Product review (5 stars): A serious tool for measuring temperature and humidity
This is a serious tool for measuring temperature and humidity.  It measures both quickly and accurately.  You can read temperature in F or C.  Its ergonomics make it practical for probing the temp. and humidity inside conduits, vents, and so forth.  This is a very nicely made instrument, comes with a leather slip-on case, and works great.
