Electronic Thermometer

My long-time electronic thermometer broke, so I bought a new one.
The built-in battery seems to have worn out, not only because of infection prevention measures, but also because my elderly family members have more opportunities to take their temperatures regularly.
Without time to do any preliminary research, I went to the sales floor of a local drugstore and was surprised to find several electronic thermometers available and surprisingly inexpensive despite their high functionality.

I remember that in the past, most thermometers did not have replaceable batteries to prevent infants from accidentally ingesting button batteries, but now they sell thermometers with replaceable batteries. I guess they have devised a way to prevent easy removal of the battery.
Some were waterproof and washable, which seems to be in high demand in this day and age, and some had an attached case that could be easily cleaned with alcohol.

After much deliberation, I chose the Terumo thermometer we had been using previously and purchased a thermometer with a sound pressure about twice as loud and easy to hear at the end of a temperature test. It can predict temperature in about 20 seconds and measure temperature as speedily as a temperature check at a hospital.

Terumo's electronic thermometers Terumo's registered trademark

The Terumo logo in the image is naturally a registered trademark (Japanese Registration No. 6191923 Protective No. 01), but a further search on J-PlatPat revealed more than 250 patents, utility models, and designs for Terumo’s electronic thermometers.

By the way, Terumo thermometers have had a 100-year history. What is the 100th anniversary commemorative thermometer sold last year! If you are interested, check the following site♪ (Cacao)
