Buying a data acquisition recorder comes down to matching the instrument to the signal you're chasing. These four systems span a wide price range, and each one is built for a different job. Before you compare specs, decide whether you're logging energy data over a network, capturing patch-clamp recordings, or running a bench multimeter that can also acquire data.
Quick Take
- Patch-clamp work with pClamp: Axon Instruments Digidata 1320A.
- Energy monitoring over IP: Obvius A8810-0 AcquiSuite.
- Bench multimeter plus data acquisition: Keithley DAQ6510.
- Modular lab setups: iWorx Systems IX/228.

Product Notes
Keithley DAQ6510 Data Acquisition DMM6500 Multimeter System (USD 1,600.00)
The DAQ6510 pairs a DMM6500 multimeter with a data acquisition system, so it's the closest thing here to a general-purpose bench recorder. It's a used unit with two slots and a Country of Origin of China. If you want one instrument that can handle both multimeter-style readings and logging, this is the unit to weigh against the specialized options. The obvious limitation is the price: at USD 1,600.00 it sits at the higher end of this group, and you're paying for that dual-function design.
Axon Instruments Digidata 1320A 16-Bit Data Acquisition System for pClamp Lab (USD 99.99)
This is the specialized electrophysiology pick. The Digidata 1320A is compatible with Axon pClamp software, including Clampex and Clampfit, and the intended use is biological laboratory work. At USD 99.99, it's the least expensive unit in the comparison, which makes it a direct way into pClamp-based recording if the used condition works for you. The limitation is the narrow focus: this is not a general-purpose data recorder. It is marked Custom Bundle: No, so expect the system on its own rather than a package of extras.
Obvius A8810-0 AcquiSuite Embedded Data Acquisition System With Manual (USD 500.00)
The Obvius A8810-0 is the middle-priced option at USD 500.00 and the only one listed as New - Open box. Its job is energy monitoring: it is tied to ModBus/TCP/Ethernet and IP-based applications such as enterprise energy management, demand response, and smart grid programs. It comes with a manual, but the 24V power supply is not included, so that's a real setup consideration. Choose this one when your data lives on a network rather than on a bench. The limitation is the opposite of the Keithley: this is an embedded hub for energy and building data, not a multimeter-style instrument or a lab front-end for analog physiology signals.
iWorx Systems IX/228 Data Acquisition System Module Part IWX/228 (USD 1,725.24)
The iWorx IX/228 is the priciest listing at USD 1,725.24, and it's also the one with the most caveats. It is a used unit acquired in a state surplus sale, the prior usage history is unknown, and it powers up but has not been further tested. It comes as pictured with no other accessories. If you're building an iWorx-based modular lab setup, this module could be the missing piece, but the unknown history means it's not a no-surprises instrument. Use this pick only when the iWorx platform is already your direction and you're comfortable with the unit's described condition.
Final Recommendation by Use Case
- If your daily work is patch-clamp recording in pClamp, start with the Axon Digidata 1320A.
- If you're collecting energy or building-management data across a network, the Obvius A8810-0 is built for that.
- If you need a bench instrument that also functions as a multimeter, the Keithley DAQ6510 is the general-purpose choice.
- If you're committed to the iWorx modular platform and can accept a used module with an unknown service history, the IX/228 completes the set.
