The Santamedical non-contact infrared (IR) clinical thermometer provides a simple, expedient, and accurate way for initial fever screenings by taking the surface temperature of areas on the face such as the forehead or tear ducts. It obtains the body temperature reading with 0.3 degree accuracy in less than 1 second through a click. The IR thermometer features an intuitive guidance system to secure positioning and confirm accurate readings. Temperatures (Fahrenheit or Celsius) are displayed on a huge back-lit LCD screen for easier reading even in total darkness. Adjustable audio alarm will alert you if the temperature is too high. Since there is no contamination risk, one can immediately start again to scan the temperature of other family members or individuals without having to disinfect or changing the tip. It was designed specifically for forehead temperature detection from a 1"-4" (5-15cm) distance with an 89-109 F(32.0-43.0C) temperature range. Unlike other IR thermometers that only measure surface temperature, It is clinically calibrated to convert the forehead temperature reading(external surface) into internal body temperature which is one of the most important vital signs for human being. It can also store 32 temperature readings for future reference. The bright back-lit LCD screen displays readings even in darkness. A sleeping baby or patient will not be disturbed by the thermometer as it is used nor will it cause any discomfort if they are awake. For public health authorities, it provides a simple, quick, Non-contact, and non-invasive way to perform preliminary mass-screening for H1N1 fever (swine flu) infection symptoms (body temperatures above 98.6 degrees Fahrenheit or 37 degrees Celsius). It can take over 100,000 readings on a single set of 2 AA batteries (included). With its rugged, impact and water resistant design, It is able to take over 3,000,000 measurements in the product's lifetime , Fahrenheit readings.
