The Rossmax Infrared Ear thermometer has been carefully devel-
oped for accurate, safe and fast temperature measurements in the
ear.
It is a non-invasive ear thermometer using an infrared detector to
detect body temperature from the auditory canal for adult and
child.
• The quality of the infrared ear thermometer has been veried and con-
forms to the provisions of the EC council directive 93/42/EEC(Medical
Device Directive) Annex I essential requirements and applied harmo-
nized standards. EN 12470-5: 2003 Clinical thermometers-Part 5: Per-
formance of infrared ear thermometers (with maximum device.)
• This thermometer converts the ear temperature to display its “oral
equivalent.” (according to the result of the clinical evaluation)
