Problems solved by technology

Usually the measurement needs to continue for a certain period of time, such as three minutes, to obtain accurate results. If the measurement time is too short, the result will be inaccurate. If the measurement time is too long, the risk of thermometer rupture will be increased due to the lack of cooperation of the measured object. The oral mercury thermometer in the

Abstract

The disclosed mercury thermometer comprises a sealed glass tube with back end set an electronic timer that composes by a timer circuit, a LCD linked to former circuit by a cable, a startup button, an adjusting button, a cell and a buzzer. Wherein, it can set multiple time intervals by the adjusting button, and turns on the LED for brightness. This invention can improve measurement precision efficiently.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to a temperature measuring device, in particular to a medical oral mercury thermometer, in particular to a mercury thermometer capable of setting the measurement time. Background technique: [0002] In the prior art, oral mercury thermometers are commonly used to measure body temperature. The oral mercury thermometer is composed of a sealed glass tube, and a mercury column is arranged in the glass tube, and the volume expansion of the mercury when heated is used to reflect the body temperature. Usually the measurement needs to continue for a certain period of time, such as three minutes, to obtain accurate results. If the measurement time is too short, the result will be inaccurate. If the measurement time is too long, the risk of thermometer rupture will be increased due to the lack of cooperation of the measured object. The oral mercury thermometer in the watch does not have a time prompt...
