Instructions for use of special infrared thermometer for aluminum measurement
The working principle of the special infrared thermometer for measuring aluminum is to calculate the surface temperature of the object according to the infrared radiation intensity of the object. The biggest feature of the infrared thermometer is that it can measure the temperature of the object without contact. Therefore, it can conveniently measure the temperature of inaccessible or moving targets. The infrared thermometer uses a 2-level laser for coaxial aiming, which can conveniently indicate the center position of the measurement point, and especially mark the best measurement distance, which is suitable for the temperature of small targets that need fixed-point measurement. The infrared thermometer provides a two-wire 4-20mA current output, which can be easily installed in a variety of applications, especially suitable for installation in industrial environments that require long distances and strong interference. The infrared thermometer provides different wiring methods for the laser circuit and the measurement circuit, which is convenient for users to use. A full range of infrared thermometers provide a variety of temperature ranges, different measurement wavelengths, and different optical coefficients for users to choose to meet different measurement requirements of users. The infrared thermometer has an on-site emissivity adjustment function, which is convenient for users to make on-site corrections for different measured targets, and improves the effectiveness and authenticity of the measurement results.

Laser and emissivity buttons
Press the button to perform laser switch function and emissivity setting function
Temperature measurement status
Normal temperature display: 888.8°C/8888°C
When the target temperature exceeds the upper limit of the measurement temperature: display the measurement upper limit temperature
When the target temperature is lower than the lower limit of the measurement temperature: display the lower limit temperature of the measurement
use of laser
Each time the button is pressed, the probe performs the laser on and off operation, and the indicator light next to the switch will work at the same time. After the laser is turned on, it will automatically turn off in about 4-5 minutes.
emissivity setting
Press the button for 3 seconds to enter the emissivity parameter setting state.
Displays the current emissivity value, the value on the thousandth digit flashes, and every time the button is pressed, the value of the standard digit is increased by one and the cycle is performed. The other digits remain unchanged.
Press the button for 3 seconds to enter the percentile setting of the emissivity parameter, and the value on the percentile of the emissivity value will flash.
Each time the button is pressed, the value of the standard position is increased by one and the cycle is performed. The other digits remain unchanged.
Press the button for 3 seconds to enter the setting of the integer and tenth place of the emissivity parameter, and the value on the integer and tenth place of the emissivity value flashes.
Each time the button is pressed, the value will be incremented by one and the cycle will be performed, and the range is 0.1—1.0. The other digits remain unchanged.
Press the button for 3 seconds to complete the emissivity parameter modification and resume measurement.
emissivity
Determine the emissivity of an object
The intensity of infrared radiation emitted by an object depends on the temperature of the object and the radiation characteristics of the material on the surface of the object. We use the parameter emissivity (ε-Epsilon) to describe the ability of an object to radiate energy outward. Emissivity values can range from 0 to 100%. The "black body" we usually say refers to an ideal radiation source with an emissivity of 1.0, while the emissivity of a mirror is generally 0.1. If the emissivity selected for measuring temperature with an infrared thermometer is too high, the temperature displayed by the thermometer will be lower than the true temperature of the target being measured - assuming that the temperature of the target being measured is higher than the ambient temperature.
Objects with low emissivity (reflective surfaces) have measurement errors due to interference from other external radiation or background objects (flames, heating systems, refractory materials). To reduce measurement errors in this case, install and protect the probe very carefully Keep away from sources of reflected radiation.
