iProven Triple Mode Thermometer TMT-215 Review

iProven Triple Mode Thermometer TMT-215  is intended to measure the body temperature of humans. The ear measuring function can be used for babies who are a minimum of six months old. The forehead function can be used for all ages. It measures the body temperature based on heat radiating from the eardrum or from the forehead. Although this thermometer has undergone extensive clinical tests and is considered safe and highly accurate, it is intended for non- professional home use only.

The object mode shows you the temperature of your baby’s bottle and meal, or even their room and bed, in a second.

How should I clean the device?

Regularly clean the thermometer probe with a damp cloth, moistened slightly with water. You can clean the lens of the probe with a cotton swab. If you want to disinfect the sensor probe, use a disinfecting wipe or a cotton ball dampened with a disinfectant. You can prevent the sensor from getting stained by ensuring the ear canals are clean. Caution: This thermometer is not waterproof! Do not immerse or expose it to water or any other liquid other than using a slightly damp cloth.
