thermometers. In thermometer. Gas thermometer s work best at very low temperatures. Liquid thermometers are the most common type in use. They are simple, inexpensive, long lasting, and able to measure a wide temperature span. The liquid is almost always mercury, sealed in a glass tube with nitrogen gas making.thermometer Students Britannica Kids Homework HelpTemperature is measured by an instrument called a thermometer. Most common for measuring air temperature is the liquid in glass thermometer, which consists of a glass tube enlarged at the bottom into a bulb that is partially filled with mercury. The tubes bore is extremely smallless than 0.02 inch (0.5 millimeter) in diameter.Bolometer measurement instrument BritannicaBolometer, instrument for measuring radiation by means of the rise in temperature of a blackened metal strip in one of the arms of a resistance bridge. In the first bolometer, invented by the American scientist Samuel P. Langley in 1880, a Wheatstone bridge was used along with a galvanometer that produced a deflection proportional to the intensity of radiation for small deflections.
Measurement of this temperature rise and a knowledge of the weight and heat characteristics of the container and liquid permits the total amount of heat generated to be calculated. The design of a typical bomb calorimeter is shown in the Figure. The material to be analyzed is deposited inside a steel reaction vessel called a bomb.Infrared Thermometers Temperature & Infrared Thermometers 1 16 of over 1,000 results for Industrial & Scientific Test, Measure & Inspect Temperature & Humidity Thermometers Infrared Thermometers Hand held Digital Infrared Temperature for Baby Kids Adults Non Contact Smart Sensor Accurate Instant Reading Ear Forehead Thermometer LED Display Ear Temperature Measure with Fever Alarm (Purple)Infrared Thermometers Temperature & Forehead Thermometer Non Contact Infrared Thermometer for Baby Kids and Adults,Accurate Instant Readings Temperature,Measurement in 1 Second,Three Color Display Mode by WOLFBOX $41.94 $
