FANMI Infrared Thermometer Pro Dual Use Non Contact infrared thermometer

The FANMI Infrared Thermometer Pro features the following main specifications derived directly from manufacturer details:

Technical Specifications

• Brand / Manufacturer: Fanmi 
• Product Category: Dual-use non-contact infrared thermometer (forehead and ear mode)
• Probe Design: Patented 3D probe automatic sensing with a 30° ergonomic angle for comfortable positioning.
• Sensor Core: European high-end matrix sensor probe.
• Power Supply: 2x AA standard dry batteries (designed with external batteries rather than built-in cells to prevent device-aging during long storage periods).

Performance & Operation

• Measurement Speed: Instant 1-second read.
• Measuring Distance: Optimal range of 1 to 3 cm away from the forehead or temporal area.
• Accuracy: Internal hospital-grade matrix sampling up to ±0.2°C (±0.4°F) within clinical human temperature bounds.
• Display Interface: Vertical minimalist design with a large LED backlight matrix screen (displays stark white characters, making it highly readable in completely dark rooms).
• Fever Alert Protocols:
    • The LED interface alters color based on readings (e.g., changes from standard white to a red flashing indicator when an abnormal temperature is detected).
    • Acoustic buzzer beeps kick in when a high fever threshold is passed (exceeding 38°C or critical limits above 42°C).
• Power Management: Smart auto-sensing toggle that automatically triggers a shutdown sequence after 30 seconds of inactivity to maximize battery life.

Final Physical Check Recommendation

Please make sure to double-check your physical user manual located inside the device box. Operating parameters can vary slightly depending on regional regulatory variants (such as specific regional units set natively to Celsius vs. Fahrenheit).

Battery Specifications

• Battery Type: Requires 2 × AA standard dry batteries (alkaline batteries are strongly recommended for consistent voltage).
• Operating Voltage: DC 3.0V (each battery supplying 1.5V).
• Battery Longevity: A fresh pair of AA alkaline batteries delivers approximately 1,000 temperature measurements before needing replacement.
• Low-Power Indicator: The minimalist matrix screen features a low-battery alert icon that activates when the cumulative voltage drops below 2.5V (±0.2V), reminding you it is time to switch the cells.

Wattage & Power Consumption

Medical infrared thermometers are designed as ultra-low power consumption devices to ensure safety and longevity:
• Operating Wattage: Consumes between 30 mW to 45 mW during active sensor sampling.
• Standby Current Consumption: Draws negligible static current microamps (≤ 30 μ A) while asleep, which safely prevents battery drain between uses.
• Auto-Off Trigger: To conserve power, the system automatically cuts off completely after 30 seconds of inactivity.

Note on Rechargeable Batteries

It is recommended to avoid 1.2V NiMH rechargeable batteries. Standard NiMH rechargeable output a lower native voltage (2.4V total), which can prematurely trigger the device's built-in low battery safety cutoff.
