Hi David! My name is Mike, and I work at Bel- Art/H- Instrumental Group B SP Scienceware is a software company that specializes in science. br>First, a quick answer: "no," you cannot use this thermometer to measure the temperature of people. The temperature reading will only be accurate for a short period of time.br>The old-fashioned thermometer will not work. Time thermometers like the ones we used as kids were made to take the temperature and stay there until the doctor or nurse held it up to read it.

The thermometer's line divisions are another reason you can't use it on people - There is a line every 2 degrees on this one. Every DEGREE will have five or ten lines on a regular people thermometer! You couldn't get a 98 with our thermometer. Only 96, 98, or 100 degrees according to the reading. Because it was not designed to deliver the accuracy required in oral thermometers, this thermometer misses the critical measurement points. br>To read the temperature, you don't need to be a fortune teller; all you need is the appropriate thermometer. br>If this does not answer your question, please contact me at [email protected]...

The thermometer read 45 degrees on a 31 degree morning. The thermometer read 75 degrees in my 63-degree house. Every pocket thermometer listed on Amazon appears to use the same technology, and I don't want to keep looking for one that works, so I'm going to look on eBay for a vintage mercury pocket thermometer. In 1709, Daniel Farenheit invented the alcohol thermometer, and in 1714, he invented the mercury thermometer. It would seem that accurate thermometers would be a piece of cake three hundred years later.
If you want to read this correctly, you'll have to act quickly because the temperature is rising. As soon as you take this out of your mouth, it begins to dissolve. This isn't the kind where you shake it to cool it down before putting it in your mouth, like the old mercury ones. It's known as About this product, I spoke with the manufacturer. He claimed that the newer models do not contain mercury, which could break the glass if dropped. This isn't made of glass or mercury, and it can't even maintain a consistent temperature. I won't buy another one, and I wouldn't recommend it to anyone. Maybe I'm old fashioned, but I'd prefer the old ones with mercury in them. I swear I'm not going to throw it away. Of course, digital versions, similar to those found in a doctor's office, are now available, but they are prohibitively expensive for those on a fixed income. Change isn't always as exciting as it appears; ) I guess I just prefer the traditional ones, which, in my opinion, do not need to be updated.
My first attempt to use it resulted in it breaking. It was delivered the next day. The glass is extremely fragile, and the tip popped right off as I was removing it from the case!.
This is a nice, calibrated, easy-to-read thermometer with a temperature range that's relevant for household use, despite the fact that mine came in purple. For example, I bought a Rubbermaid refrigerator thermometer and used it to check the temperature of the refrigerator (the Rubbermaid was 2 degrees off). br>br>Because the thermometer reads temperature quickly and the blue liquid against the white scale (with black numbering) is easy to read, you can get an accurate temperature reading quickly. br>br>Even though the actual thermometer is glass (so this isn't a good item for small children! ), ) The thermometer is packaged in a sealed bubble wrap package with a vacuum formed plastic carrier. After you've opened both of these disposable items, the actual thermometer is still protected by its plastic sheath, which is attached to the top end of the thermometer so it doesn't fall off. The thermometer's plastic end piece is blue in the product picture, but mine arrived purple, with a loop to connect to a cord or hang up with. br>br>In terms of thermometers, it isn't particularly unique or "trickish. " It's basic and functional, but most importantly, it's calibrated, so you can be sure the temperature displayed is accurate.
It was purchased so that I could keep track of the temperature in my new refrigerator. When the Thermometer is on the shelf, I can read it. The thermometer appears to be well-made and durable - for a thermometer made of glass br>br>On the Thermometer, the numbers and other markings are sharp and complete; for example, a number has no gaps in its lines or ragged edges. The case appears to be made of both plastic and metal. It's nicely constructed. br>br>The scale appeals to me - The temperature ranges from 30 to 120 degrees Fahrenheit, which is ideal for non-cooking purposes around the house. br>br>The Thermometer is a round device that rolls across flat surfaces. The Thermometer measures 5 5/8 inches in length. br>br>My only suggestion for improvement is something to keep it from rolling on a flat surface, and that could be adjusted to turn the Thermometer at an angle that allows you to see the temperature reading the best. I'd buy it again. br>br>.
Thermometer arrived with a 20-degree offset in the scale due to an air bubble in the fluid. A simple fix is to tie a string to the top and swing it hard to remove the air bubble using centrifugal force. After a little tweaking, it's perfect. When compared to an IR thermometer, it is extremely accurate. There are no batteries to replace, nothing to break, and it comes with a nice plastic holder. It's a great room thermometer if you hang it on a tea cup hook. The scale goes up to 220 degrees Fahrenheit, so it can be hung from a car mirror to show how hot it gets in the summer sun. I'm going to buy a few more, one for each floor of the building and one for each vehicle.
I bought this Fahrenheit thermometer as well as the dual Centigrade/Fahrenheit thermometer (ASIN B00551OH8A), which are both the same size and have the same temperature range (0 to 220 F or -). (between 10 and 110 degrees Celsius). The scale labels on this thermometer are larger and easier to read because it only has a Fahrenheit scale. I prefer this model to the dual reading model because converting from F to C is so simple. The scale font is 3/16 inch tall and "bold," as opposed to the dual scale model's 2/16 inch "fine font. " There is a noticeable difference in readability on the surface. br>br>It appears that the blue versus red fluid of other thermometers is only a color difference, and there is no difference in readability. A sliding pocket clip is attached to the thermometer's aluminum protective sleeve. A lanyard ring (not included) is attached to the cap. The thermometer in its protective case measures 6 3/8 inches in length overall. It's 6 inches outside the protector; The scale measures 3 1/8 inches in diameter. The thick glass makes the thermometer more durable and less likely to break, and the white backing makes it easy to read. For a small, pocket thermometer, a 2 degree F accuracy is acceptable. br>br>In the field, I use the thermometer to measure the temperature of streams and lakes, and its protective sleeve and small size make it very convenient. As a take-out item, I would suggest it. As long as the temperature range and accuracy are sufficient for your needs, you can use a standard thermometer.
