- firstly, i am interested because prices of common high end infrared digital thermometers costs around 3X and over compared to your merchandise, so, i would say it is a good buy for technical enthusiasts.
- secondly, in answer to your question, living "human body" temperature can only range from about 36deg Centigrade to about 41deg Centigrade, because higher or lower than that, one could be dead in a few hours or so, (hyperthermia/hypothermia)... industrial process temperature measurements on the other hand varies very widely in its range and application from different medium such as process piping (with any fluid) made of plastics, steel, alloy, glass, etc., and maybe furnace or furnace wall temperatures, direct media measurements, etc... each require different emissivity settings for different kind of materials which your laser pointer is fixed (Emissivity: 0.95 fixed)...
- thirdly, definitely i know that your instrument can measure the "human" body temperature, but my point is the ACCURACY... because if you notice "old school" mercury and kerosene filled thermometers, and digital thermocouple type body thermometers sold at drugstores, those have limited ranges at 34deg C ~ 42degC, which made it more accurate (±0.1 degC or better) compared to what yours have which has a range of -50degC ~ +380deg C with accuracy of ±2 degree / centigrade and Fahrenheit...
- to illustrate my point: if one's body temperature is measured using "old school" thermometers or digital thermocouple types with accuracy of ±0.1degC and is reading 36.8degC, it could probably be more or less 0.1degC, meaning 36.7 or 36.9... whereas, using your "laser" (infrared) type thermometer with accuracy of ±2 degree / centigrade and Fahrenheit on the same human body it could be 34.8 or 38.8 degC...., at 34.8 one could be at hypothermia stage, while at 38.8 one is having fever...
- industrial and process applications have very wide range and for certain purposes say, if one wants to measure a bare steam condensate pipe temperature closed normally but wants to check for valve leak thru, 96degC and 98degC, or ±2deg difference doesn't make much of an impact, but confirms the leakage...
- hope above explanation clarifies my point, and thank you for the reply....
