4-in-1 Rechargeable Contact Infrared Thermometer

Temperature monitoring requires more than fast measurement—it also requires consistent operation, easy reading, and reliable daily performance. The COCET KFT-28 is a 4-in-1 Rechargeable Contact Infrared Thermometer developed for families, caregivers, and healthcare users who need a reusable temperature measurement solution. It combines forehead, ear, object, and environment temperature measurement functions in one compact device, helping users manage different temperature checking scenarios with a single thermometer.

Powered by a rechargeable 200mAh Li-ion battery and equipped with a high-contrast LCD display, the device reduces the need for frequent battery replacement while maintaining convenient operation. Its contact infrared sensing system provides quick temperature readings with stable accuracy, making it suitable for home healthcare, pediatric care, elderly monitoring, and professional medical distribution channels.

Designed for Daily Temperature Management

Easy Operation Process

The KFT-28 adopts a simple operating structure that allows users to complete temperature measurement with minimal steps. The device integrates measurement control, display reading, and mode switching into an intuitive interface, making it easier for different age groups including elderly users and caregivers to operate.

Instead of complicated settings, users can quickly select the required measurement mode and obtain temperature data through the LCD screen. The straightforward operation design helps reduce errors during repeated daily measurements.

Multiple Applications in One Device

Unlike traditional thermometers designed only for body temperature measurement, this model supports four application scenarios: ear temperature, forehead temperature, object temperature, and environment temperature. This allows users to check personal health conditions while also monitoring surrounding temperatures such as baby food, bath water, or room conditions.

The multifunctional structure makes the 4-in-1 Rechargeable Contact Infrared Thermometer suitable for households, childcare environments, nursing facilities, and healthcare distributors looking for a versatile temperature monitoring product.

Clear Data Reading Experience

The KFT-28 uses a 26mm × 13mm LCD display with clear numerical presentation. The large digits allow users to quickly identify temperature values without requiring complex interpretation. The dual-scale function supports Celsius and Fahrenheit switching, making the device adaptable to different market requirements.

A memory function storing up to 32 temperature records helps users review previous measurements, which is useful for monitoring temperature changes over time and supporting communication with healthcare professionals.

Rechargeable Structure for Repeated Use

The built-in 200mAh Li-ion battery provides a convenient charging solution compared with traditional disposable battery-powered thermometers. The TYPE-C charging interface allows easy connection with commonly used charging cables, reducing maintenance requirements for users and distributors.

With approximately 800 measurements per full charge and up to 500 charge-discharge cycles, the rechargeable design supports long-term daily usage while reducing battery replacement frequency.

Performance Verification

Temperature Accuracy Test

Each KFT-28 device is tested for temperature measurement accuracy before shipment. The testing process verifies infrared sensor performance, measurement stability, and temperature deviation within the specified range.

The thermometer provides an accuracy of ±0.2℃ (±0.4℉) under the standard forehead and ear temperature measurement range of 35.0℃ ~ 42.0℃ (95.0℉ ~ 107.6℉), ensuring reliable temperature monitoring performance.

Battery and Charging Test

The rechargeable power system is tested to confirm charging performance, battery operation stability, and continuous measurement capability. The TYPE-C charging port is checked for connection reliability, while the battery capacity is verified to support approximately 800 measurements under standard conditions.

Display and Function Test

The LCD display, temperature mode switching, memory storage, automatic power-off function, and Celsius/Fahrenheit conversion are tested during production inspection. These tests ensure every unit provides consistent operation before delivery to customers.
