Subject: [RE-wrenches] Affordable, Quality Thermometer

I have been looking into the possibility that a relatively new weather
station in the Los Angeles area -- a RAWS station to be precise -- is
consistently recording temperatures about 5 deg F higher than actual. I have
been basing my opinion using a standard Hg/glass thermometer and a IR gun.
Both of my units usually agree to within 1 degree (rarely 2 degrees).

What I would like to know is if there is an affordable "gold standard"
thermometer out there for purchase. Presumably its calibration would have to
be traceable to a NIST standard of some sort. I am looking for less than +/-
1 deg F resolution and accuracy. The temperature range I am primarily
interested in is 70 deg F to 115 deg F, and 15 deg to 70 deg F would be
icing on the cake. 

I would settle for something that I could read and record the data by hand.
If there was a version that had a interface to a laptop or smart phone would
be great
