Exactly. We need a continuously record the temperature. Therefore, the two 
proposed options, the pencil and the thermocouple are not suitable for our 
purpose. We will use several thermocouples within the cone, temperature 
recording. But abroad, will be in direct contact with the flame. That is why, 
we want to use an infrared thermometer. Does anyone know how we can do one and 
connect it to the computer?

    Thermocouples are cheap and work well,
      but if they are embedded in a sample that gets torched, they will
      at best record the surface temperature of the sample at the brief
      moment they are at the surface. It may work - and even provide
      usefull data - but an IR thermometer will read the surface
      temperature continuously.

          Here is another ebay seller with all thermocouple options,

            A type K thermocouple is good to 1250 C.  It will need a
            simple instrumentation amplifier to get the signal voltage
            to a range compatible with the Arduino A/D converter.  For
            about $10 in parts you can build your own IN-AMP.  There are
            several choices for single chip IN-AMPs that will do the job
            and here is a board from China for $10, and the chip output
            is 10mv/deg C.

                              It
                                is a good idea. The main problem I see
                                is that we need to measure high
                                temperatures. I do not know exactly how
                                much, but around 1200ÂșC. And this only
                                measures halfway. Do you know if there
                                is a sensor for arduino with this
                                possibility?

                                    It is quite easy to build a data
                                    logger with an Arduino based micro
                                    controller, SD card, SD card socket,
                                    HEF 4050 voltage level shifter,
                                    DS1307 RTC and one (or more)
                                    MLX90614 IR thermometer(s) which
                                    communicate(s) over the I2C bus as
                                    well.
                                    I am just doing this for a medical
                                    project.

                                          we continue the investigation
                                          of ablative materials.
