Choosing between two used data acquisition recorders can feel like a trade-off between price and capability. One is a no-nonsense logger, and the other combines recording with controller features for connected setups. Your decision comes down to whether you need simple data capture or a unit that can also communicate with other equipment.
Quick Verdict
If your priority is a lower upfront cost and you just need to log data, the ThermoFisher DataTaker DT82I is the practical pick. If your work involves remote communication and control, the Eurotherm Nanodac is worth the larger investment.

Product Notes
ThermoFisher DataTaker DT82I Series 3 Industrial Data Logger w mount
The ThermoFisher DataTaker DT82I Series 3 is a straightforward industrial data logger that comes with a mount. It is priced at $249.99, making it the more affordable of the two, and the unit is described as working well and complete with what is shown. That makes it an easy choice when your main need is capturing data without paying for control capabilities you won't use. The limitation is that its listed role is data logging; if you need process-control outputs, the Eurotherm is the unit positioned for that function. For a no-frills logging setup, the DT82I is the practical pick.
Eurotherm Nanodac Invensys Recorder Process Controller Data Logger Ethernet USB
The Eurotherm Nanodac is a different kind of device: it is a paperless recorder and process controller in one. At $416.04, it is the higher-priced option, but it brings Ethernet communication, a USB host port, multiple universal analog inputs, relay outputs, and a color display. If your data acquisition work also involves controlling a process or retrieving records over a network, this unit gives you the tools to do that. The unit comes from the United Kingdom and shows normal cosmetic wear, including light scratches and minor marks on the bezel, which is an acceptable trade-off if these features are what you need. The limitation is the price: it costs $166.05 more than the DataTaker, so it is a bigger investment for buyers who only need basic logging.
Final Choice by Use Case
Choose the ThermoFisher DataTaker DT82I if you want the lower price for straightforward data logging. Choose the Eurotherm Nanodac if you need connected control capabilities and don't mind the higher price.
