Deciding between two used data acquisition recorders can feel like comparing a laboratory instrument with a factory-floor controller. The Axon Instruments DigiData 1322A and the Eurotherm Nanodac Invensys Recorder both capture signals, but they serve different environments. This head-to-head breaks down what each one actually offers so you can match the recorder to your work. One is a digitizer with a clear channel count and a scientific design; the other is a process controller with network connectivity and a broader industrial feature set.
Quick Verdict
If your work is research-grade digitizing, the Axon DigiData 1322A is the more direct fit: it spells out a defined channel structure, all at $249.99. If you need a process recorder with modern networking, the Eurotherm Nanodac brings connectivity and data logging for $416.04. The Axon wins on price and channel clarity; the Eurotherm wins on networking and process-control features. In short, choose the Axon when you need to know exactly how many inputs you're working with, and choose the Eurotherm when you want a network-connected process logger.
Comparison Table
| Product | Listed Price | Headline Features |
|---|---|---|
| Axon Instruments DigiData 1322A | USD 249.99 | 16-bit resolution, 16 analog input channels, SCSI interface |
| Eurotherm Nanodac Invensys Recorder | USD 416.04 | Color display, Ethernet, USB host, relay outputs, data logging |
Where Each Product Wins
Axon DigiData 1322A: If your application centers on multi-channel biological signals and you want a spec sheet that tells you exactly how many inputs you have, the DigiData 1322A is the stronger fit. Its defined channel structure gives you confidence before you start wiring. For a research bench where reproducibility depends on knowing the input count and resolution, this clarity is a real advantage.
Eurotherm Nanodac: If you're managing an industrial process and want to pull data off the unit from across the room or over a network, the Nanodac's connection options are the deciding factor. Its process-control features make it more than just a logger. For a plant floor or a lab that needs to archive data remotely, the connectivity focus is a clear advantage.
Product Notes
Axon Instruments DigiData 1322A 16-Bit Data Acquisition System SCSI USA
The Axon DigiData 1322A is built for scientific data acquisition, and its spec sheet is direct: 16 analog input channels and 16-bit resolution are stated up front. For a used unit, that level of detail makes planning your signal connections easier. The SCSI interface is a sign of its lab-oriented design, and the rack-mount configuration suits a permanent setup. The unit powers on with the POWER and READY indicators illuminated, per the listing. The strongest reason to choose it is that clear channel structure-if you need a known number of inputs for patch-clamp or biological signal work, you don't have to guess. The main limitation is the SCSI connection: you'll likely need an adapter or an older computer to talk to it, which is worth budgeting for.
Eurotherm Nanodac Invensys Recorder Process Controller Data Logger Ethernet USB
The Eurotherm Nanodac is a paperless recorder and process controller that emphasizes connectivity and process visibility. Ethernet and a USB host port are the headline features, which make transferring logged data and connecting to a network straightforward. It also lists relay outputs and a color display, so it can participate in control tasks. The unit was removed from a working system, so it shows normal cosmetic wear including light scratches on the bezel. The reason to choose it is that network-and-USB combination, which fits modern industrial setups. The trade-off is the used condition: if you expect a pristine faceplate, the visible scuffs and marks may be a letdown.
Final Choice by Use Case
- If you're doing electrophysiology, patch-clamp, or multi-channel biological recording where every input channel matters, the Axon DigiData 1322A is the more aligned choice. The explicit channel configuration lets you design experiments without ambiguity.
- If you're managing an industrial process and need a recorder that fits a networked workflow, the Eurotherm Nanodac is the one to put on your panel. Its connection options are aimed at exactly that scenario.
