How to calibrate a thermometer with ice

Calibration is a temperature comparison between a platinum resistance instrument and one or several thermometers, in this way we obtain a deviation and a detailed certificate of the calibration of thermometers or for any device for any interval.

The calibration of a thermometer or any temperature instrument is one of the specialties of our laboratory, we are an accredited laboratory before the EMA, Mexican Accreditation Entity to offer temperature measurement services, at the end of this activity or any of our services you will receive a valid calibration certificate to face any quality audit, for us it is very important to offer the best thermometer calibration service, we know that your processes and products are very important and temperature measurement makes a big difference to improve and find areas of opportunity for your company, service or product.

It is true that nowadays instruments that measure temperature or other metrological variables are becoming more and more sophisticated, some have the auto function “cal” or calibration, referring to an auto adjustment, this should never be confused with a calibration service in which a rigorous process of temperature measurement is performed in order to know the uncertainty of measurement of your instrument(s).

How to calibrate a thermometer

We, more than anyone, know how important it is for you or your company to have state of the art temperature measuring instruments that provide great value to your production processes, that is why our engineers are constantly training and updating in order that your company or business can be totally sure that in sidelab, temperature calibration laboratory you can find a reliable strategic partner for the calibration of your thermometers, Thanks to various strategic alliances with which sidelab counts and first hand information you can be sure that your instruments will be calibrated with great professionalism and extensive experience in this sector, often fills us with great happiness that the most important industries and companies of great trajectory in Mexico consider us as a strategic partner in the measurement of temperature instruments.

How to calibrate an infrared thermometer

Infrared radiation is a low-frequency electromagnetic radiation which, unlike visible radiation, is outside the wavelength that our eyes can detect. The radiation emitted depends on the emissivity. At the same temperature two bodies with different emissivity will generate different radiation and therefore an infrared thermometer will measure differently. Since most gases do not emit in the 8-15µm band, which is the band of thermometers, they do not measure air temperature and therefore are not affected by it. Infrared thermometers measure the surface temperature in a measurement area, not the internal temperature of bodies. The farther away they are from the measuring surface the larger the measuring area, so the farther away from the object the greater the possibility of measuring unwanted surfaces.

The picture shows a 4:1 infrared thermometer, which means that at a distance of 4 cm the measuring area will be 1 cm. With an 8:1 device at a distance of 8 cm the measurement area will be 1 cm. Therefore, when using infrared thermometers, the measuring surface and the distance to the surface must be taken into account, since the greater the distance, the greater the probability of measuring an area other than the desired area Advantages Disadvantages

How to calibrate an alcohol thermometer

A thermometer is a device which measures temperature or a temperature gradient. In general they have two important elements: a temperature sensor (for example, it can be the bulb of a mercury-in-glass thermometer or the digital sensor in an infrared thermometer), in which some variation occurs with a change in temperature; and some means of converting this change into a numerical value (for example, the visible scale that is marked on a mercury-in-glass thermometer or the digital readout in an infrared model).

Several authors have credited the invention of the thermometer to Hero of Alexandria, however the thermometer was not a single invention, but a development. Hero of Alexandria (10-70 AD) knew the principle that certain substances, especially air, expand and contract and described a demonstration in which a closed tube partially filled with air had its end in a container of water. The expansion and contraction of the air caused the position of the water/air interface to move along the tube. Such a mechanism was later used to show the heat and coldness of air with a tube in which the water level is controlled by the expansion and contraction of the gas. These devices were developed by several European scientists in the 16th and 17th centuries, especially by Galileo Galilei.
