Found a Vaisala HMI 36 Temp Humidity meter that does not have a probe.  Anyone either know where I can find a PDF manual, or know a probe model that is compatible with it?  It doesn't use the round connector like some models.  It has what looks like a DB9 connector on the rear.
"I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind."
