Non-Contact Infrared Thermometer

The BONAEVER W-HT-820D is a handheld infrared thermometer designed for household use. It measures body temperature from 32.0 to 43.0°C and surface temperature from 0 to 100°C without physical contact. The device suits parents, carers and anyone needing quick, hygienic temperature checks at a measuring distance of 5 to 15 cm.

Three-Colour Backlit Display

A 1.9 inch LCD shows readings with a resolution of 0.1°C and changes colour to indicate fever level. Green appears below 37.5°C, orange between 37.5 and 38°C and red above 38°C. The unit stores the last 34 measurements for trend tracking and powers off automatically after 7 seconds to save the two 1.5 V batteries, which are not included.

Clinical Accuracy With Calibration

Body readings are accurate to within ±0.3°C while surface readings stay within ±1°C, with a response time of 0.5 seconds. The thermometer operates up to a maximum measuring temperature of 49°C and can be calibrated if required. It is not suited for users who need continuous monitoring, data export or an included power source.

Questions about this item

How often do the two 1.5 V batteries need replacing with all-day use?

The thermometer powers off automatically after 7 seconds of inactivity, so the two 1.5 V cells last through many days of repeated 0.5-second readings.

What is the highest temperature the W-HT-820D can measure before it stops reading?

The infrared sensor tops out at 49 °C for surface measurements, and the body mode stops at 43 °C.

Does the backlight colour change add noticeable heat or noise during continuous checks?

The three-colour LCD backlight is purely visual; the handheld plastic body stays cool and silent during 0.5-second scans.
