By the Methods

Imitated by others without success, compatible with Android 7.0 (NOUGAT)

"This is the best method available for your calculations, and it’s always with you – right in your pocket!"

By the Methods is not a cheap re-write of poorly written, worthless programmable calculator scripts from the 80's but rather an intuitive and modern implementation of calculations and data capture for stack testers. By the Methods has ongoing support while others have stopped at 4.0.4

By the Methods is a suite of software tools and utilities for performing procedures that precisely conform to the US EPA stationary source testing and monitoring methods with unmatched precision. The tools also support standard conditions defined by NIST, IUPAC, and GOST.

Only EPA Method 30B application on the market!!

Only EPA applications that saves all data to Microsoft Excel® files, why just check your numbers when you can perform your entire test and save your work for historical verification data.

English OR Metric OR ANY COMBINATION OF THE TWO SYSTEMS for input and results; not just English OR Metric. Units of measure for every input is always displayed, always selectable and easily saved to Microsoft Excel®.

By the Methods does Method 1 (Circle, Elliptical, Square or Rectangle), Method 2, Method 4, Method 5 plus Method 30B and 3 useful utilities. All with unmatched precision.

All data is easily viewable on a single, scrollable display, and saved to your SDCARD as date and time stamped Microsoft Excel® spreadsheets for later use and verification.

Each tool and utility checks requirements set forth in the US EPA Methods, alerts users when data is incorrect, and highlights the section, table or figure used for easy look up and verification.

This is hands down, the best method available for your calculations, and it’s always with you – right in your pocket!
