Hi and thank you for your post.
You cannot achieve the 10Hz sample rate, however you can achieve the 1Hz sample rate. We have the USB-TC08, this is an 8 channel thermocouple logger, you can have multiple loggers connected to one PC logging using one instance of the software.
***Hi just to add you will not get 1Hz sampling updates with multiple devices. You can if you have one TC-08, however with multiple devices there are other associated overheads, it is difficult to give an exact figure***
Hope this helps.
