Virax Mini VISIOVAL Manuel D'utilisation page 24

NOTE: Where the human eye can look through glass, glass has a reflective property to
infrared radiation. Your Thermal Imager therefore measures thermal radiation reflected off the
glass, and cannot detect temperature of viewed materials from behind the glass.
NOTE: Where the Thermal Imager will always visually indicate temperature variations through
the user's choice of color pallets, the accuracy of actual temperature readings may vary when
viewing a variety of object with varying color and texture. Remember – every surface has a
specific Emissivity for optimum accuracy of temperature readings.
Optimum conditions for taking a thermal reading are:
• (outdoors) stable weather conditions / cloudy sky before and during the measurement
• (outdoors) no direct solar radiation before and during the measurement
• (indoors / outdoors) dry conditions / no precipitation
• (indoors / outdoors) clean surfaces
NOTE: Your VIRAX Thermal Imager is factory calibrated with an optimum focal range of 2 m,
which maximizes the thermal overlay properties and image alignment with that of the visual
properties of the camera. This was determined based on the typical indoor work environment
of the plumber.
