When you're choosing data acquisition recorders, the first question is whether you need a system-level front end or a self-contained logger. The DATAQ DI-720-USB is a data acquisition system with DI-5B amplifiers and a MESA interface. The Dickson TWP DicksonOne is a temperature/humidity data logger with an RTRH probe. Both are used and made in the United States, but they solve opposite parts of the problem.
Quick verdict
If you want a flexible acquisition front end to integrate into a larger setup, the DATAQ DI-720-USB gives you that base to work from, but it is sold as-is from a university surplus setting and has not been tested. If you want a self-contained environmental logger with WiFi/Ethernet options, the Dickson TWP DicksonOne is the more straightforward pick. The listed price spread is about $150, with the Dickson at $199.73 and the DATAQ at $349.99.
At a glance
| Product | Listed Price | Price Bar | What Stands Out |
|---|---|---|---|
| DATAQ DI-720-USB | USD 349.99 | System-level acquisition front end | |
| Dickson TWP DicksonOne | USD 199.73 | Touchscreen temperature/humidity logger |
Where each product wins
DATAQ DI-720-USB wins when you need a foundational acquisition system and are prepared to handle surplus-condition gear. That makes sense if you already have a measurement chain in mind.
Dickson TWP DicksonOne wins when you want a ready-to-use environmental logger with cloud-based access. That makes sense if you'd rather not assemble components.
Product notes
DATAQ DI-720-USB Data Acquisition System
The DATAQ DI-720-USB is the pricier, more system-oriented option. The DI-5B amplifiers and MESA interface point to a front end you can build into a custom data acquisition chain. If you're assembling your own measurement setup, that flexibility is the main reason to choose it. The flip side is risk: it's a used unit from a university surplus setting, sold as is, and the seller did not have the equipment to test it. It was dusty and may need further cleaning before it's usable. This is a sensible pick only if you're comfortable with surplus gear and ready to verify the unit yourself.
Dickson TWP DicksonOne Temperature/Humidity Logger
The Dickson TWP DicksonOne is the more turnkey option. It pairs a temperature/humidity logger with an RTRH probe, and the capacitive 8-inch touchscreen gives you customizable views and alarms. WiFi/Ethernet options make it easy to get data into your network, and the DicksonOne cloud service lets you check readings remotely. That combination is the reason to choose it if you want a dedicated environmental logger without assembling a system. The main limitation is the Dickson agreement: full functionality requires a separate agreement with Dickson that is not included. It's also a used unit arriving in its shown condition, with a 14-day guarantee. If the agreement fits your use case, this is the simpler path.
Final choice by use case
- Choose the DATAQ DI-720-USB if your priority is a system-level acquisition foundation and you're comfortable with surplus-condition gear.
- Choose the Dickson TWP DicksonOne if your priority is a self-contained logger and the Dickson agreement fits your workflow.
- For fixed environmental monitoring, the Dickson is the more direct tool. For custom measurement setups, the DATAQ system offers more room to adapt.
