​Vaisala vLog SP (formerly Spectrum) is a trend analysis software for downloading, analyzing and reporting information from Vaisala SP data loggers. This software is used in standalone data logging applications with Vaisala's non-validatable DL-series data loggers.

  • Create graphs and reports from logger files
  • Produce detailed graph reports and statistical summaries
  • Overlay logger files within the same graph to check relationships between logger files
  • Add manual and automatic maximum, minimum, and average lines to graphs
  • Create customized tabular-format reports with date/time, logged values, interval statistics
  • Copy/paste and export graphs to .TXT and .CSV files into Windows and/or other data base applications
