Temperature measurement does not need to be intrusive and upsetting to patients. With the Febris® Touch-Free Technology, simply point towards the forehead and you'll get an instant and accurate reading. So say goodbye to the old fashioned methods (rectal, oral, ear, and axillary) that can often be inaccurate and distressing to feverish patients, especially fussy babies. The easy-to-use design also stores up to 10 prior measurements with averages so you can track your temperature readings over time. With Touch-Free Technology there is no contact with the patient, so it is perfectly hygienic and eliminates cross-contamination. And since there is no need for probe covers, there is no more waste, so it's better for our environment. Batteries: 2AAA (included) Product ID: ThermMDF
