Easy DAQ and onboard data logging

Get all your data acquisition (DAQ) requirements fulfilled with the Zen Datalogger. It logs data onto a 1GB micro SD card, so you can physically take your data with you or route it to other hardware.

Data visualization and graphing helps you understand your data

If logging data is vital to your application then you’ll know that interpreting that data is just as vital. The Zen Datalogger gives you a simple way (via WorkBench software) to plot graphs and visualize your data for a better understanding of your results.

“We’ve had a Define data logger in operation for more than a year now and it has been running flawlessly since the day of commissioning.” Columbus Steel

Enjoy the flexibility of universal inputs

Like its predecessor (ZEN-16) the Zen Datalogger accepts TC, RTD, mA, mV, V, Frequency and Counter and shares many of its capabilities. This means you can reduce the number of separate instruments you need for your application, keeping things simple for maintenance and troubleshooting.
