Spectraval 1511 NIR Spectroradiometer

Spectraval 1511 is a modern spectroradiometer for the VIS to NIR wavelength range , which can be used stand alone or with PC/ laptop. It is constructed in the same way as spectraval 1501, but includes a display. All other functions are similar
Spectraval 1511 can be used for spectroradiometric measurements in the field without additional computer or via Bluetooth/ USB connection with different PC programs like the included universal radiometric software JETI LiVal or other programs as CalMAN (spectracal), ChromaPure (Display Calibrations), LightSpace (LightIllusion), Argyll and HCFR (under preparation).
