Summary: DIT colorimetric thermometer: the temperature of the measured object is determined by the energy ratio of two infrared bands radiated by the target object. Since the measured results depend on the ratio of the radiated power of the two bands, the partial loss of radiated energy has no effect on the measured results. It can overcome the measurement error caused by the attenuation of radiation energy caused by dust, smoke, water vapor, local occlusion of the field of view and the change of measuring distance. It is especially suitable for relatively harsh temperature measurement environment. During hot metal processing, the metal surface will inevitably rapidly oxidize to form an oxide layer, which will fall off or crack with the change of temperature (such as steel rolling line), and the gap between the oxide skin and the metal body forms, making the temperature of the oxide layer lower than that of the metal body. The two-color thermometer can overcome the measurement error. This makes the data of production process reliable and less discrete, which is convenient for process analysis. Colorimetric temperature measurement also has advantages for vacuum or protective gas heating system, which can overcome the measurement error caused by glass window material and make the measured value closer to the true value. DIT colorimetric thermometer has visual aiming system, which is very convenient for users to install and check whether the thermometer is aimed at the target in real time. For the measuring system of the sealing environment, visual aiming can also be used as the observation window of the working condition in the furnace. DIT colorimetry instrument has rich functions, real-time highlighting temperature measurement value display, users can choose measurement method, measurement mode, temperature measurement speed and output specification setting. Fully meet customers' requirements for on-site use. Human-computer interaction is simple and convenient. In the process of using monochrome thermometers, the measurement error caused by the following reasons will be encountered: 1. The oxidation surface state of the material will change, or large measurement error will be caused by the oxide and the original material cracking. 2. Measurement error caused by low emissivity of the material itself. 3. Measurement error caused by poor measurement environment (dust, smoke, water vapor, etc.). 4. The measurement error caused by the fact that the aperture of the measurement hole cannot fully meet the field demand of the thermometer.
