Automate your life

The ZL6 Pro data logger uses ZENTRACloud to automatically deliver near-real-time data wherever and whenever you need it, every 15 minutes (more often than the ZL6). Accessing data on ZENTRA Cloud speeds up your analysis by enabling you to correlate event factors, see important trends, or discover problems almost instantly, from the comfort of your own desk. This means your grad students can spend less time downloading data in the field, and more time generating research papers.

Plus, data are incredibly easy to distribute and share. Simply enter an email, and send an invitation. Your collaborators can instantly see what you see. The ZL6 Pro and ZENTRA Cloud allow you and others to review data the way you want, whether it’s in map format, short graphs, a list, or downloading to data-analysis packages. Not only that, the ZL6 Pro package comes with a free 3+ year subscription, so you don’t have to worry about renewals. And cloud data backup is now automatic so you don’t ever have to think about it.

You need to focus on data. Not distractions. Together, the ZL6 Pro and ZENTRA Cloud make it easy to connect all the critical tools you need to understand the soil-plant-atmosphere continuum, so you can analyze your data faster, and at a much deeper level.

Get connected

The ZL6 Pro connects up to six different types of multi-parameter METER sensors, so you can potentially monitor a host of different parameters, such as weather, soil moisture, and soil water potential, all at the same time, giving you deeper insight into what’s going on at your site. We’ve also integrated barometric pressure to eliminate the need to install extra sensors. And because everything is plug and play, you don’t have to be an expert at wiring or programming.

Peerless design—world-class reliability 

We engineered the ZL6 data logger to be extremely robust and low maintenance, so you can almost forget about your data logger completely. The ZL6’s integrated solar charging panel means there’s hardly any power maintenance required. An IP56-rated enclosure designed for shedding rain makes sure water doesn’t get in. More secure cable handling ensures sensor cables don’t get yanked out. A hidden antenna limits breakage. And we’ve added fully round clasps and hinges that won’t break. Plus, free yearly tune-ups for 3 years and an increased 3-year warranty mean you no longer have to worry about upkeep.
