Pros && Cons

IProvén DMT-489 is cost-effective one with accurate measurement and humanized design , although it’s not perfect. But considering the price to performance ratio , it’s a very good choice.

  • Accurate and quick. Same with INV-EF100.
  • Large screen and easy to read.
  • Memory function. Remember the last 20 temperature, it’s enough to used.
  • Easily operate and read.
  • Safety, it’s a digital infrared thermomenter and not contain any mercury.
  • Dual model, take both forehead and ear temperature.
  • High Fever Alarm can’t be turn off when a fever is detected.
  • No guidance on temperatures , IRT6520 and many of others thermometers can show you tips to help you understand the reading (color coded Green-Yellow-Red or different beeps).
  • Need careful to protect the probe and keep it far away from water.


IProvén DMT-489 used For any age, because it is safety, no danger and do not cause pain, but for newborn, choose braun IRT6520 will be better. Several tips need to make notice when measure temprature:

  • Ensure keep contact with forehead when measure
  • Do not measure temperature after sports or taking a bath.
  • Don’t clean the probe with alcohol but use dry cloth.
  • Difference ±0.2˚C /±0.4˚F is normal
  • The IProvén DMT-489 sensor is extremely sensitive. Any oil or dirt will prevent an accurate measurement.
  • The ear mode is not suitable for children under 6 months
  • It’s not intended to serve as a continuous monitoring device.
  • It’s not waterproof.
  • It can’t replace medical supervision.
  • Do not twist the thermometer or the temperature sensor
  • Remove the batteries if the thermometer will not be used for longer than three months
  • If environmental condition changed, wait at least 30 minutes
  • Keep it out of children’s reach.


IProvén DMT-489 take infrared detection technology and through a large number of clinical testing accuracy is higher , compare with other forehead thermometers , It’s accurate but a little difficult to use in my opinion. The accuracy is ±0.2˚C /±0.4˚F. it’s really worth at the price. As mentioned. If used for newborn braun IRT6520 will be better because of Age Precision® Technology for age adjustable fever guidance.   Body temperatures between 36.0˚C and <37.6˚C or 96.8˚F and <99.7˚F are considered normal body temperatures.
