Choosing a data acquisition recorder often means deciding between a dedicated logger and a separate process controller. The Eurotherm Nanodac combines both roles in one panel-mounted instrument. This used unit, priced at USD 416.04, combines recording and control in a single device. For a bench or panel project where you need to capture process signals and act on them, that combination is the main reason to stop and read on.

This Nanodac is a genuine Eurotherm unit manufactured in the United Kingdom. It was removed from a working system, so it arrives in used condition with normal cosmetic wear. That means light scratches and minor marks on the bezel are part of the deal, and you receive the exact item shown in the photos. The core feature set is what makes it interesting: a color display for viewing process values, a USB host port for getting data off the unit, Ethernet communication for network integration, multiple universal analog inputs for a range of signal types, relay outputs for control tasks, and built-in data logging to capture what the inputs see.
#### Quick Verdict
If you need a paperless recorder that can also perform process-control duties, this Nanodac is a strong used option. The dual-purpose design can simplify a panel, and the connectivity options give you flexible ways to move data around. The main catch is the used condition: this is not a fresh-out-of-the-box instrument, and visible signs of previous service come with the territory.
#### Who It Suits
This is best suited to someone who already works with industrial instrumentation and is comfortable evaluating used gear by its visible condition. It fits projects where you want to replace a chart recorder and a controller with one unit, or where you need to capture analog signals and trigger outputs without adding a separate PLC or PC-based system. It is less ideal for someone who wants a brand-new, untouched panel instrument.
#### What Stands Out
The standout is the dual personality of the device. As a recorder, it offers a color display and data logging across multiple universal analog inputs. As a controller, it provides relay outputs and acts as a process controller. The USB host port is a practical touch for pulling recorded data to a USB drive, and Ethernet adds a way to integrate the recorder into a wider network. For a used unit, you are getting a compact industrial package that would otherwise require several separate components.
#### Meaningful Trade-offs
The most obvious trade-off is cosmetic. The unit shows light scratches and bezel marks from previous use, which is normal for working industrial hardware but matters if the device will sit somewhere visible. Another trade-off is that you are buying a single used item, so the exact condition shown in the photos is what you can rely on. The feature set is solid, but the used nature means accepting some wear.
#### Bottom Line
For someone looking for a data acquisition recorder with built-in process control, the Eurotherm Nanodac is worth considering at USD 416.04. It combines recording and control in one chassis, so you avoid needing a separate logger and controller. Accept the wear and the visible signs of use, and it becomes a practical choice for industrial and lab-style setups that need both functions without taking up extra panel space.
