    AK900 Thermisters

    Are the AK900 thermisters compatible with the Testo 550? Not the connections, but do the thermisters share the same temp/ resistance curve. I have a couplr for the Testo that was stolen, thought I might change connectore and re-use them.

    They are different.

    Digi-Cool uses standard 10k @25ΊC NTC thermistors.
    Testo's NTC thermistors have a different resistance curve, no idea if they have the same specs as any commonly available thermistors.
    If more government is the answer, then it's a really stupid question.
