The 74 series spectrophotometers provide accurate and reliable results in various applications from teaching, to industrial applications, to routine sample analysis in quality control environments. These spectrophotometers have been designed to be easy to use and have enhanced connectivity for simple and quick data transfer. All units feature a colour touchscreen and intuitive user interface, allowing manual free operation.
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 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.
