Product review (5 stars): Great high quality indoor temperature/humidity gauge
I give this unit 5 stars based on the high quality of metal construction and on the accuracy of the readings.  You can pay a lot less for a plastic gauge that gives you indoor temperature and humidity but you will not get accurate readings, especially for humidity. I have a high-end weather set up for comparison and it agrees perfectly with the readings I get from the Fischer Instruments 146-01.  Should the humidity readings fail to track over time, the accuracy can be adjusted - which is also rare.

The unit is billed as a "Comfort Meter" and it has a grey zone in the middle of the display.  The comfort zone is when the point where both the temperature and humidity needles cross is inside the grey zone.  Unfortunately, the temperature range for "comfort" on the Fischer 146-01 is from 58F to 70F.  For myself and most others I know, most of this range wouldn't be considered comfortable for either winter or summer!

This meter would be great for use in a built-in humidor or wine cellar or even in a room with a lot of wood furniture or art work due to its accuracy.  For those applications the needle still might not be in the comfort zone under ideal conditions, but you can count on the device's accuracy and good looks to be a valuable addition to your home or office. Just ignore this device's comfort zone markings and you won't be disappointed.
