The Maximum Thermometer is designed for precise routine observations of air temperature, specifically to measure the highest temperature reached over a given period. Employing the principle of differential expansion of a pure liquid within a glass container, this liquid-in-glass thermometer features a main bulb fully filled with liquid and a fine bore stem partially filled, ensuring accurate temperature readings. The temperature is indicated by the length of the liquid column in the stem, which expands or contracts relative to the glass tube as temperature changes. This thermometer is carefully calibrated against standard thermometers, with a temperature scale clearly marked on the stem or on an attached scale for easy interpretation of maximum temperature readings. Ideal for meteorological, environmental monitoring, and industrial settings requiring reliable maximum temperature data.

The thermometer uses the expansion of the liquid inside the bulb and stem; the liquid length extends to the maximum temperature reached and stays at that level until reset or cooled down.
Yes, it is designed for routine ambient air temperature monitoring and can be used outdoors with appropriate protective housing.
Yes, the thermometer is available calibrated with temperature scales marked in either Celsius or Fahrenheit based on user requirements.
A pure liquid with reliable thermal expansion properties is used, commonly mercury or colored alcohol depending on model and safety standards.
The thermometer provides an accuracy of ±0.5°C, ensuring precise maximum temperature readings for professional use.

For routine observations of air temperature, including maximum, minimum and wet-bulb liquid-in-glass thermometers are commonly used. Such thermometers make use of the differential expansion of a pure liquid with respect to its glass container to indicate the temperature. The stem is a tube having a fine bore attached to the main bulb: The volume of liquid in the thermometer is such that the bulb is filled completely but the stem is only partially filled at all temperatures to be measured. The changes in volume of the liquid with respect to its container are indicated by changes in the length of liquid in the stem; by calibration with respect to a standard thermometer, a scale of temperature can be marked on the stem, or on a separate scale tightly attached to the stem.
