Advanced Cloud Data Logger

Maximize Your Data Productivity

With the advent of big data, you can’t afford to 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. Welcome to the new ZL6 universe.

This data logger breaks new barriers, so you can too

With the ZL6 data logger, there are no limits. That’s because we’ve reinvented the entire METER data logging system so the ZL6 can be your ultimate research partner. Easier, more advanced, and more robust, the ZL6 data logger introduces cloud-based data delivery, Bluetooth® configuration, GPS, and integrated metadata, all of which simplify and speeds up the process of data collection, management, and sharing. It does all 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 your grad students can spend less time downloading data in the field, and more time generating research papers. 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.

Data are transferred to the Cloud in two different ways, depending on your chosen configuration. Choose between hardware that allows 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. Simply enter an email, 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 in map format, short graphs, a list, or downloading to data-analysis packages.

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.

Uncomplicated. Almost unbreakable. And unbelievable.

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.
