Information

With technology and continuous development, the advancement of infrared thermometer technology has provided users with a variety of functional and multi-purpose instruments, expanding the choice. When choosing a thermometer model, you should first determine the measurement requirements, such as the temperature of the target to be measured, the size of the target to be measured, the measurement distance, the material of the target to be measured, the environment of the target, the response speed, the measurement accuracy, whether it is portable or online, etc. ; In the comparison of existing thermometers of various models, select the instrument model that can meet the above requirements; choose the best match in terms of performance, function and price among many models that can meet the above requirements. Other options, such as ease of use, maintenance and calibration performance, etc.

High temperature pyrometer manufacturers


(1) In the case where high transmittance is required and the wavelength range is wide (2μm~18μm), the window can be at a temperature lower than 100 °C, it is best to choose a germanium material window with an antireflection coating, and the transmittance can be up to 95%.

(2) If the working wavelength is 8~14μm and the wavelength visible to the naked eye is required, it is best to use the window of ZnSe or BaF2 material.

(3) It is best to use a window made of fused silica when the working wavelength is below 2.2 μm. Environmental factors, such as atmosphere, vacuum, etc., should also be considered when selecting windows.
(4) Correction method for the influence of window transmittance on temperature measurement results: Generally, the window transmittance is less than 100%. At this time, the emissivity of the measured object should be multiplied by the window transmittance to compensate for the energy loss caused by passing through the window.
