Choosing between the Axon Instruments DigiData 1322A and the Madgetech PR1000-300-PSIG means deciding what kind of data acquisition recorder you actually need. The DigiData is a rack-mount, multi-channel digitizer geared toward controlled lab experiments, while the Madgetech is a compact, submersible pressure and temperature logger built for a single measurement point. They are both data acquisition recorders, but they solve different problems.
Quick verdict
If your work involves capturing many analog signals at once, the Axon DigiData 1322A is the right fit. If you need to log pressure and temperature in a pipeline, tank, or other field location, the Madgetech PR1000-300-PSIG is the more portable match. The two units barely overlap in how they should be used, so your measurement environment is the deciding factor.
Comparison at a glance
| Product | Price | Price comparison | Best fit |
|---|---|---|---|
| Axon Instruments DigiData 1322A | $249.99 | Bench-mounted digitizer with many parallel analog inputs | |
| Madgetech PR1000-300-PSIG | $699.00 | Submersible pressure and temperature logger |
Where the Axon DigiData 1322A wins
The DigiData 1322A is built around input density. It provides 16 analog input channels, 2 analog output channels, 16 digital input lines, and 16 digital output lines, and it captures signals with 16-bit resolution. That combination makes it a strong fit for electrophysiology and patch-clamp experiments, where you need to follow multiple biological signals at the same time. The SCSI computer interface and rack-mount configuration point to a permanent place on a lab bench rather than a portable field kit. If you can connect SCSI hardware to your computer, this unit can anchor a multi-channel acquisition setup.
Where the Madgetech PR1000-300-PSIG wins
The Madgetech PR1000-300-PSIG is the opposite approach: one rugged package that records pressure and temperature. With a 0 to 300 psig range and a 1/4-inch NPT fitting, it connects directly to pressurized systems, and its fully submersible design means it can sit in wet locations without housing concerns. The logger stands 4 inches tall and 1 inch in diameter, so it fits in tight spaces. It stores more than 1.3 million readings and works with the latest MadgeTech 4 software, making it a set-and-forget option for long-term monitoring.
Product notes
Axon Instruments DigiData 1322A 16-Bit Data Acquisition System
As a used rack-mount digitizer, the DigiData 1322A is a lab instrument. Its main reason to choose it is channel capacity: 16 analog inputs, 2 analog outputs, 16 digital input lines, and 16 digital output lines, all handled at 16-bit resolution. That lets you acquire a dense set of signals from one SCSI-connected unit, which is exactly what patch-clamp and biological signal work often requires. The limitation is the same legacy positioning: it is pre-owned and relies on a SCSI interface, so you should expect to integrate older hardware or an adapter into your computer setup. The unit powers on and the POWER and READY indicators illuminate, which is a useful confirmation that the hardware is live.
Madgetech PR1000-300-PSIG Pressure and Temperature Data Logger
The Madgetech logger is an easy choice when your monitoring point is a pressurized line or wet environment. The 0 to 300 psig range and 1/4-inch NPT fitting make it directly compatible with piping systems, and the submersible, 4-inch-tall body can be dropped into places a rack-mounted digitizer would never fit. It also stores more than 1.3 million readings, so you can leave it running for long stretches. The trade-off is specialization: it tracks pressure and temperature, not arbitrary voltage signals, so it is not a general-purpose acquisition front end. If you need many analog inputs at once, this logger will not fill that role.
Final choice by use case
For the lab bench, pick the Axon Instruments DigiData 1322A. Its channel-heavy architecture makes it the natural fit when you need to record multiple signals in parallel. For field installation and pressure/temperature monitoring, pick the Madgetech PR1000-300-PSIG. Its submersible body, NPT fitting, and long-running storage make it the better companion when you need one location tracked autonomously. Let the environment and the number of signals you need make the final call.
