Product Features
There are two models in the 74 series range. Model 7410 uses a tungsten halogen lamp for measurements in the visible spectrum from 320 to 1000nm. Model 7415 uses a press to read xenon lamp to extend measurements into the UV spectrum, down to 198nm. Both spectrophotometers have a 5nm spectral bandwidth and are covered by a 3-year warranty, including the Xenon lamp used on the 7415 but excluding the Tungsten lamp used on the 7410 which has a 1 year warranty.
Both models offer measurement modes for simple photometrics; concentration calculated using a single standard or a factor; quantitation with the ability to create a calibration curve using up to 20 standards; full spectrum scanning; multi-wavelength, where up to 4 wavelengths can be measured simultaneously and kinetics, to monitor the change in absorbance over time.The large 7" High Definition colour touchscreen enables users to zoom in and out and select points all by simply touching the screen. The touchscreen interface is fast and responsive even when wearing gloves.
