# G. Substantial Equivalence Table

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

Note 1: Compared to the predicate device, the "Measurement range", "Display resolution" and "Measuring accuracy" of the subject device only added the requirement of the Fahrenheit scale. The accuracy requirement of the Celsius scale is the subject device measurement accuracy is in compliance with ISO 80601-2-56 and ASTM E1112 requirements. The differences of display resolution and measuring accuracy will not raise any safety or effectiveness issue.

Note 2: After placing the thermometer on the measurement site, the measured result can only be displayed when the temperature is stable. Generally, the measurement time is not fixed at a certain value, so the measurement speed of the subject device is within 1 minute. The difference of measurement speed will not raise any safety or effectiveness issue.

Note 3: Compared to the predicate device, the subject device can't be turned ON and OFF by shaking it, but it can automatically shut down within 10 minutes. This difference is a functional difference before and after measurement, which has no influence on the accuracy of measurement. The difference in Power ON/OFF will not raise any safety or effectiveness issue.

Based on the comparison chart above, we believe that the T103 and T104 digital thermometer is

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

substantially equivalent to its predicate device cited above and do not raise any new safety and/or effectiveness issues.

# H. Predicate Device Comparison

The subject device and the predicate device have the same intender user, target population, Measurement Site, Components, Sensor and the similar technical parameter; they both use thermistor resistance detection method to detect human body temperature. The subject device and predicate device conform to the same standards. Thus, the subject device is substantially equivalent to the predicate devices.
