We ordered two but either the storage condition is bad or the transportation situation is bad, the minimum, the end of the mercury indicating the maximum temperature has been choppy and it was impossible to measure the actual temperature. It seems impossible to use it thought that it will be fixed if it is used for a long time.
Temperature control of the greenhouse installed in the room

I used the same thing from before. Since passion fruit which is growing now is weak cold weather, it is used for the temperature control of the greenhouse which is exclusively placed in the room. Although it is an old-fashioned thermometer (mercury column type), it is more accurate than the digital type thermometer and durability is semi-permanent.
Although I grow vegetation weak at low temperature, I was concerned about how much temperature was falling down in the morning and evening in my own greenhouse and I remembered the thermometer that could measure the lowest temperature in my school days as well. I am relieved that temperature control which I was concerned about can be done because both maximum and minimum temperatures are known.
