Description

The ATMOS 41 Gen 2 weather station is one of the first affordable, research-grade all-in-one weather station that fulfills all your weather monitoring needs but doesn’t restrain you when you want to make other measurements. All weather data (e.g., humidity, temperature, or atmospheric pressure) are transmitted over a single wire. That means you don’t have to use all of the ports on your data logger just for weather measurements. And, if you are using the ATMOS 41 weather station with our ZL6 data loggers, you have the flexibility to add any of our other sensors, like soil moisture.

Simple, compact, and connected

The ATMOS 41 weather station works seamlessly with the ZL6 for simple, plug-and-play atmospheric data logging and cloud-based data storage and management. You can set up an entire weather monitoring system without any complex wiring or programming. The ATMOS 41 weather station is a simple, compact, connected device with the flexibility to do more than weather measurements.

Second generation innovations

METER’s in-house research and development team have been working hard to make the ATMOS 41 Gen 2 more accurate, durable, and reliable than ever before. Wind speed can now be measured up to 60 m/s, meeting the requirements of even more industry standards, such as the IEC61724-1, making it ideal for applications such as utility-scale photovoltaic (PV) systems, and closer than ever to WMO guidelines.

The Gen 2 also provides a precipitation electrical conductivity (EC) measurement, more accurate precipitation measurements thanks to dual rain gauges, easier installation with built-in leveling bracket, and the option of MODBUS communication. Add in improved durability with more UV-resistant components, easier maintenance and serviceability, and a faster WMO-compliant sensor scan rate, and you’ve got the next generation in research-grade all-in-one weather stations.

The Weather Station, Reimagined

The ATMOS 41 weather station packages 12 weather sensors into a single, compact device for monitoring atmospheric conditions. It was designed for continuous deployment in harsh climates, such as sub-Saharan Africa and the extreme conditions around photovoltaic (PV) systems. There is only one moving part, eliminating virtually all failure points. No oiling or replacing bearings. Just reliability you can continue to count on.

More weather station sensors than other solutions

Most all-in-one weather stations give you the option to measure solar radiation or precipitation, but not both. The ATMOS 41 weather station provides both measurements in one device, so you never have to compromise.

Only one moving part

The one moving part on the Gen 2 is the tipping cup to provide better resolution at both high and low precipitation thresholds. Gold-plated pins measure each drop of rain using electric conductivity, ensuring a consistent 0.017 mm resolution for dew, rain, and heavy precipitation events. A sonic anemometer and internal accelerometer both ensure consistent, precise measurements without constant maintenance by insuring the stays level and motionless. Limiting the number of moving parts means the ATMOS 41 Gen 2 anemometer is also accurate at low wind speeds. It even has an accelerometer, so you’ll always know the sensor is level and you’re getting accurate data. And leveling the weather station is easier than ever with the new built-in leveling bracket.
