Review on General Purpose Thermometer Immersion B60700 1600 by Timothy Weems

I bought this thermometer to measure air temperature including outside temperature measurement for meteorological observations. The thermometer responds quickly to changes in air temperature. I took it outside tonight and the temp adjusted from 75F to 25F fairly quickly (less than 5 minutes). The glass bulb at the base of the thermometer appears slightly curved compared to the rest of the glass tube, but the thermometer works well. I assume this is a normal result of the glassblower manufacturing process.
