Two very different approaches to data acquisition recorders sit on either side of this comparison. The DATAQ DI-720-USB is a general-purpose acquisition system, while the Madgetech PR1000-300-PSIG is a dedicated pressure and temperature logger. That difference matters more than the $349.99-to-$699.00 price gap. If you need a flexible signal-conditioning front-end and can live with a used unit, the DATAQ targets that need. If you want a new, self-contained logger for pressure and temperature, the Madgetech is the more direct fit.
Quick Verdict
The Madgetech is the easier recommendation when the job is pressure and temperature logging and you want a unit that is ready to work. The DATAQ is the more flexible alternative for buyers building a multi-signal acquisition setup who are comfortable with a used, AS-IS unit.

Where Each Product Wins
The DATAQ DI-720-USB wins when you want an acquisition platform rather than a single-purpose logger. It pairs a USB acquisition main unit with signal-conditioning hardware, making it a modular starting point for projects that need multiple signal types through one system. It also suits buyers who prefer to supply their own signal sources and do their own preparation.
The Madgetech PR1000-300-PSIG wins when the measurement job is already defined. Pressure and temperature logging is what it does, and its new condition plus submersible build make it a straightforward pick for locations where a benchtop system would not be practical.
Product Notes
DATAQ DI-720-USB Data Acquisition System w/ DI-5B Amplifiers & MESA Interface
Buyers who think in terms of signal chains will appreciate what this system represents. The DI-720-USB unit connects with DI-5B amplifiers and a MESA interface, which points to a modular acquisition setup rather than a fixed-sensor logger. That makes it a candidate when you want to condition and capture multiple types of signals through one front-end. The trade-off is equally clear: this is a used unit sold AS IS, and it was not tested with proper equipment. It was also dusty when found and may need further cleaning. If you have the patience to bring a second-hand system back to working order, the DATAQ gives you a wider path for custom signal conditioning; if you need plug-and-play confidence, this one involves more hands-on work.
Madgetech PR1000-300-PSIG Pressure and Temperature Data Logger, 0 to 300 psig
For pressure and temperature logging, this logger is the more complete package. It covers 0 to 300 psig, includes a 1/4 NPT fitting, and its fully submersible design lets it go where a bench system cannot. The internal temperature sensor covers -40 to 176°F, and the unit stores more than 1.3 million readings. It also works with MadgeTech 4 software, which makes it convenient to configure logging runs and pull collected data. The limitation is specialization: this is a pressure-temperature logger, not a broad multi-channel acquisition front-end. If your project revolves around those two measurements, it is a strong fit; if your needs are more general, the DATAQ's flexible front-end may be the better match.
Final Choice by Use Case
Choose the DATAQ DI-720-USB when you are assembling a signal-conditioning setup and can work with a used, AS-IS unit that may need cleaning. Choose the Madgetech PR1000-300-PSIG when you need a self-contained pressure and temperature logger for long logging sessions.
