Two Channel version measures at two wavelengths simultaneously with possibility to see current scan.
More wavelengths or scan are used in liquid chromatography to verify purity of analyzed samples or in situations when some peaks absorb on different wavelengths.
Most important features of TOY18DAD H detectors:
- built-in lamp working hours counter
- easy replacement of flow cell
- measuring at more wavelengths simultaneously
