- What are the parts of a thermometer

Thermometer is a instruments which measures human body temperature i.e degree of heat. The basic parts of thermometer which help measuring body temperature are the nib or tip filled with mercury and scale. It actually perform two functions first one is sensing and the second is scaling.

Sensing: It is the function which detect temperature through tip (in case of contact thermometer) and probe (in case of infrared thermometer)
Scaling: It is second function through which temperature is indicated either by mercury in glass tube with scale or through digital display




- Can i use a general purpose infrared thermometer to measure human forehead temperature

If the question is can you use infrared thermometer on humans well the answer is yes. The temperature of human is also measured through its forehead. It can be easily obtained with the help wall thermometer or infrared digital thermometer.

Forehead thermometers normally come as non-contact digital thermometers. These thermometers use digital infrared technology or IR technology. The probe of these thermometers is equipped with sensor which measure human body temperature through infrared wave.

How to use an infrared thermometer is simple. When directed towards forehead, the body temperature of human is recorded through temporal artery temperature. Because fever temporal temperature provide accurate reading. 

-Why does my Exergen thermometer screen show the LO signal all the time?

When you read the instruction for use of Exergen Thermometer and follow steps of how to use Exergen temporal thermometer. There are different messages which appear on the display
 
These are SCN, HI, LO and ERR. The “LO” message on the display stands for low temperature. Which means the target temperature measured is lower than 60°F/15.5°C. The operating environment temperature range of the thermometer is 60-104°F/ 15.5-40°C. The main reason for this “LO” message all the time is that it is actually measuring the room temperature which is less than 60°F/15.5°C.

- How does infrared thermometer work?

Infrared thermometers are also known as non-contact digital thermometers. These thermometers use digital infrared technology or IR technology. The probe of these thermometers is equipped with sensor which measure temperature through infrared wave.
The probe consist of lens to focus infrared energy. It basically detects energy emitted by the surface as result of infrared waves from thermometer and converts into heat. The intensity of heat is displaced in units such as Celsius or Fahrenheit. It is expected for thermometers to read temperatures correctly.

- Why is digital thermometer more advanced than clinical thermometer?

In today’s life, digital thermometers have taken over traditional mercury filled glass tube thermometers. There are many reasons behind it. 

i. Breaking of mercury glass tube causes safety concerns.
ii. Obtaining reading of temperature
iii. Disinfecting of instrument

The digital thermometers have addressed all such concerns over traditional thermometers such as;

i. No mercury is used resulting no leakage or breakage
ii. Easy to read temperature though LCD display
iii. No need to disinfect as the temperature reading is obtained without physically contacting with the body (Non contact thermometers)


- What is the most accurate thermometer for adults?

The accuracy of any Thermometer depends upon its manufacturer. The company provides product guide with the product. It provides instructions for usage. 

In forehead Thermometer, the distance between Thermometer and forehead of person must be maintained as advised to get more accurate readings. Further, every instrument has its error variation which is also mentioned in product guide.

Temporal  Temporal thermometer check temperature with the help of advance sensors and takes more readings to get accurate temperature compared other such as rectal or armpit.


- Can hormones cause a low body temperature?

Ovulation normally causes minute change in body temperature which can only be measured by Basal Body Thermometers. During ovulation, change in hormones causes change in temperature.

It normally remains high almost two weeks. In case of conceiving, the temperature continues to remain high. If the temperature decreases, it gives sign of upcoming periods. All this happen due to changes in hormones. Due to this people use basal thermometers to predict ovulation.

In normal life, the temperature of body changes as soon we wake up from sleep and start physical movement. So it is advised to take temperature right after awakening from sleep and before leaving bed to washroom to measure accurate temperature. 

Because in this state the body is in rest and it’s a perfect time to record it. Basal Body Temperature is also called lowest body temperature. Basal Body Thermometers are known as bbt thermometer. The price Basal Thermometers vary depending upon accuracy and manufacturer.
