ZL6-B Basic
low cost, easy to use, data logger
overview
The ZL6-B Basic 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-B 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;
- AA-sized batteries for easy power supply management; and
- IP56, or NEMA 3R, environmental and weather proof enclosure.

ZL6 versus ZL6-B Basic
The ZL6-B is similar to the ZL6 model but with a few important differences. These include:
- The ZL6-B does not contain a modem and cannot send data to the internet;
- The ZL6-B has a fixed logging interval of 1 hour; and
- Data must be downloaded manually with the USB cable and the freely available ZENTRA Utility software.
free software for configuration and downloading data
The ZENTRA Utility app is a free software that allows you to easily interact with the ZL6-B data logger.
By following GUI promps, you can configure your sensors, 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.

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.
