At PCE Instruments you will find both contact and non-contact temperature meters as well as devices for measuring and recording temperature. There are temperature meters to measure different temperature ranges between -200 and 1767ºC. Measurement of temperature is done in many different sectors. We also offer temperature meters that can indicate temperature in ºC, K (Kelvin) and ºF, such as the PCE-880 temperature meter, as well as others that are water resistant. A wide range of thermal elements and type-K sensors are available for temperature meters. ISO calibration certificates, which include a laboratory calibration, can be ordered for most of our temperature meters. At the end of this page you will find information about non-contact temperature meters or you can visit the link: infrared. Please read: how to use an infrared thermometer. If you find yourself in the situation that you can't measure the surface temperature of a particular material, have a look at our contact thermometer. Moreover you can find other combined temperature meters as climate meters or thermo hygrometers. We offer a big variety of temperature meters which affect your daily life concerning industry, trade and hobby. Partly the ascertained data can be stored or directly transferred to your computer.
If you can't find the temperature meters you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: UK customers +44(0) 23 809 870 30 / US customers (561) 320-9162 and our technical staff will advise you regarding our products. Our engineers and technicians will be happy to help you with the temperature meters, and of course, with the other products in the field of regulation and control, and scales and balances.

Non-contact temperature meters.
Our infrared temperature meters measure temperature by way of the infrared radiation of an object. All non-contact temperature meters contain a targeting light to ensure the correct surface area is being measured. Infrared temperature meters can only measure the temperature of exposed surfaces and not through glass. Some models possess a preset K value, and others allow the user to choose the K value depending on the material being measured, whether it's paper, wood, metalic surfaces, etc. If the user measures shiny metalic surfaces, such as cylinders, the device can only be used to determine tendencies in temperature as it's not possible to measure absolute temperature, with a non-contact temperature meter on polished or shiny surfaces. Please read: how to use a non-contact temperature meter.

Video of use with temperature meters
In this video we can see the PCE-T390 series temperature meters performing a measurement by means of 3 of its 4 channels the temperature of three different points of an engine. We use two alligator temperature probes TF-109 as well as a thermal sensor TF-500.
Thermometers are instruments we use to measure the temperature of people or things. The most used and known temperature meters are mercury temperature meters used to measure peoples temperature and consisting of a graduated glass capillary and a pool of mercury in one end, but there are many types of temperature meters such as digital temperature meters that we have introduced which take temperature measurements on contact with an object these are suitable for any sector of industry. We even have infrared or laser temperature meters to take measurements at distance, without contact.
Temperature is a quality that refers to the cold or hot common concept. When an object is hotter it is because it has a higher temperature. The temperature increase is due to the degree of agitation of the materials particles, so the greater agitation, the higher temperature. So we can say that the temperature depends on the movement of the molecules that a substance is composed of. If these have more or less movement, there will be a higher or lower temperature, respectively. temperature meters are devices for measuring temperature and these have changed since their invention considerably. At first temperature meters were based on the principle of expansion. For this type of temperature meter you need a material with a high coefficient of expansion, so that as the temperature increases, the expansion of the material is easily visible. The material used for this type of temperature meter is mercury, enclosed in a glass tube that has incorporated within it a graduated scale. Today these kind of temperature meters have been banned due to the polluting effect of mercury which is quite high.
These models of temperature meters can display the measurement of Celsius, Fahrenheit or Kelvin. In the international system of units, the SI temperature unit is Kelvin which can be compared directly to Celsius where 0o Kelvin = -273.15oC and
0oC = 273.15o Kelvin.
First we can distinguish, so to speak, two categories in the measurement units for temperature: absolute and relative.
- Absolutes are those which start from absolute zero, which is the lowest theoretical possible temperature and corresponds to the point in which molecules and atoms of a system have the minimum possible thermal energy and are not agitated at all.
- Kelvin (international system): is represented by the letter K and has no grade symbol "º" . It was created by William Thomson, on the basis of Celsius degrees, thus setting the zero point at the absolute zero (-273.15 º C) and keeping the same dimension for grades. It was established in the units’ international system in 1954.
- Relatives are compared to established physical-chemical processes that always occur at the same temperature such as freezing point of nitrogen.
- Celsius Degrees (international system): or also called degree centigrade, is represented by the symbol º C. This unit of measure is defined by choosing the freezing point of water at 0º degrees and the boiling point of water at 100 °, both measurements into a pressure atmosphere , and dividing the scale into 100 equal parts in which each one corresponds to 1 degree . This scale was proposed by Anders Celsius in 1742, a Swedish astronomer physicist.
- Fahrenheit Degrees (international system): this takes divisions between freezing points and evaporation of
solutions of ammonium chloride. So by the proposal of Gabriel Fahrenheit in 1724, he set zero and one hundred in freezing temperatures and evaporation of ammonium chloride in water. It uses a mercury temperature meter by means of introducing a mix of crushed ice with ammonium chloride in equal parts. At the time, the concentrated salt solution was the lowest possible temperature in the laboratory. Then he made another mix of crushed ice and pure water, which determines the point 30 ºF, then setting at 32 ºF (melting ice) and then temperature meters are exposed to steam of boiling water and gets the point 212 ºF (boiling point of water). The difference between the two points is 180 º F, divided into 180 equal parts determines the Fahrenheit degree. Because of this combination of International units of measure the PCE-T395 temperature meters can measure in Celsius or Fahrenheit to accomodate for all situations.
Calibration and certification of temperature meters
An ISO calibration certificate can be acquired for temperature meters. It includes a control document containing the company's contact details consisting on a laboratory calibration and a certification to meet ISO standards. This means that temperature meters meets the minimum requirements of the national body of measurement and it can be included in your internal set of measuring instruments. Further information:
Calibration: Control of measurement magnitudes correction for temperature meters without the intervention in the measurement system, or the determination of the systematic display deviation in relation to the real value of the measuring magnitude.
Calibration certificate: document with the technical properties of the device according to the national organization of measurement.
Calibration interval: to perform correct measurements, devices must be calibrated at regular intervals. This period of time is called calibration interval. It's difficult to determine this period with accuracy but you should consider the following factors:
- Measuring magnitude and allowed margin of tolerance. - Performance of the measuring instruments. - Frequency of use. - Operating conditions. - Previous calibrations stability. - Measuring accuracy required. - Determining factors of the quality control systems used by companies.
This means that the user is in charge to check and control the interval between calibrations. We recommend that this interval between calibrations should be between 1 and 3 years. We can also offer our expert advice to solve any doubts relating to the process of establishing a calibration interval.
