Meter ATMOS 22 Ultrasonic Anemometer

Meter – ATMOS 22 Ultrasonic Anemometer

The ATMOS 22 was designed without moving parts, meaning there’s never any mechanical wear. No oiling or replacing bearings. And no recalibration required. Just reliability you can continue to count on.

Not only does its ultra-low power consumption make it ideal for long-term, remote installations, but its compact size makes it small enough to deploy inside canopies. And instead of having to make field visits to collect data and check sensor and system functions, you can monitor information in real time and download data using any internet-connected device by connecting the ATMOS 22 to a ZL6 data logger. Which not only saves you time, but provides worry-free operation and peace of mind.
