Набор для технического обслуживания (мембранная крышка и карта Micro-SD с калибровочными данными)

The service set for the optical oxygen sensor type Oxi L 400 contains a long-life membrane head and a SD card with calibration data as well as a software package for data processing. The calibration data are specifically aligned to the respective luminophore covered membrane. A serial number on both SD card and membrane head helps to check for conformity.
