What are inaccurate predictions costing you?

Ag Weather Networks

Low quality data can skew your modeling predictions, causing you to act at the wrong time or irrigate incorrectly. METER weather instruments are developed, rigorously tested, and supported by scientists—so you can get the high quality measurements you need, at the site you care about, for a price you can afford.

Education guides45 min read

For accurate models, you need temperature data from your field or orchard, not regional data from miles away. That's why we created the ATMOS 41—an affordable, accurate way to capture in-field temperature measurements. Setup is incredibly easy. No complicated maintenance. Just reliability and quality data you can continue to count on.

Forget spreadsheets. What if your GDD models could be automated? With the ATMOS 41 and ZENTRA Cloud software, they can. ZENTRA Cloud works with the ZL6 to aggregate all your data in one easy place, graph them in near-real time, and even automate common environmental models.
