Hengaode new analytical thermometer safety instructions and applications
The surface temperature can be determined by measuring the infrared energy radiated from the target surface. Non-contact infrared thermometer uses ultra-low power intelligent design. The ultra-low power design ensures that the product can work for a longer period of time, reducing the troubles of frequent battery replacement and power shortage for users. The intelligent design helps users to more easily test and capture the true value of the measured object more quickly. At the same time, the meter can intelligently select the battery or USB connection for power supply.
Safety instructions
caveat
The warning describes actions that may cause a hazardous situation to the user. To avoid electric shock or personal injury, follow these guidelines:
Do not point the laser directly at the eyes or indirectly reflecting surfaces. Before using the thermometer, please check the case. If the thermometer is damaged, do not use it. Check for damaged or missing plastic parts. When the battery indicator appears, replace the battery as soon as possible. If the thermometer works abnormally, do not use it. The protective measures of the instrument may have been damaged. If in doubt, send the thermometer to be repaired. Do not use the thermometer near explosive gas, steam or dust. To avoid the risk of burns, keep in mind that objects with high reflectivity will usually cause the temperature measurement to be lower than the actual temperature of the object. If the equipment is not used in the manner specified in this manual, the protection provided by the equipment may be destroyed.
Be careful
To avoid damage to the thermometer or the equipment under test, please protect them from the following injuries:
From EMF (electromagnetic field) including electric welding machine, electric induction heater, etc. Static electricity. Thermal shock (caused by large or sudden changes in ambient temperature-wait 30 minutes for the thermometer to stabilize before use). Do not leave the thermometer on or close to hot objects. Various symbols and safety signs on the thermometer and in the manual.
characteristic

1. Single-point laser aiming.
2. Smart USB power supply.
3. Secondary white backlit display (when the USB is connected, the instrument automatically turns on this function).
4. Current temperature plus MIN (minimum), MAX (maximum), DIF (temperature difference), AVG (average) temperature display.
5. The emissivity is adjustable.
6. The trigger is locked.
7. Celsius / Fahrenheit selection.
8. Tripod installation.
9. One 9V battery.
application
In addition to the application fields introduced above, portable thermometer technology has also been widely used in medicine, coal mines, geology, meteorology, oceanography, and scientific investigations.
In medicine, modern medicine proves that many body diseases will cause abnormal body temperature, and these can be detected by infrared camera. Thermal imaging cameras can be used to diagnose breast cancer, because the temperature of the mass is almost always 1 ~ 3 ℃ higher than the temperature of other symmetrical points.
The spontaneous combustion of coal seriously threatens the lives of workers and causes losses to the country ’s coal resources. The cause of the fire was caused by coal oxidation and heating due to air leakage. Generally, the temperature is about 30-200 ° C during the initial oxidation to ignition. Due to the heat transfer of coal, the actual surface temperature is often observed within 100 ° C. Using an infrared fire source detector, it is possible to detect and predict the natural fire in the coal lane.
In the fields of geology, meteorology, oceanography, and scientific investigation, there are many phenomena accompanied by temperature changes. For example: some shallow surface deposits are different from surrounding objects due to the difference in heat capacity and thermal conductivity, reflecting the temperature difference on the surface; some deposits have their own heat released; geothermal and groundwater are reflected to the ground, and the temperature will be higher or lower.
