Mercury-Free, Glass, Oral Thermometer C/F

Muy Buenos

This mercury-free glass oral thermometer is a reliable and safe choice for everyday health checks. It provides quick and precise readings in both Celsius and Fahrenheit. The glass design feels sturdy and easy to clean, and I love that it’s mercury-free—safer for the whole family. Plus, the price is very reasonable for such quality. Highly recommend!

It may be accurate, but its impossible to read with any degree of accuracy. 98.6 is labels, but not marked (the 98 is over 98 degrees and then there are 5 minor lines and the next major line is where 99 would be). It's also VERY SLOW to shake down, and I grew up with the old style mercury thermometers so I know how they should work. I have a digital thermometer that I bought years back specifically for tracking fertility and I've been pleased with it's accuracy (lines up with this thermometer but gives measurements to the hundredths of a degree), so I'm going back to using that.

Works really well. Unfortunately my daughter dropped it, breaking the glass. Bought the same one again & am still very happy with it. Accurate & more reliable than flakey digital equivalents to me. For the uninitiated, know that these kinds of thermometers require that you give them a rather aggressive/vigorous “wrist snap” to reset the temperature.

Are you a fan of the accuracy of the old mercury and glass thermometers? This one, while containing no mercury, will please you. It take a bit longer to give a reading (around 3 minutes for oral use) but gives a more accurate reading than many digital thermometers. It also comes in a nice plastic case for travel. The downside: this is a glass thermometer. While if does have a case, the case will not protect the thermometer from impacts. We owned this thermometer 2 days before it was accidentally knocked off a table and shattered on the floor. It is fairly fragile and I wouldn't recommend it for homes with children, rambunctious animals or klutzy adults (like me).

This resets with a quick snap FLICK of the wrist--not a waving like it's hot motion. Like in any TV show or movie made before the 2000s. One side will show a long blue line (ignore this) and the other view will show the actual temperature reading. This is due to the properties of glass being glass--it's glass, so you can see through it. It diffracts light and color. Like looking at a straw in a glass of water. It takes three ACTUAL minutes...set a timer. It really doesn't move at all for the first minute-and-a-half. So make sure you wait three real minutes. I guess it's *slightly* more complicated than screwing in a lightbulb...but at least you don't have to deal with dead thermometer batteries while also being sick.

UPDATE at end: Very accurate! I am shy of the digital thermometers and feel I can sterilize the glass thermometer much more reliably. I’ve been using this thermometer daily since March - I have two and occasionally swap and also benchmark them against each other - same reading every time. These are hard to shake down, apparently the media does not weigh as much as mercury and takes much more effort to shake down. So much so I created a paracord rig to “spin” mine down as I think I was developing shoulder issues. If someone has a more brilliant shake down method, I’m open to suggestions. UPDATE: I dropped one of mine so I ordered two replacements - these now come with a tool for shaking them down - also in reading the manual, manufacturer suggests shake down to 36 C however I have been “spinning” mine down into the tip.

Rating of zero. The product makes great claims, however upon shaking the thermometer and multiple email communications with the seller the thermometer still does not work. You put it in your mouth and it has a zero reading! Because the company is third-party, you have to get their approval (which they waste your time and then zero response) or file a separate claim with Amazon all taking me over two hours thus far… I give up! Very disappointed in Amazon and their choice of this third-party vendor and their lack of protocol/process for returns.
