#### Comparison to Predicate Device 6.

{6}------------------------------------------------

# Note 1

The Intended Use of subject device and predicate device is non-contact measurement of human body temperature from the forehead. The target population of the subject device is a subset of the predicate. This difference does not raise new or different questions of safety and effectiveness.

# Note 2

Measurement time of the subject device is ≤3 seconds, the predicate device is 1 second. Both the subject and predict devices comply with ASTM E 1965-98. It is demonstrated that Page 4 of 7

{7}------------------------------------------------

the measure time does not affect the measurement accuracy. This difference does not raise new or different questions of safety and effectiveness.

### Note 3

Measurement distance of the subject devices is 2-5cm, the predicate device measurement distance is 5- 8cm (models HW-2/HW-2S/HW-3/HW-302/ HW-303) or 1-2cm (models HW-4/HW-4S). Performance testing of the of the subject device demonstrates the accuracy meets the requirements within the distance range. The difference does not raise new or different questions of safety and effectiveness.

### Note 4

Both devices have different measurement ranges; however, the measurement range of the subject device meets the requirements of ASTME1965-98. Therefore, the difference does not raise new or different questions of safety and effectiveness.
