I have Datanab temp sensors scattered throughout my house, and I'd like to calibrate them so I can make smart decisions about where to direct the heat.
I had a cheapo thermometer I bought (probably at Walmart) that has a display, and a little sensor at the end of a wire. So, though I didn't think the cheapo thermometer was correct, I figured I could at least calibrate all the datanab sensors to this cheapo thermom and then they may still be wrong, but at least they'd be wrong to the same standard.
However, I found my simple mercury thermometer and it was giving entirely different readings. Granted, it's a pretty coarse scale to read from...no digital readout there...but might correct things back to within a degree.
Is the mercury thermometer probably the most accurate of all the "sensors" here? Maybe I could calibrate the cheapo therm to the mercury, and then use the cheapo to calibrate the datanab sensors?
Or is there an easier, cheaper, or more reliable way? (preferably all 3)
