spectraval 1511(VIS+IR)

spectraval 1511 is a modern spectroradiometer for the VIS 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
