By the Methods' tools and utilities feature both universal input and results, allowing for English, metric, or any combination of the two systems. Just tap any unit of measurement and choose your desired system for that input. The tools and utilities also support standard conditions defined by NIST, IUPAC, and GOST.

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.
