Product Specs

The TC-08 thermocouple data acquisition module is designed to measure a wide range of temperatures using any thermocouple that terminates in 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 measuring range of -270 to 1820°C (the actual temperature range depends on the thermocouple type being used).

The TC-08 can be used with thermocouple types J, K, T, E, R, S, B and N and outputs can be viewed in degrees F, C or mV. The unit is accurate to 0.2 percent ± 0.5 degrees C and has a resolution of better than 0.1 degrees C for most thermocouple types.

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.

The TC-08’s USB connectivity allows up to 20 TC-08 USB data acquisition modules 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. The low conversion time of the TC-08 means up to 10 temperature measurements can be taken every second, while the high (20 bit) resolution ensures that the TC-08 can detect minute changes in temperature. With the TC-08 thermocouple data acquisition module your measurements can be made both fast and accurately. Simply plug the TC-08 into a USB port on your computer, connect your thermocouples, and you are ready to measure temperatures.

With the included TC-08 Recorder software, you can configure multiple (USB) TC-08s, set the sampling interval from 0.1 seconds to several hours and set the maximum number of readings. You can also tell TC-08 Recorder what to do once the thermocouple readings have been taken - either: Stop; Repeat Immediately (start again); Scroll (oldest recordings disappear); or Repeat After Delay (where the delay is set by the user). Mathematical operations can also be performed on the thermocouple outputs: for example to output one temperature relative to another.

Rated 3 out of 5 by from Works well with some flaws We use these for performing uniformity surveys of heat treat furnaces. We need 5 thermocouples in each furnace and we do several furnaces at the same time. We plug several of these TC098's into a USB hub to read them all at the same time. When we connect thermocouples that are inserted into different furnaces into the same TC-08 and the temperature gets above about 1,400-F, they do not work. The temperature readings are extremely erratic and bounce around about 300 degrees up and down. Omega tech support was unable to find a solution. But they work well when all thermocouples that are plugged into the TC-08 are in the same furnace.

I need 9 simultaneous thermocouple measurements for the TUSs I perform. If I buy 2 TC-08,s and connect them both to the same computer, will the software be able to recognize, track, and save the temperature data from the thermocouples on both devices?

Asked by: michael schutt
Hi there, yes, you can use multiple TC-08's with one software instance, the instructions are in the manual at this link: https://assets.omega.com/manuals/M4526.pdf. Thank you!

Do you provide some kind of API for software integration?

Asked by: Pablo D
We do not supply an API but we do provide examples with other higher level languages such as C++, VB and others. Please download manual for details.

Does the logger output in standard RS232 format? When the USB plugs in, does it register as a com port, or something proprietary? I have RS232 datalogging software that I'd like to use, rather than the Omega software. The RDXL-SD-Series does this.

Here is a link to the Programming Examples Docuymentation for the TC-08 this is the only support we offer for custom programming for this unit: ftp://ftp.omega.com/public/DASGroup/products/TC-08/ProgrammingExamples.zip

Has the location for the TC-08 software changed? I can't find it on the previously specified web address.
