infrared thermometers

Descripción del producto

Product classification: Sort as usage type:B 2. Principle of work Any object at above zero centigrade can generate certain proportion of infrared radiant energy as per its own temperature. The radiant energy and its wavelength distribution are subject to its surface temperature. Body temperature (*6~*7°C) can release infrared ray at 9~*3um. Based on this principle, precise body temperature can be calculated from difference between forehead temperature and body temperature tested by infrared-ray thermometer. 3. Characteristics l Voice report for testing result is more smart and prompt. l It is designed to test forehead temperature, which can adjust according to environmental temperature and forehead temperature. l It adopts high-precise infrared sensor and has reliable performance; l It has the function to prompt over-high temperature (the value can be set in advance); l It can save *4 testing figures automatically; l LCD display l Fahrenheit and centigrade is available; l Object temp Mode can be used to test object at 0~**0°C having emissivity in 0.*5; l Lock automatic scan testing function; l Automatic switch-off function to save energy. 4. Key technical parameter Working environment Environmental temp:*6°C~*5°C Relative temp: ≤*5% Power supply: DC3V (two AA batteries) Size **0mm×*3mm×**2mm (L*W*H) Weight **7g (excluding battery Resolution 0.1°C Testing scope Body temp: *2.0°C~*2.0°C (*9.6~**7.6°F) Object surface temp: 0°C~**0°C (*2.0~**2.0°F) Power consumption Voice prompt: ≤*0mw No voice prompt: ≤*0mw Testing tolerance ≤±0.3°C Testing repetitiveness ≤±0.2°C Testing time ≤0.5s Testing distance *0mm***0mm Emissivity 0.*5 Automatic switch-off time *0 s Save amount *4
