ISOWAT needs the rack drawer for its pump and calibration unit DesiredCabinPosition:: close to inlet. Connection via heated (80°C) 1/4" stainless-steel tuning. ModificationNumber:: AdditionalRequirements:: Weight:: 40 Type:: insitu Summary:: The ISOWAT instrument is a new development, which is based on the technique of tuneable diode-laser spectroscopy. The sample air is drawn into an absorption cell, and the absorption of laser radiation due to the water molecules is detected. Using a H2O calibration standard of known isotopic composition, the isotopic ratios within the atmospheric air sample can be determined. Weight 40 kg total excl. fraction of rack Status:: 1
