USB TC-08 Thermocouple Data Logger

The TC-08 Thermocouple Data Logger offers industry–leading performance and is an inexpensive answer to your temperature measuring needs.




Features:
8 channel thermocouple data logger 
Measure from 1 to 160 thermocouples 
Measures from -270 to +1820 °C 
Automatic cold junction compensation 
High resolution and accuracy 
Fast sampling rate — up to 10 measurements per second 
USB interface 

Wide temperature range
The TC-08 thermocouple data logger is designed to measure a wide range of temperatures using any thermocouple that has a miniature size thermocouple connector. Additionally, the TC-08 can also measure other sensors using a 70 mV range.

Featuring built-in cold junction compensation (CJC), the TC-08 has an effective temperature range of -270 to +1820 °C (the actual temperature range depends on the thermocouple being used).
All the benefits of USB

The TC-08 connects to the USB port of a Windows based PC and enables the host PC to automatically detect the TC-08 — avoiding the need for any complex setup procedures. The USB connection also allows the TC-08 to be powered directly by the USB bus — eliminating the need for an external power supply and making the TC-08 ideal for measuring temperatures both in the lab and in the field.


Measure up to 160 thermocouples simultaneously
The TC-08’s USB connectivity allows up to 20 TC-08 USB data loggers to be used simultaneously on one PC — making the TC-08 ideal for use as a large multi–channel temperature acquisition system with a cost per channel significantly lower than other systems of this size.

Fast and accurate temperature data acquisition
With the TC-08 thermocouple data logger your measurements can be made both fast and accurately.

The low conversion time of the TC-08 means up to 10 temperature measurements can be taken every second. Whilst the high (20–bit) resolution ensures that the TC-08 can detect minute changes in temperature.
All you need in one easy–to–use unit

Temperature data acquisition with the TC-08 is very easy — simply plug the TC-08 into a USB port on your computer, connect your thermocouples, and you are ready to measure temperatures.

The easy-to-use PicoLog data acquisition software is supplied with the TC-08 — allowing you to start measuring and recording temperatures with the minimum amount of effort. The intuitive user interface of PicoLog makes it easy for you to set how frequently you want to take a measurement, and the number of measurements you want to take.
