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.

Using the TC-08 Recorder
software, data can be viewed in a
spreadsheet and/or in a graph as
it is being recorded. Data collected
from previous recordings can also
be viewed in the TC-08 Player.
