MARATHON BA030001 Vertical Outdoor Thermometer - 16-Inch

As someone who's grown tired of the wild inaccuracy of dial and digital thermometers, even after calibrating them more than once, it was nice to find a simple, old-school glass thermometer that came out of the box with dead-on accuracy (checked with a lab-grade laser thermometer) and can be expected to remain accurate/linear across the reasonable temperature range here (about 0-100). It mounted easily on a porch pillar that is perfect for temperature averaging and visible through a sliding glass door. Yes, it has a narrow viewing angle; that's inherent in this style. But I'll take a moment extra to read a temperature I can trust; not much use in being able to see a +/-20 degree temp at a glance. (By the way, you can recalibrate this model of thermometer if needed: carefully remove the glue bead and slide the tube up or down on the holder until it's aligned. Check the adjustment a few times across temp changes, then use a drop of silicone caulk or adhesive to lock the tube in place again.)

Easy to install. Gage larger enough to see. I put mine in the shade for accurate measurement. Great price for what I got :)ACCURATE!

It is a very nice and practical outdoor thermometer. Wish the numbers were larger and easier to read from a distance.

easy to read

Order this large thermometer so I could see it from a distance. The hard part is that you have to be directly in front of it to see the red line that shows the temp. Not even almost in front of it. Not recommended.

Very easy to read. Happy with product in greenhouse

Easy to see and having two mounting holes allowed me to fasten it so the wind can not move it or blow it down.

The product seems to be okay but it requires someone to be at home and a signature which is ridiculous for a thermometer. It does not contain mercury so that could not be the reason . Will not reorder from this company because of that reason.
