length & 12 in. L x 1 in. W size. The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam (). It consists of a bulb containing mercury attached to a glass tube of narrow diameter; the volume of mercury in the tube is much less than the volume in the bulb.

The volume of mercury changes slightly with temperature; the small change in volume drives. Buy AS Thermometers - Meteorological - Maximum, minimum and ordinary from SAI Global.

Six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours.

It is used to record the extremes of temperature at a location, for instance in meteorology and was invented by a British scientist James Six, born in Canterbury, in ; the same basic design remains in.

The mercury thermometer is a device commonly found within amateur weather stations. It consists of a glass bulb connected to a stem, in which liquid mercury is placed. As the temperature increases, thermal expansion causes the mercury volume to increase and extend along the glass tube.

A scale is written on the glass tube, allowing the observer. Thermometers - Meteorological - Maximum, minimum and ordinary. Specifies requirements for the glasses, filling, mounts, sheaths and figuring of maximum, minimum and ordinary thermometers as well as fully manufactured thermometers.

The Belfort Maximum-Minimum Thermometer is used to indicate the temperature extremes reached over a given period.

Maximum and minimum thermometers on stainless steel mounting plates are clamped to the Townsend Support which holds them in the proper position and allows for resetting the maximum thermometer.

The maximum thermometer has a mercury filled bulb. Group for Federal Meteorological Handbook No. 1 (paragraphs, and ). • Changed address and phone numbers for OFCM (paragraph ).

The alcohol-in-glass minimum thermometer contains a dumbbell-shaped index that is kept on the bulb side of the meniscus by surface thermometer is installed in a horizontal mounting (see Townsend support) so that as the temperature falls, the index is pulled toward the bulb and remains at the minimum point as the temperature rises.

A bimetallic thermometer. Note 1: It has been found by experience that ASTM Thermometers, although developed in general for specific tests, may also be found suitable for other applications, thus precluding the need for new thermometer specifications differing in only minor features.

However, it is suggested that technical committees contact E before choosing a currently designated. Max/Min Registering Thermometers show maximum and minimum temperatures in °F and °C since last reset, as well as current temperature. The reset button makes it easy to start a new temperature measurement.

MA is a traditional Spirit-filled thermometer that displays temperatures ranging from °—°F (—50°C). It has 1° : $ Maximum, minimum and ordinary (i.e. wet and dry bulb) glass-sheathed thermometers suitable for mounting in a louvred screen.

As the alcohol expands in response to temperature changes, the metal index on both sides of the thermometer record the maximum and minimum temperatures.

The lowest point of each metal index indicates the temperature. The World Meteorological Organization approves the use of all major types of thermometers, such as glass thermometers, mechanical thermographs, and electrical thermometers (resistance and semiconductor types). Three types of measurements are performed: temperature, maximum temperature, and minimum temperature – all in specified time intervals.

Temperature scales differ in two ways: the point chosen as zero degrees, and the magnitudes of incremental units or degrees on the scale. The Celsius scale (°C) is used for common temperature measurements in most of the world.

It is an empirical scale that was developed by a historical progress, which led to its zero point 0 °C being defined by the freezing point of water, Other units: °C, °F, °R.
