Overview

TH520 Multi-function Infrared Thermometer

TH520 Multi-function Infrared Thermometer

The TH520 is an electronic infrared thermometer designed for home use, capable of detecting body temperature from the ear canal and forehead, as well as surface temperatures. It is suitable for individuals of all ages.

Function Description

The thermometer utilizes an infrared detector (thermopile detector) to measure temperature. It offers three primary measurement modes: Ear, Forehead, and Surface, along with a built-in Stopwatch function.

Real-Time Clock: The device includes a real-time clock that records the date and time (12/24-hour format) for each measurement, aiding in tracking and recognizing results. This function must be set up during the first use.

Room Temperature: After the real-time clock is set and the device is powered off, the room temperature is displayed on the screen with a dedicated icon. This feature helps users recognize the ambient temperature, which is important for infants and patients.

Ear/Forehead Temperature: This mode measures body temperature. For ear measurements, the probe is gently positioned into the ear canal, aiming towards the eardrum. For forehead measurements, the thermometer is held within 1 cm of the central forehead. The device converts forehead temperature to an "oral equivalent" value. It is important to compare results with regular body temperature and consult a doctor for health concerns.

Surface Mode: This mode displays actual, unadjusted surface temperatures. It is useful for monitoring the temperature of objects, such as a baby's milk, to ensure it is suitable for the baby or patient. The reading updates continuously when the "FOREHEAD" button is pressed and held.

Stopwatch: A built-in stopwatch function helps monitor heartbeat, a key health index. It counts in 0.01-second increments up to 3 minutes.

Fever Indication: If the thermometer detects a body temperature of 37.5°C or higher, it will emit a long beep followed by three short beeps to alert the user to potential fever.

Memory Locations: The device stores up to 9 sets of body temperature measurements. Each memory entry includes the measurement date, time, mode icon, and site location. These can be accessed by pressing the "ON/MEM" button when the device is powered on.

°C/°F Switch: In power-off mode (when only date, time, and room temperature are displayed), users can switch between Celsius (°C) and Fahrenheit (°F) by pressing and holding the "FOREHEAD" button, then immediately pressing and releasing the "ON/MEM" button.
