880C 1616F High Temperature Infrared Thermometer Non-Contact Pyrometer M89BOOTD TesterInfrared Thermometer Non-Contact Pyrometer Thermometer Color LCD Display 880C 1616F Light Alarm Industrial Temperature Measurement ThermometerThis is an industrial temperature measurement that adjusts the reflectivity or sets high or low temperature alarms. Therefore, it is not used to measure the temperature of the human body.

Adjust the emissivity value of the material until the measured temperature is equal to the actual temperature. Emissivity is currently the emissivity of the material.2 materials with lower emissivity cannot be measured by direct measurementUse black tape stick to the surface of the material or spray black paint on the surface of the material (black tape and black paint emissivity is 0.95), when the temperature of the material reaches equilibrium, use an infrared thermometer (the set emissivity is 0.95, 0.1-1.00 adjustable) to measure the temperature of the covering material. Adjust the emissivity of the instrument until the measured temperature is equal to the actual temperature, the emissivity currently is the emissivity of the material. High and low temperature warning1) long press the mode button about 2 seconds to enter the setting page2) set the high temperature warning temperature by the buttons on both sides when the screen shows "Hi".3) short press the mode, then "low" will be displayed on the screen. On this page, you can set the low-temperature warning temperature.4) long press the mode button again to return to the original page. Control CenterShort press "MODE" to switch the device on the original page.-Laser light turns on and offShort press the left "*" button to turn the laser light on or off. Power on and off soundShort press the right button to turn the sound on or off. Sound adjustment1) long press the mode button about 2 seconds to enter the setting page2) short press the MODE button three times, then you can see the horn shown on the scree3) adjust the sound with the buttons on both sides.
