If you think you have a problem with your LISST or HydroLight / EcoLight-S product you can contact our support staff via email or phone +1(425) 641-0944.

For questions related to LISST data quality we always need to know the following:

  • LISST type and serial number (e.g. LISST-Portable|XR sn 785)
  • The raw data files(s) you are concerned about. These have a .DAT or .LOG extension depending on instrument type and model.
  • For a LISST-100X, the background (zscat) file you used for data processing.

For hardware questions we always need to know the LISST type and serial number. Please provide us a detailed description of the issue and what you were doing at the time when you discovered the issue.
