Choosing a data acquisition recorder can be tricky because the term covers everything from multi-channel electrical loggers to GPS telemetry units and touchscreen temperature monitors. The real question is not which device wins an overall label but which one fits the signals you need to capture, the environment you're working in, and the way you want to review the data. Here are four recorders with listed prices ranging from $129.99 to $450, each with a different measurement focus.
Quick Take
The Graphtec Midi Logger GL220 is a 10-channel electrical logger. The Racebox Micro is a compact GPS speed meter and telemetry logger. The Pico Technology TC-08 is an 8-channel thermocouple data logger. The Dickson TWP is a touchscreen environmental data logger. Use the sections below to match each option to your priorities.

Product Notes
Graphtec Midi Logger GL220
The Graphtec Midi Logger GL220 is a 10-channel data logger that covers voltage, current, power, and pulse/event measurements, making it a solid choice if you need to monitor multiple electrical signals from one device. Its USB interface keeps connection to a computer straightforward for later analysis. That said, this particular unit is listed as used, so you're receiving a pre-owned device rather than a fresh-out-of-box unit. If your work demands consistent multi-channel electrical logging and you're comfortable with a used instrument, this is a strong fit.
Racebox Micro GPS Speed Meter & Telemetry Data Logger [BOX001
The Racebox Micro is a compact GPS speed meter and telemetry data logger with a 25Hz GNSS receiver and measurement precision of ten centimeters. It supports both the RaceBox Protocol and NMEA over Bluetooth, plus built-in storage for standalone logging. That makes it a good match for lap timing, drag runs, and telemetry projects where you want small size and high update rate. The tradeoff is that this device is built around GPS-based speed and position data rather than general-purpose temperature or voltage logging, so it won't replace a multi-channel lab logger for electrical measurements.
Pico Technology USB TC-08 Thermocouple Data Logger (Model PP222) - New/Open Box
This Pico Technology TC-08 kit is an 8-channel thermocouple data logger that measures temperature and low voltages up to ±70 mV, and connects over USB to PicoLog software. The open-box condition means the outer packaging has been opened for inspection, while the data logger, USB cable, software disc, installation guide, factory calibration certificate, and original box are included. If your application centers on thermocouple-based temperature logging, the TC-08 is directly on point. The main limitation to weigh is the open-box packaging, so you're not receiving a factory-sealed product; however, the contents themselves are described as clean and maintained.
DICKSON TWP DICKSONONE TOUCHSCREEN TEMPERATURE/HUMIDITY DATA LOGGER & RTRH PROBE
The Dickson TWP combines a capacitive 8-inch touchscreen, temperature/humidity logging, and an RTRH probe in one unit. It offers WiFi/Ethernet options and AC power, and it connects to cloud-based DicksonOne for remote data access. The touchscreen interface is a helpful feature if you want on-device display and control rather than a purely software-centered logger. One thing to keep in mind is that full DicksonOne functionality requires a separate agreement with Dickson, and that agreement is not included with this used unit. If you're prepared to manage that requirement, the TWP brings a display-first approach to environmental monitoring.
Final Recommendation by Use Case
- For multi-channel electrical logging, the Graphtec Midi Logger GL220 is the option to consider; its used condition is the trade-off.
- For speed and telemetry work, the Racebox Micro is the compact pick.
- For low-voltage temperature logging, the Pico Technology TC-08 is the USB-connected choice with an included calibration certificate.
- For environmental monitoring with an RTRH probe, the Dickson TWP offers on-device control, provided you can arrange the DicksonOne agreement.
