What is a CH1 file?

CH1 files mostly belong to OxySoft NEO/OXYVIEW, GraphPad Chart. CH1 files are not general documents; they are specialized files used by specific scientific software.

Another type is identified as a GraphPad Chart File, used to save chart configuration and visualization settings. This variant is associated with the GP2CHART system and is designed for scientific plotting.
Details include:

Creation: The file structure is defined by the originating instrument or software.

Usage: Open with the vendor-recommended application (OxySoft NEO/OXYVIEW for oxygraph data or GraphPad Chart for chart files).

Content: The file may embed extra metadata essential for accurate data interpretation, such as calibration data.
