Thermometer

A thermometer is a device intended to measure the temperature of the body or some things.

Mercury thermometer(clinical thermometer) is the thin, sealed from both sides air-free capillary tube.

The reservoir, filled with mercury, is located on the lower part of this tube. The scale coming from reservoir has the graduation line from 34 to 42 Celsius degree. Each degree is divided into 10 small devisions indicating 0.1 Celsius degree

Before using a thermometer you should carefully read the instruction provided. If, after taking someone's temperature, the thermometer indicates a raised temperature, you should take another reading about 20 minutes later to confirm it. A normal temperature usually ranges from 36-36.8C (97.7-99.1ºF). A temperature of 38C (100.4F), or above, is classified as fever.

If you're checking the temperature in children, always stay with them during the reading, and put the thermometer away immediately afterwards.

Only adults should should use mercury thermometers because children are more likely to brake the glass or bite. Before taking a temperature you should shake the thermometer to make mercury go back into the bulb of the thermometer. Then thermometer is placed under armpit for some minutes. After that you may indicate the temperature on the graduation line.

Thermometer TB-3-M1 is intended to measure the temperature of the water with the range of 0 till +50 Celsius degree.

Along with medicinal thermometers, digital thermometers may also be used to take person's temperature.

When you are reading the temperature from the armpit, you should know that the temperature will be about 0.5C lower than the body has. That's why you should add nearly 0.5C to the reading to get a more accurate idea of the temperature.

Armpit readings are not the most reliable or accurate way of taking the temperature. However, they may be a more suitable and safe way of taking the temperature in children.

When are you taking an armpit readings, put the digital thermometer directly under the armpit, and hold the arm gently against the chest. You may have to leave the thermometer there for nearly five minutes to get an accurate reading.

Temperature readings from the mouth are not suitable for very small children because they may bite the thermometer. However, they are suitable for adults adults. Place the thermometer under the tongue for nearly two-three minutes. If the patients has just eaten something very hot ot cold, wait about 10-12 minutes before taking a reading.
