​Quick Visual of Results

Interface includes horizontal bars that move automatically with min, max, and avg values. Superimpose up to 4 indicators wherever you want—set the value, units (temp or RH), label, and color for each indicator.

Detailed, Customizable Graphs 

Add statistics such as min, max, and avg values, max minus min value, max minus avg value, avg minus min value, group statistics to your graphs. Use more explanation in the signoff area with up to 6 lines of text to describe the run.

Detailed Graphical & Tabular Reports

Use the graph overlay to highlight relationships between files, or use zoom or cursor pin-point to highlight actual values, times and dates.

Horizontal lines dynamically track min, max, avg – or add your own.

Reports are presentation-quality.

Easy Data Transfer

Copy and paste or export graphs, TXT and CSV files into other Windows and/or database applications

Quickly, conveniently download data from your loggers, using automatic filename creation with descriptive naming.

Easy Logger Configuration

vLog SP software allows you to quickly set up multiple loggers with similar properties, or set each logger individually. Set sample rates, synch start/stop times, enable/disable channels, set user-defined measurement units, and adjust memory modes (stop when full, wrap-around when full, etc.)

Flexible Graph Scaling

Customize graphs with manual or automatic scaling, multiple Y-axes, selectable decimal place precision, temperature unit display options (°C or °F), and user-adjustable International date and time formats.
