Choosing a data acquisition recorder often comes down to how much capability you need versus how much you want to spend. This head-to-head puts a 2-slot Keithley mainframe against a lower-priced DATAQ Instruments system, and the right pick depends on whether expansion and multimeter-style features are worth the larger investment. You'll want to weigh channel flexibility and measurement style before you decide.
Quick verdict: Pick the Keithley DAQ6510 when you want a dual-purpose recorder with multimeter-system capabilities and room to expand. Pick the DATAQ Instruments DI-500-16 when you want a lower-priced entry into data acquisition.
| Product | Listed Price | Price Indicator | Condition | Country of Origin |

Where each product wins
Where the Keithley DAQ6510 wins: The DAQ6510 is the better match when your work combines data acquisition with multimeter-style measurement. The DMM6500 Multimeter System component of the title points to that dual role, and the unit is positioned as a more expandable mainframe. If you want one instrument to serve as both recorder and meter, this is the direction to lean.
Where the DATAQ Instruments DI-500-16 wins: The DI-500-16 takes the more budget-conscious side. It carries the lower price in this pairing, and that lower entry point gives you more flexibility to spend on the rest of your test setup.
Keithley DAQ6510 Data Acquisition DMM6500 Multimeter System
The DAQ6510 is the feature-forward option for a data acquisition recorder. Its title combines a data acquisition system with the DMM6500 Multimeter System, so it appeals to engineers who want a single instrument for logging and meter-style readings. The 2-slot architecture is another practical reason to consider it: you can add modules later and expand the system without buying a new mainframe. The limitation is the price; at the top of this comparison, it asks for a larger upfront commitment. If your measurement needs are still growing, that higher entry cost can be justified by the expandability and dual-purpose design.
DATAQ INSTRUMENTS DATA ACQUISITION SYSTEM DI-500-16
The DATAQ Instruments DI-500-16 is the lower-priced route into data acquisition recorders, and its United States origin is a plus if provenance matters. The item is described as a used system, so include a pre-purchase inspection in your plan. The title frames it as a data acquisition system, which fits buyers who already have a separate meter and just need to capture data. Because the asking price is lower, you keep more budget for sensors, connectors, or other components of your test chain. It is the practical pick when you want recording capability at a lower upfront cost.
Final choice by use case
- Dual-duty measurement: Choose the Keithley DAQ6510 if you want data acquisition and multimeter-system features in one unit and expect your setup to grow.
- Budget-focused recording: Choose the DATAQ Instruments DI-500-16 if you want a lower-cost data acquisition recorder.
