Data acquisition recorders are easy to want and surprisingly hard to choose. The first fork is whether you need a ready-to-run kit with everything in the box or a compact module that drops into a bench setup with existing cabling. That is exactly the fork between the Pico Technology USB TC-08 Thermocouple Data Logger and the Vector GL1010 Compact Data Logger Module, and the price spread makes it a practical decision.
Quick verdict
Choose the Pico Technology USB TC-08 if you want an open-box kit that is essentially ready to plug in and log temperature and low voltage. Choose the Vector GL1010 if you prefer a used, compact logger module with a tested working condition and you are willing to supply the missing D-sub connection yourself.
Comparison table
| Consideration | Pico Technology USB TC-08 | Vector GL1010 |
| Price | USD 325.00 | USD 470.00 |
| Condition | New - Open box | Used |
| What's included | Logger unit, USB cable, software disc, installation guide, calibration certificate envelope, original box | USB cable only; no D-sub connection, no box |
| Form factor | Complete 8-channel thermocouple data logger kit | Compact data logger module |
Where each product wins
- The Pico TC-08 wins for getting started: the open-box kit comes with the logger, USB cable, software disc, installation guide, calibration certificate envelope, and original box, so there is no hunting for the missing pieces.
- The Vector GL1010 wins for users who already have the D-sub connection and just want a compact module that was used sparingly in a lab setting.
Product notes
Pico Technology USB TC-08 Thermocouple Data Logger (Model PP222)
The TC-08 is the lower-priced option in this pairing, and the open-box status means the outer boxes were opened for inspection while the logger unit, cables, and manuals remain clean and ready to use. This is a complete 8-channel thermocouple data logger kit that measures temperature and low voltage up to ±70 mV, and it connects over USB with PicoLog software. The kit includes the data logger, USB cable, software disc, installation guide, calibration certificate envelope, and original box, which makes it the easier path for a new setup. The main limitation is condition: this is open-box rather than an untouched sealed unit, so you are getting a like-new unit without the never-opened retail packaging experience.
Vector GL1010 Compact Data Logger Module
The GL1010 is the higher-priced listing here, and it comes as a used compact module rather than a kit. It was used sparingly in a lab setting, is described as being in great shape, and is in tested working condition. The package includes only the USB cable, so there is no D-sub connection and no original box. That makes the GL1010 a reasonable choice when you already have the D-sub connector and cabling on hand and only need the logger module itself. The limitation is also the missing pieces: if you are starting from scratch, you will have to source the D-sub connection and packaging separately, which adds friction that the Pico kit avoids.
Final choice by use case
- If you want the easiest route to temperature and voltage logging with a complete set of cables, software, and documentation, choose the Pico Technology USB TC-08 at $325.00.
- If you need a compact logger module for a lab setup where the D-sub connection already exists, the Vector GL1010 at $470.00 is the pick, as long as the used condition and missing box are acceptable.
