Contactless thermometers

Contactless infrared thermometers, or pyrometers are devices, which determine the temperature or the measured object from temperature radiation.

They are used to measure temperatures predominantly within the range -50°C up to +3500°C.

Among advantages of the devices can be cunted:

• measuring speed (withing the range of miliseconds) - saves your time and enables to carry out much more measurements,
• enables even measuring of moving objects,
• easy temperature measuring on dangerous or hardly accessible places (parts under high voltage, moving parts, distant objects),
• trouble-free measurng of very high temperatures (over 1300 °C). In these cases is almost impossible to use contact thermometers, as they usually have very limited lifespan,
• the measured object is not being influenced (there is no energy draw at measuring. For instance when we are measuring low temperature conductors e.g. plastic or wood, the measuring by contactless thermometer are very accurate and without distortion or measured values in comparison to the contact theromometers.
• the measuring takes place without any peril of contamination and mechanic effect on the surface of the measured object (e.g. scratching of painted surfaces and it enables to measure even soft surfaces. Measuring in food industry is perfectly hygienic and safe).

IR contactless thermometer GM550E

Features:

• unit selection °C or °F
• freeze (holding) of the value on the display
• laser pointer

  What is the use of laser pointer?

  Infrared thermometers are frequently equipped by laser pointer, which enables the user to aim the measured spot much faster and more accurate.

  Simple laser beam with a shift from optical axis
  The laser beam comes out of the place away from the middle from the optic axis and does not correspondent with the optical axis. This is the simplest version, used mainly for devices with low optic definition (for large easured objects). The laser beam must be aimed approximately into the middle of the measured object, but within small distances can be spotted some inacurracy.
• display backlight

Parameters:

• temperature range: -50 ~ 550°C (-58 ~ 1022°F)
• accuracy: ±1,5% from the value or ±1,5°C
• optical resolution:

  What is optical resolution?

  Optical system of infrared thermometers catches infrared energy from circular measured surface and concentrates it to the detector. The measured object must fulfill the measured surface, otherwise the thermometer "sees" other temperature radiation from the background, which causes inacurracy of measured values.

  Optical resolution D : S is defined as a relationship between the distance of measuring device and measured object, and the diameter of the measured surface. The bigger the value is, the better is the optical resolution of measuring device is and the smaler can be the measured surface at the given distance.

  What is emisivity?

  The emisivity determins the ability of the object to radiate temperature. It is dimensionless unit.  Overview or emisivity of selected materials:
