Maximize your data productivity
With the advent of big data, you can’t be constantly fussing with complex programming, installation headaches, downloads, data gaps, or maintenance. You need a data logger that puts near-real-time data at your fingertips—whenever, wherever, and however you want it—so you can maximize your paper output.
This data logger breaks new barriers, so you can too
With the ZL6 data logger, there are no limits. Easier, more advanced, and more robust, the ZL6 data logger offers cloud-based data delivery, GPS, integrated metadata, and configuration via Bluetooth® using the ZENTRA Utility app, all of which simplify and speed up the process of data collection, management, and sharing. It does the legwork for you, so you can spend more time being a data visionary.
Less work. More discovery.
The ZL6 data logger uses ZENTRA Cloud to deliver near-real-time data wherever and whenever you need it. This means you can spend less time downloading data in the field and more time generating results. Accessing data on ZENTRA Cloud speeds up your analysis by enabling you to correlate event factors, see important trends, or discover problems almost instantly, all from any location with an internet connection.
Choose between hardware that allows data upload via cell service or via Wi-Fi. Whichever you choose, data can also be downloaded directly via USB. Whether your site is within reach of cell service or relies on a local internet connection, ZL6 operates where you work, sending data effortlessly to ZENTRA Cloud for easy access and analysis.
Plus, data are now incredibly easy to distribute and share using ZENTRA Cloud. Simply enter an email address and send an invitation. Your collaborators can instantly see what you see. The ZL6 data logger and ZENTRA Cloud allow you and others to review data the way you want, whether it’s an annotated map, short graphs, a list, or downloaded to data-analysis packages.
Uncomplicated. Almost unbreakable.
We engineered the ZL6 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.
Good at everything, so you don’t have to be
With the ZL6 data logger, you no longer have to be a specialist in every discipline. Using the ZL6 is like having a meteorologist, a soil physicist, and more at your disposal, allowing you more time to focus on your specialty. How? The ZL6 data logger connects up to six different types of METER sensors, so you can monitor different parameters, such as weather, soil moisture, and soil water potential, all at the same time, giving you deeper insight. 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.
You’ve got research. We’ve got you.
Want each of your grad students to write one more peer-reviewed paper? Now they can. With the ZL6, you can focus on data, not distractions. Together, the ZL6 data logger 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.
