Rated 1 out of 5 by from Terrible software, need an actual mini CD drive Bought this for our lab, functionally it's fine but in order to set it up and/or pull the data from it, you need an obsolete CD drive. Pretty ridiculous that the USB driver software isn't either included or availibe on their website. You have to legitimately find a CD drive that can take a mini (4cm) CD.

Specs on the logger I am looking at, says Thermocouple Connection: Female sub-miniature thermocouple connector............ what Gage Wire is required to correctly connect to this "sub-miniature" connector?

Asked by: Ironman
Hello, thank you for your question. Our miniature connectors accept Stranded or Solid Wire up to Size 20 AWG. Other manufactures may have different specs.
