Thermometer

Introduction

Thermometer is the science and practice of temperature measurement. Any measurable change in a thermometric probe can be used to mark temperature levels. It should later be calibrated against an internationally agreed unit if the measure is to be related to other thermodynamic variables.

An instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol .A thermometer can be any system with a measurable property which depends strongly on temperature. The working thermometers are useful in most laboratories as opposed to standard thermometers, used in calibration laboratories. [tabletshablet.com]

Applications:-

Temperature is one of the most measured physical parameters in science and technology typically for process thermal monitoring and control. But the thermometer is not only applied to measuring temperatures for thermal control. But as an indirect measure of many material properties like thermal capacities and enthalpy changes, relative humidity ,thermo - optical properties and other radiation characteristics etc.

Temperature regulation in thermostats can be based on efficient thermal buffering or on controlled heat transfer from a source or to a sink. A thermometer is a device that maintains a system at a constant temperature, issuing a control signal when out of limits.[tabletshablet.com]

A common thermostat consists of a bimetallic strip that bends as it expands when overheating, switching of the electrical power supply.

 How do you operate Thermometer?

Clean the tip with cold water and soap then rinse it.

Turn the thermometer on.

Put the tip under your tongue, towards the back of your mouth.

Close your lips around the thermometer.

Wait until it beeps.

Check the temperature, discard the cover, and record temperature and time.

Digital Thermometer

These digital thermometer are much safer as they contain mercury, they are decidedly more accurate and precise than traditional device. The digital thermometer results and readings are displayed much faster on this device as well. These digital instruments are much easier to use. The digital thermometer comes with a beeper or an alarm to let you know when the temperature has been taken. [tabletshablet.com]

A body temperature thermometer is a device that every home medical kit should include .Digital thermometer offers impressive features. That gives great accuracy, easy to read results.  And contain harmful chemicals. With several options available today, we have simplified your choice.

 Besides the fact that digital thermometers provide faster readings it is slowly replacing conventional mercury thermometers because this includes various technologies that provide better accuracy. This has even made them a popular choice for various professional industries.

Accusure digital thermometer can read temperature fast and with high accuracy. This is handy and easy to use. You can even carry the thermometer in your bag. The display is easy to read and a digital thermometer is not expensive. A thermometer is a device that enables you to measure your temperature gradient digital thermometers accomplishes this task by using electronic heat sensors. 

A digital thermometer one over a mercury thermometer has a few benefits.

Benefit of Digital Thermometer

Digital thermometer can read temperature fast and with high accuracy.

It is handy and easy to use.

You can carry the thermometer in your bag.

The display is easy to read.

A Digital thermometer is accurate and quick to use.

A digital thermometer is not expensive 

This is not requiring any special maintenance.

It is easy to use a digital thermometer compared to the ordinary clinical thermometer.

The heat sensor of the digital thermometer is at the lip of the thermometer.

Based on the tested record of the experiments, the accuracy of a digital thermometer.

The accuracy is better than the normal mercury thermometer.

It is convenient to use a digital thermometer.

Non Contact Infrared Thermometer 

Non contact infrarethermometers can be used to measure temperature rapidly and non –invasively ,potentially causing less distress to children than conventional methods ,like infrared tympanic thermometers Non –contact infrared thermometers can provide temperature readings within seconds.

NCIT allow a person’s temperature to be taken with minimal or no (NCIT). Contact with the person.NCIT are held three to fifteen cm away from the patient and typically measure temperature on the forehead or temple.[tabletshablet.com]

Benefits of Non Contact Infrared Thermometer 

Non contact approach may reduce the risk of spreading disease between people being evaluated 

Easy to use

Easy to clean and disinfect 

Measure temperature and displays a reading rapidly 

Provides ability to retake a temperature quickly.

Infrared Thermometer 

 Infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black body radiation emitted by the object being measured. This permits temperature measurement from a distance without contact with the object to be measured. Temperature is surely the most frequency measured physical quantity .There is various options available for measuring temperature using infrared light. In addition to traditional thermometers, pyrometers are also proven instruments for measuring temperature.

Infrared thermometer is ideal for taking temperature measurement at a distance. They provide relatively accurate temperature without ever having to touch the object you are measuring. [tabletshablet.com]

Benefits of Infrared Thermometers

It is fastest ,accurate temperature readings 

It is easy to read

It hygienic

It convenient 

Stress free for both the patient and caregiver 

No ongoing costs 

Multiple uses
