Not all data acquisition recorders are interchangeable, and choosing the wrong one usually means paying for a connection type or measurement range you don't need. The better question to ask is: what signal do you need to capture, and where does that capture need to happen? The four recorders here cover very different worlds: a USB thermocouple logger for a PC bench, an industrial recorder/controller for a process line, a GPS telemetry logger for vehicles, and a touchscreen station for facility monitoring. Prices span $129.99 to $416.04, and the spread is tied to what each unit is asked to do.
Quick Take
- USB thermocouple logging: Pico Technology USB TC-08 (Model PP222)
- Industrial recording plus control: Eurotherm Nanodac
- GPS speed and telemetry: Racebox Micro
- Touchscreen temperature logging with remote probe: Dickson TWP

Product Notes
Pico Technology USB TC-08 Thermocouple Data Logger (Model PP222)
The Pico Technology USB TC-08 (Model PP222) is a natural bench logger in this group: one USB connection, eight thermocouple channels, and software-based data capture. It also handles low voltage up to ±70 mV, so it is useful when your temperature measurements sit on top of a small electrical signal. The kit comes in new/open-box condition, and the contents have been inventoried and kept clean in the original packaging, with the USB cable, software disc, installation guide, and factory calibration certificate envelope included. The trade-off is its signal range: ±70 mV is fine for thermocouple and millivolt-scale work, but it is not a high-voltage recorder. If your main job is thermocouple channels on a laptop, this is the unit to start with.
Eurotherm Nanodac Invensys Recorder Process Controller Data Logger Ethernet USB
The Eurotherm Nanodac is the process-oriented option here. It is a paperless recorder and process controller with a color display, a USB host port, Ethernet communication, multiple universal analog inputs, relay outputs, and built-in data logging. That combination makes it appealing if you need to control a process and record its behavior in one instrument. It was removed from a working system, so expect used condition with light scratches and minor marks on the bezel. In many plant environments that cosmetic wear is a minor factor, but it is still a used unit rather than a factory-fresh one. If your application is industrial process control, this is the unit to weigh against a simple logger.
Racebox Micro GPS Speed Meter & Telemetry Data Logger
The Racebox Micro sits at the other end of the data acquisition spectrum. It is a GPS speed meter and telemetry logger, and its 25Hz GNSS receiver gives it ten-centimeter precision for lap and drag timing. The unit supports Bluetooth output in both RaceBox Protocol and NMEA, includes built-in storage, and works standalone, which makes it a useful building block for DIY telemetry projects with the API documentation. It is compact and comes as a new unit, and its focus is position, speed, and timing rather than wired process signals. It is built around GPS/GNSS rather than wired analog inputs, so keep it in the speed-and-position lane. If your data is about where the vehicle is, this is a strong match; if your data comes from sensors on a bench, it is not.
Dickson TWP DicksonOne Touchscreen Temperature/Humidity Data Logger & RTRH Probe
The Dickson TWP is the touchscreen answer for temperature monitoring with a remote probe. Its 8-inch capacitive display gives you customizable views and alarms, and the included RTRH probe extends the sensing point away from the logger body. WiFi/Ethernet options and AC power make it feel like a permanent station, and the DicksonOne cloud service is the intended way to reach the data from elsewhere. The biggest limitation is that full DicksonOne functionality requires a separate agreement with Dickson, and that agreement is not included with this used unit. It also arrives with whatever wear is visible in the photos. If you want a large-display logger with a remote probe and are comfortable managing the DicksonOne account yourself, this is a practical used pick.
Final Recommendation by Use Case
Put the decision back in your own workflow:
- If you need eight thermocouple channels and low-voltage temperature logging from a PC, the Pico Technology USB TC-08 is the clear fit.
- If you need a recorder that also controls a process, the Eurotherm Nanodac brings Ethernet, USB, analog inputs, and relay outputs together.
- If you are timing laps or building a GPS telemetry setup, the Racebox Micro is the focused, compact choice.
- If you want a touchscreen logger with a remote probe for a facility, the Dickson TWP fits, as long as you account for the DicksonOne agreement.
The right data acquisition recorder is the one that matches your signal type, your environment, and your workflow. Match the tool to the job, and the numbers will follow.
