Aura1 · Ambient sensor
Made for the balance
The air at the balance, read at every weighing
Temperature, humidity and barometric pressure next to your balance, read by GasCatena at every weighing and reported with the preparation.
Coming early 2027
Connection
Plug in and weigh
Compact and powered over USB-C, without battery or radio: a standard USB device that needs no driver. Select it once in GasCatena, under Settings → Sensors, and it is read at every weighing. Your own software can read it the same way.
Statistics
Every value with its spread
Each value is the average of a series of independent readings taken by your computer, 16 by default, reported with its standard deviation and number of readings: ready for a type A uncertainty evaluation. No smoothing, no filters.
Calibration
Traceable to the SI
Supplied uncalibrated as standard, with calibration as an option: by Qualimetric in accordance with ISO/IEC 17025, or by a calibration laboratory of your choice.
Weighing
Air-buoyancy correction
Temperature, humidity and pressure at the moment of weighing, for the air density and the buoyancy on the cylinder.
Quality
ISO/IEC 17025 records
The ambient conditions of every weighing recorded with the preparation, where they influence your results.
Independent
Stand-alone and secure
No cloud, no account, no radio: a USB device on your own computer.
