The main housing of the unit is brass, and the dial is
covered by a glass crystal. The temperature
display is in Fahrenheit and centigrade.
The thermometer makes use of a bimetallic mechanism which should be
accurate enough for its intended use.
The unit is assembled in Vermont, but the components are
made in China. It has a lifetime warranty.
The thermometer includes a brass mounting arm which can be
reversed to mount either from the right or left side. I am sure they think this is adequate, but
for our location, mounting from the side did not work out. For us, it was best to mount the unit
vertically. This meant that I had to
come up with a different holder. I sunk
a copper pipe into the ground near the intended window. I then used the mount arm as a template to
mark and drill holes into the end of a ¾ inch flat metal strip which was
inserted into the pipe. I mounted the
thermometer to that flat metal which holds the thermometer nicely. As an added benefit, if we want, we can
rotate the unit in this mount so it can be seen from different locations if
needed.
The tricky part of the installation relates to the need to
adjust the thermometer reading prior to use.
This requires disassembly of the thermometer to access the
mechanism. Be sure to keep the outer box
as it has the directions for adjusting the thermometer printed on the inside. My
Conant thermometer read 100 degrees when it should have read 68, so you will likely
have to adjust yours.
To adjust, you have to first remove the retaining ring which
holds the glass crystal against the main brass housing. This is easy enough, but I imagine could also
be a way to potentially break the glass crystal. Just be careful. Hold one hand over the crystal
and the ring will spring out away from it when you pry it away as instructed.
Carefully remove the dial from the housing. At this point, I placed the dial back over the
inverted glass crystal, just to have a place to set the unit while adjusting it
in order to keep the needle away from obstructions. It is best to do this in a place next to a
thermometer you trust as accurate. It is
also imperative that you allow adequate time after an adjustment for the thermometer
to acclimate to the true temperature again, as it is fairly sensitive and will
be impacted by you holding it during adjustments. It took several small adjustments and several
waiting periods to finally get to a point that my Conant thermometer was stable
and in agreement with the source temperature.
When you think you have it right, let it sit for a good long time to
make sure. It is easier to wait then it
will be to take it all apart to re-adjust when you realize you did not allow
enough time.
Reassembly is done in the reverse order of disassembly. You might check the dial prior to closing up as
it shows every finger print from any inadvertent touch you made in the
adjustments. Also, clean the inside of
the glass if needed. The tricky part
here is getting the retaining ring back in place. Just start at the bottom as directions suggest,
and slowly work it in around the dial.
It requires a significant amount of pressure and dexterity to do this,
but it can be done.
Now the unit should be ready to mount making use of the
provided mount and screws, or your own method if needed.
