Clinical Features & Benefits

  • Instant 1-Second Readings: Infrared technology captures the core body temperature via the tympanic membrane almost instantly.
  • Fever Alarm: Features a built-in audible alarm that alerts the user when a temperature higher than 99.5°F (37.5°C) is detected.
  • 12-Reading Memory: Automatically stores the last 12 readings, allowing you to track the progress of a fever and share data with healthcare providers.
  • Large Backlit Display: The clear LCD screen is easy to read in low-light conditions, perfect for nighttime temperature checks without disturbing the patient.
  • Hygienic Operation: Designed to work with disposable probe covers to maintain a sterile environment and prevent the spread of germs.

Professional Precision for Home Health

The Adtemp 421 is a favorite among pediatricians and home caregivers because it combines hospital-level accuracy with an intuitive interface. Whether you are managing post-operative recovery, a seasonal flu, or chronic health monitoring, having a reliable thermometer is a vital part of your medical toolkit. Its compact, ergonomic shape fits comfortably in the hand, and the simple one-button operation makes it accessible for users of all experience levels.

Built by American Diagnostic Corporation (ADC), this thermometer is constructed to meet rigorous international standards for safety and performance. It includes an auto-off feature to preserve battery life and can toggle between Fahrenheit and Celsius with a simple adjustment, ensuring it meets your specific preferences.


Frequently Asked Questions (FAQ)

Why is ear measurement more accurate?

The eardrum (tympanic membrane) shares the same blood supply as the hypothalamus, the brain's temperature control center. This allows the Adtemp 421 to reflect core body temperature more accurately than oral or skin-surface measurements.

Does it require probe covers?

Yes, to ensure maximum accuracy and hygiene, it is recommended to use a fresh disposable probe cover for every reading. This also protects the infrared lens from earwax buildup.

Is this suitable for all ages?

While highly effective for adults and children, tympanic thermometers are generally recommended for infants over 6 months old once the ear canal has fully developed.

Color not as pictured
Color: Purple, Size: Small
Love the top but the color is not even close to what is pictured. Ordered purple, the package label says it's purple, but it is bright hot pink.

Supportive, Comfortable & Super Flattering
Size: 42DD, Color: White
I’m really impressed with this bra! It offers great support while still feeling comfortable enough to wear all day. The fit is flattering and smooth under clothes, and I love that it provides full coverage without feeling bulky. The material feels soft and well made, and the underwire gives just the right amount of lift and shape. It’s a great everyday bra that actually looks and feels good on, definitely a win!

Absolutely Love!
Size: 40D, Color: Warm Beige
I lost some weight and wanted a new bra. I love a minimizer. I randomly bought this and thought I'd try it. Seriously...I absolutely love it. I was a bra merchandiser for a VERY large company for years, so I have bought and tried on hundreds of bras. This bra holds, gives amazing shape and is so comfy. The straps are wide so they won't fall down. The band is tight but comfy. The wite doesn't poke. The fabric is soft and stretchy. The unlined cups lift and give you great shape. If you are thinking about it, do it. You won't be sorry!

Comfortable and supportive. Didn't last as long as some of the other colors.
Super comfortable and supportive. Color and design were cute. Only issue is the wire broke through after a few months. Have bought many others from this same seller and had better luck with how long they lasted. I would buy again because of comfort if it goes on sale. Green and light blue one were also comfortable but long lasting. Nude colored one digs in under bust and doesn't have as much softness around wires.
