Digital spectrometer for quantitative analysis of emission and absorption spectra, for recording transmission curves and performing measurements in calorimetry and kinetics. Incident light from a fibre-optic cable is dispersed into a spectrum by a Czerny-Turner monochromator and projected from there onto a CCD detector. The entry slit is built into the casing. User-friendly measurement and evaluation software enable simultaneous recording and analysis in real-time. The built-in software for Windows 2000/XP/Vista/7/8/10/11, 32- and 64-bit versions starts running as soon as the sensor is connected to the computer via a USB cable. Includes plug-in power supply and holder for fibre-optic cable.
Absorption Chamber is a multi-functional module for recording transmission or absorption measurements using 4-ml cells (10 x 10 x 40 mm³), objects in slide format (50 x 50 mm²) or objects in coin format (40 mm diam.). Up to two slide-format objects and one coin-format object can be analysed simultaneously and compared. With built-in light source for the spectral region from 350 – 1000 nm. In metal casing resistant to chemicals. For direct connection to digital spectrometers LD or via fibre-optic cable. Refer also to experiment UE4020400.
