## 5.0 Device Description

The Infrared Thermometer, Models RN-60A and RN-60B are hand-held device powered by 2*AAA batteries and designed to measure human body temperature without contacting patient' forehead.

The Infrared Thermometers RN-60A and RN-60B measure the temperature by using the principle of receiving infrared. An object with a temperature higher than absolute zero will radiate a certain amount of infrared energy. According to the infrared energy and wavelength, the surface temperature of the object can be determined. The temperature of human forehead is relatively constant, so the temperature of human forehead can be measured according to this principle. The thermometer adopts a new CMOS compatible thermopile sensor with good sensitivity. The pressure difference generated by the sensor after receiving the infrared signal is amplified and analyzed then display on the LCD screen in digital form.

The measurement distance of the subject device is 3~5 cm from the forehead.

The only differences among the RN-60A and RN-60B thermometers are size, weight, shape of enclosure.

#### 6.0 Indication for Use Statement

The Infrared thermometer is a non-contact infrared thermometer intended for the intermittent measurement of human body temperature from forehead for people of one month old and above. The device is reusable for home use and clinical use.

## 7.0 Comparison to the Predicate Device

{5}------------------------------------------------

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

## Analysis:

From the comparison table, the subject devices and predicate device have the same measurement place, display resolution, display screen, auto power-off while no operation and conformance standard. There are slightly differences between the devices and predicate device as follows:

Different 1:The restriction in use for people of one month old and above, that is the subset patient population of the predicate device, thus no new safety and

effectiveness concerns raised due to the difference.
