This calculator is now integrated (as of Version 1.0.3) into the Sample Data Editor.

Allows for the entry of raw particulate filter weights, recall of flow and pressure data, and calculation of the final PM concentration value.

Flow and pressure data is automatically calculated for the entered sample data by retrieval of 1-hour data from the site using the PMVOLUME, AMBTEMP, and BARPRESS Parameter Templates and computation of a 24-hour value from those results. If those parameter templates are not found, the field is left blank for manual entry by the user.
