Number of Cartridges Per Aethair PRO
Aethair PRO supports up to two standard Aethair Gas Sensor Cartridges and one MultiSense Cartridge. Because the MultiSense Cartridge can have up to three gas sensors, the Aethair PRO can support monitoring of up to five gases (depending on configuration).

Gas Sensor Cartridge Calibration
Every Aethair PRO Gas Sensor Cartridge is calibrated and tested by an Aethair technician before it ships. Each sensor is first zeroed against a certified zero-gas reference to establish a stable baseline, then tested against a certified concentration of its target gas and verified to read within 10% of the reference.
During verification, each cartridge must demonstrate stable, linear, and sensitive response within acceptable limits before it is approved for field deployment.
Aethair recommends sending cartridges in for recalibration after one year.
