Established in 2007, Precisive has developed an innovative optical sensor technology for on-line gas and liquid chemical monitoring. Our hardware platform is based on Tunable Filter Spectroscopy (TFS) providing fast, rugged and high-precision spectral scan in the ultraviolet, visible and infrared wavelengths. Coupled with an advanced spectral decomposition algorithm, our sensors provide accuracy level and speciation capability unmatched by any other optics based sensors and analyzers in the industry.
