DIT colorimetric thermometer Introduction: The DIT colorimetric thermometer uses a two-color temperature measurement method, that is, the energy ratio of the two infrared bands radiated by the target object to determine the temperature of the measured object. Since the measurement result depends on the ratio of the radiated power of the two bands, the partial loss of the radiant energy has no effect on the measurement result. It can overcome the measurement error caused by the radiation medium attenuation caused by dust, smoke, water vapor, partial occlusion of the field of view and measurement distance variation, especially suitable for relatively harsh temperature measurement environment. During metal hot working, the metal surface is inevitably oxidized rapidly to form an oxide layer. The oxide layer will fall off or split with temperature (for example, a steel rolling line), and the split oxide scale and the metal body form a gap, so that the temperature of the oxide layer is lower than Metal body temperature. The two-color thermometer can well overcome the measurement error caused by it. The production process data is reliable and discrete, which is convenient for process analysis. Colorimetric temperature measurement also has advantages for vacuum or shielding gas heating systems, which can overcome the measurement error caused by the glass window material and make the measured value closer to the true value. The DIT colorimetric thermometer has a visual sighting system that is very user-friendly and allows you to see if the thermometer is aimed at the target in real time. For a sealed environment measurement system, visual sighting can also be used as an observation window for furnace conditions. The DIT colorimetric thermometer has a wealth of features, real-time highlight temperature measurement display, user selectable measurement mode, measurement mode, temperature measurement speed, and output specification settings. Fully meet the customer's various field use needs. Human-computer interaction is simple and convenient. In the process of using a monochrome thermometer, the measurement error caused by the following reasons may be encountered: 1. The surface state of the material oxidation changes, or the oxide and the original material crack, causing a large measurement error. 2. The measurement error caused by the low emissivity of the material itself. 3. Measure the measurement error caused by harsh environment (dust, smoke, water vapor, etc.). 4. The measurement aperture cannot fully meet the measurement error caused by the field of view of the thermometer.
