I found this strange thermometer. It has two thermometers in a glass tube.one I can see that it is a very accurate centigrade thermometer that can read degrees to 2 decimal points. -20 to +50degree c the other one has the bulb immersed in a mercury filled chamber. . It can only be read when the large mercury filled bulb is held vertically. You have to use a jewelers scope to read it. Manufactured by KAHLSECO, EL CAHON CA
