## 4. Device Description
The Dual Mode Infrared Thermometer (Model DM-IR200) is a hand-held, non-sterile, reusable, battery powered device designed to measure human body temperature via one of two body sites: the ear canal or skin of the forehead.
The DM-IR200 thermometer utilizes infrared technology to measure the natural thermal infrared energy emitted from the surface of the forehead or from the eardrum tissue.
## 5. Indications for Use
The Dual Mode Infrared Thermometer (Model DM-IR200) is intended for the intermittent measurement and monitoring of human body temperatures. It is for non
{4}------------------------------------------------
professional use by consumers at home. The ear canal mode is indicated for use by people above one year old and the skin/forehead mode is indicated for use by people of all ages.
#### 6. Comparison to Predicate Devices and Substantial Equivalence
The Dual Mode Infrared Thermometer (Model DM-IR200) is substantially equivalent to the predicate devices, which uses the same fundamental technology, is similar in design and has the same intended use.
The proposed device and predicate devices all utilize an infrared technology to measure natural infrared energy emitted from the skin surface of the forehead or from the eardrum tissue.
The proposed device and predicate devices are intended for the intermittent measurement and monitoring of human body temperatures by detecting body temperatures from the forehead or auditory canal. The proposed and predicate devices are designed for nonprofessional use by consumers at home. The intended population of the proposed device is all ages for the forehead mode and above one year old for the ear mode. There is a minor difference with the predicate devices with intended population of all ages.
The proposed and predicate devices mainly differ by the measurement range, memory sets, power supply and storage condition. A side-by-side comparison of the proposed device and the predicate device is included in the 510(k) submission.

Guidance document includes the FDA Guidance on the Content of Premarket Notification 510(k) Submissions for Clinical Electronic Thermometers.
#### 8. Clinical Testing
A clinical study was performed to determine the clinical accuracy and to provide comparison with predicate device. The three groups of subjects being tested were: 1) infants under 1 year old, 2) children between 1 and 5 years old, and 3) patients over 5 vears old.
The study included 105 subjects, with 33.3% febrile subjects. For each age group, the ratio of febrile subjects was more than 30%. The study excluded subjects with medical conditions such as inflammation at the measuring sites and subjects using medications known to affect body temperature. From each test site, a total of 105 data sets were collected.
The clinical accuracy of the proposed device was evaluated by determining two kinds of errors in accordance with requirements of ASTM E1965 - clinical bias with stated uncertainty and clinical repeatability. The clinical test results showed that there is substantial clinical agreement and repeatability between the proposed device and
{7}------------------------------------------------
predicate devices. The calculated clinical bias did not exceed 0.06°C, with uncertainty that did not exceed 0.02°C. The clinical repeatability was 0.1°C.
#### 9. Conclusion
The Dual Mode Infrared Thermometer (Model DM-IR200) has the same intended use and similar technological characteristics as the predicate devices. In addition, compliance with applicable voluntary standards, as well as performance testing demonstrate that any differences in technological characteristics do not raise any new questions of safety and/or effectiveness. Therefore, we conclude that the Dual Mode Infrared Thermometer (Model DM-IR200) is substantially equivalent to the predicate devices.
