Choosing between these two data acquisition recorders really comes down to how you want to collect data. The Pico Technology USB TC-08 is a PC-focused thermocouple and low-voltage logger with a USB connection and PicoLog software. The Eurotherm Nanodac is a used industrial process controller and paperless recorder with a color display, Ethernet, USB host port, universal analog inputs, and relay outputs. Their listed prices are $325.00 and $416.04, so the buying decision is about workflow first and the $91.04 price gap second.
Quick verdict
If your job is thermocouple temperature and low-voltage logging from a computer, the Pico Technology USB TC-08 is the more direct tool: plug it into USB and track eight thermocouple channels. If you need an industrial panel-friendly recorder that can handle control duties, the Eurotherm Nanodac is the stronger candidate, provided you accept used condition.
At a glance
| Product | Listed Price | Best For | Watch Out |
|---|---|---|---|
| Pico Technology USB TC-08 | $325.00 | Thermocouple temperature and low-voltage logging over USB with included PicoLog software and calibration certificate envelope | New open-box condition |
| Eurotherm Nanodac | $416.04 | Industrial process recording and control with color display, Ethernet, USB host, universal analog inputs, and relay outputs | Used condition with cosmetic wear |
Where each wins
Choose the Pico Technology TC-08 when you want a clean, PC-connected logger kit for temperature and voltage. The open-box set includes the data logger, USB cable, software disc, installation guide, and factory calibration certificate envelope, so you have everything needed to start logging right away.
Choose the Eurotherm Nanodac when you need a self-contained industrial instrument with a color display and wired connectivity. It was removed from a working system, and its Ethernet, USB host, multiple universal analog inputs, relay outputs, and process control functions make it a different class of tool than a simple USB logger.
Pico Technology USB TC-08 Thermocouple Data Logger (Model PP222)
The Pico Technology TC-08 is a complete 8-channel thermocouple data logger kit with a USB interface and PicoLog software. It measures temperature and low voltages up to plus or minus 70 mV, making it useful for bench work where you want high-resolution readings without a panel-mounted instrument. The kit arrives as a new open-box unit: the outer boxes have been opened for inspection, but the contents are described as clean and meticulously maintained. It includes the logger, USB cable, software disc, installation guide, factory calibration certificate envelope, and original box. The practical limitation is the open-box condition; beyond that, this is a USB-centric logger, so a shopper who wants control outputs or network communication will find those capabilities in the Eurotherm Nanodac.
Eurotherm Nanodac Invensys Recorder Process Controller Data Logger Ethernet USB
The Eurotherm Nanodac is a genuine paperless recorder and process controller manufactured in the United Kingdom, pulled from a working system and listed in used condition. It bundles a color display, USB host port, Ethernet, multiple universal analog inputs, relay outputs, and data logging into one panel-style instrument. That makes it a fit for industrial setups where you want the recorder itself to be the hub, not just a peripheral connected to a PC. The obvious limitation is cosmetic condition: it has light scratches and minor marks on the bezel from previous use, and the listing makes clear you are getting the exact unit shown in the photos. If your priority is process control with network communication, this is where the extra money goes.
Final choice by use case
For a bench or portable thermocouple temperature and low-voltage logging job with USB simplicity, choose the Pico Technology TC-08.
For an industrial process recorder/controller with a color display, Ethernet, universal analog inputs, and relay outputs, choose the Eurotherm Nanodac.
