Polispec VIS-NIT is an extremely robust spectrophotometric sensor, designed to be connected via fibre optics to a variety of measurement probes and lighting sources. It is available in the spectral ranges between 340 and 1100 nm. Thanks to its particular compactness, Polispec VIS-NIT can be easily integrated into any point of a production line. This instrument is equipped with two programmable internal signal modulators to make it efficient even in processes in which the work dynamics are very different from each other in order to avoid having to adapt the system with hardware devices. The casing is made of anodised aluminium and is available with different levels of protection from liquids and dusts.
The software interface was developed in the logic of process systems to be easily integrated into the system and with PLC modules. The entire system, consisting of Polispec VIS-NIT and the management software, can therefore be supplied with different protocols and communication interfaces, so that the integration work is minimal for the customer.

poliPROCESS: for in-line measurements for interfacing with PLC automation. Available for continuous acquisitions for filtering and for real-time chemometric predictions.

poliDATA: fully automated software for stand-alone and laboratory acquisitions and chemometric predictions.

poliADK: Windows ADK for software developers. ADK is able to independently manage the optimal settings of the instrument, including calculation of the optimal integration time. The reference acquisition procedure is also automated and is used to apply pre-treatments such as smoothing or interpolation of the spectra. It also extracts raw and post processed spectral information.

ITPhotonics software is compatible with the SensoLogic and UCal Chemometric calibration suites.


And the field of application is not an obstacle, because our preparation allows us to collaborate with multiple sectors, identifying the needs of individual targets.

Professional spectrophotometers for portable and on-line analysis. They have no limits in their applications thanks to their great application versatility and easy integration.
