Viavi Solutions has introduced the MicroNIR™ PAT-L and PAT-Lx NIR spectrometers for in-line liquid process monitoring. The PAT-L is built for ordinary process locations, while the PAT-Lx is designed specifically for hazardous locations (ATEX, NEC and IECEx certified). The MicroNIR PAT-L/Lx are fully integrated NIR liquid probe systems that do not require fibre optics. Since their spectrometer engine has no moving parts, they are highly stable over time and intrinsically free of the need for maintenance. The MicroNIR PAT-L/Lx are optimised for in situ liquid monitoring, with less than 1 s acquisition time while maintaining a high signal-to-noise ratio. The PAT-L/Lx provide a scalable multi-point monitoring solution that does not rely on central multiplexing systems.
