Maxima Minimum Maximum Green House Greenhouse Thermometer Hygrometer Mercury Analogue Mercury U Float

The Six's thermometer, or Maxima-Minima thermometer, records the highest and lowest temperatures over a period of time, typically using alcohol and mercury with steel indexes. Commonly used in meteorology, agriculture, and horticulture to monitor temperature fluctuations, especially in environments like greenhouses, this thermometer features minimum and maximum pins and a push-button reset. Suitable for indoor or outdoor use, it displays the current temperature and registers extremes since the last reset within a range of -40°C to +50°C. The U-shaped thermometer is mounted on a plastic casing and uses metal floats to indicate maximum and minimum temperatures.
