1019196 Includes Only:Base plate with coil and holder for Hall sensors3 Material samples (Vacon 11, spring sTeel and silver sTeel)Digital Spectrometer LD with Absorption Chamber. 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 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.
