounds in Spectrum's library. Each WaveRunIR-OP instrument is capable of monitoring path lengths up to 1,500 meters (round trip) and when equipped with a pan/tilt positioner, can scan multiple paths.

If a source of collocated meteorological data is present, WaveRunIR-OP can easily be integrated into a larger, more complete fence line monitoring solution providing near real-time leak and release emissions detection from the facility.

Coupled with Spectrum's TsunamiTM data management system and SmartPathTM, the WaveRunIR-OP is the backbone of the most advanced, secure, integrated, LAN or cloud-based Fence Line Monitoring Solution in the industry.
