low cost, easy to use, data logger with modem


The ZL6 is a stand-alone data logger unit that is low cost and easy to use.

It is a specialised data logger designed to supported the METER Group range of sensors including TEROS, ATMOS and PHYTOS models.

Features of the ZL6 data logger include:

  • No programming - simply connect sensors and you're done;
  • 6 channels - measure and monitor a range of parameters by choosing up to six METER Group sensors;
  • Built-in battery and solar panel for easy power supply management;
  • Built-in modem for accessing data over the internet (add-on module);
  • Access data via ZENTRA Cloud online data management software; and
  • IP56, or NEMA 3R, environmental and weather proof enclosure.


free software for configuration and downloading data

The ZENTRA Utility app is a free software that allows you to easily interact with the ZL6 data logger.

By following GUI promps, you can configure your sensors, set logging intervals, view data in real-time, download data to .csv file, and more.

The ZENTRA Utility app operates via direct connection with a USB cable or wirelessly via a Bluetooth connection.


power management made easy

One of the greatest challenges in field work is power management. The ZL6 has made power management easier than ever with its built-in solar panel and battery system

The ZL6 data logger has a solar panel embedded in its enclosure. Inside the enclosure are 6 x AA rechargeable batteries (nickel-metal hydride, NiMH).

Battery capacity, without solar recharging, can be as long as 9 to 12 months.


compatible sensors

The ZL6 data logger is only compatible with the METER Group range of sensors. Third-party sensors are not supported by the ZL6 data logger.

Connecting the METER Group range of sensors is easy - simply connect via the stereo plug, set sensor type in the ZENTRA Utility app, and you're done!

No programming is required.
