The ISA (In Situ Spectral Analyser) is a spectrometer which works in the wavelength range between 200 and 708 nm (UV-VIS). The result of a single measurement is an absorption spectra over the whole wavelength range.
A spectrometer is a very multi-purpose measuring instrument because it can be implemented in very diverse applications through a relevant calibration. Multi-parameter measurements are also possible. This is a great advantage in comparison to electro-chemical sensors. Moreover, ISA offers an adjustable measuring-path-length whereby the number of potential applications is increased even more.
A great advantage of ISA is the special coating of the glass plates in the measuring-path. Combined with the possibility to automatically clean the measuring section with compressed air, ISA achieves very long in-ser vice times and maintenance intervals.
Only the optics and the compressed air cleaning are integrated into the V4A-steel sensor head. The entire control- and analysis-electronics are mounted in the accompanying sensor module or the BlueBox TS. ISA is thereby usable in a high temperature range (up to 110°C). This earmarks ISA for use in medicine or the food industry because the sensor head can be sterilised at high temperatures.
