Product Introduction
(1) Overview
The JPD-FR302 infrared thermometer (referred to as thermometer
in the following) is a measurement instrument that uses the infrared
receiving principle to measure the temperature in the tympanic
membrane of the earhole. You only need to insert the temperature
probe into the earhole and place it at the correct position, and press
the measurement key to quickly and correctly measure the ear
temperature.
(2) Product Structure
This product mainly consists of a casing, a liquid crystal display, a
press key, a buzzer, an infrared sensor, and a microprocessor.
(3) Measurement Principle
The infrared thermometer uses the infrared temperature sensor to
receive infrared energy emitted by heat generated in the tympanic
membrane of the earhole. The energy penetrates through the lens
and becomes concentrated, and is further converted into a
temperature value by using the thermopile and measurement circuit.
