Pyrometers and thermal imagers: Measure surface temperature quickly and without contact

Temperature is a very important measurement parameter in industry, science and research. Infra-red (IR) thermometers allow simple non-contact measurement of the surface temperature in many applications. The combination of infra-red thermometer and penetration thermometer allows the simultaneous measurement of surface and core temperature. The infra-red thermometer offers the following features, among others:

  • Fast, non-contact measurement of surface temperatures
  • Easy measurement in places that are difficult to access
  • A solution to measurement on moving equipment for the most stringent requirements

Pyrometers: For single-point temperature measurements

An infrared thermometer is ideal for fast temperature checks. Particularly practical: The combination of pyrometer and penetration thermometer allows the simultaneous measurement of surface and core temperature.

The pyrometer offers the following features, among others:

  • Fast, non-contact measurement of surface temperatures
  • Easy measurement in places that are difficult to access
  • Precision technology for the most stringent requirements
  • Reliable temperature measuring instrument

Measuring temperature with an infra-red thermometer

The infra-red thermometer is considered to be an optimally usable and versatile temperature measuring instrument. The parameters emissivity and distance or measurement spot must be taken into consideration. To ensure safe use of the infra-red thermometers, Testo stores an emissivity table in each instrument, which can be used to quickly set the emissivities to suit the product being measured. In addition, the distance to the measuring spot is lying on the measuring object plays a role: to ensure accuracy, the person measuring must be far enough awa ythat the entire extent if the measurement spot is lying on the measuring object. The further away you are from the measuring object, the larger the measurement spot will be.

 

It is also important to choose the right infra-red thermometer, Here you should ask yourself in advance what you need this type of temperature measuring instrument for. Is it sufficient to measure the surface temperature or is it also necessary to determine the core temperature? If it's a case of the latter, then a combined pyrometer/penetration thermometer is the appropriate choice. It is also important as to whether the data is to be transferred to a mobile device. For example, Smart Probes offer the option of transmitting the measurement data from the respective measuring instrument to the Testo Smart Probes App - either as a diagram or in tabular form.

 

The following aspects are also relevant when it comes to measuring temperature with a pyrometer:

  • Measurement spot size (measuring range depends on the distance to the measuring object)
  • Ambient temperature
  • Surface to be measured - emissivity value for the material
  • Additional contact measurement necessary

Infrared thermometer: Accurate measurement at a distance

Infra-red thermometers (pyrometers) allow non-contact surface temperature measurements to be performed. In many cases, it is important to identify individual temperature spots and to determine whether an object is heating or cooling. Even measurements at hard-to-reach locations or far away measuring points are no problem.

Laser thermometers: For the toughest of applications

Infra-red thermometers offer a reliable and simple way to measure surface temperature of many products, materials, or equipment. Products such as the testo 835-T2 can offer measurement ranges up to 1500 °C and down to -50 °C.

Many of the Testo range of IR thermometers also have functionality allowing the user to pre-set audible and visual alarm conditions which can provide users with a simple way to confirm if a subject is within expected temperature guidelines or range.

Temperature measuring instrument: For use with a smartphone

Is there really such a thing as a temperature measuring instrument that carries out accurate measurements and also offers the option of transferring the data to a smartphone? There certainly is, because Testo has been offering this kind of measuring technology for a long time. Various thermometer and measuring instruments for other values can be used in the form of a Smart probes kit.

The measured values are transferred to the app on the smartpgone so that the data can be viewed and evaluate at any time. Another way to measure surface temperature without actual contact is to use a thermal imaging camera. With a Testo thermal imaging camera the user can both get a spot temperature measurement, but also more importantly a visual representation of the surface temperature as an image. Thermal imaging can be used in applications within HVAC, industrial maintenance, Facilities maintenance,as examples.
