Product Description LONN-200 series products are medium and low temperature popular thermometers, which adopt the latest invention of our company A series of novel optical components such as optical field converters, photoelectric multi-parameter differential amplifiers, optical filter isolation, and mode stabilizers can determine the temperature of the measured object by measuring the wavelength of the object's radiation wave. In short, it uses the most advanced digital sensing technology to measure the wavelength or wavenumber of the radiation wave of the heating body to represent the temperature value of the measured object. Any object is constantly radiating infrared characteristic waves to space or the surrounding medium, when the temperature rises When , the radiation wave power (wave energy) increases, and the peak wavelength moves to the short-wave direction (the relationship between the peak wavelength of the characteristic wave and temperature can be obtained from Wien's law). The propagation of wave energy is easily attenuated and easily disturbed, while the propagation of wavelength in various media is relatively stable and unchanged. Therefore, it has obvious advantages to measure the temperature value of objects by measuring the wavelength of radiation waves. In practical applications, the advantages of LONN-200 series infrared thermometers are mainly manifested in: simple Easy to use, coaxial laser aiming, no need to adjust the focus during measurement, the diameter of the measured target is greater than 10mm, stronger ability to resist space medium interference (such as smoke, dust, water vapor, etc.), and can measure the surface temperature of the object stably wait. Product advantage ●With its own OLED display screen, the Chinese and English dual menus can be switched freely, the interface is clear and beautiful, and it is easy to use; ●Process parameters can be corrected to compensate for measurement errors caused by various disturbances; ●Unique process temperature correction parameter locking function, only one correction is required to calibrate the process coefficient; ●Coaxial laser aiming, precisely indicating the target to be measured; ●The filter coefficient can be set freely to meet the temperature measurement requirements of different sites; ●Multiple output modes: standard output 4~20mA current signal, Modbus RTU, 485 communication; ●The circuit and software adopt strong anti-interference filtering measures to make the output signal more stable; ●Protective circuits are added to the input and output parts of the circuit to make the system work more stable, reliable and safe; ●Support up to 30 temperature probes in a multipoint network; ●Multi-unit network software under Windows, which can remotely set parameters, read recorded data, and display waveforms.
