* Also referred to as "between-parts variation" or "device-to-device variation".
** Lifetime is based on mean-time-to-failure (MTTF) calculation of the manufacturer and might vary depending on different operating condi-
tions.
***Specification validated fo a mix gas that represent a typical concentration of TVOC. The indicated data are valid for this mix gas. In uncon-
trolled environment, the mix gas can change and vary, and associated TVOC values can change too.
