## Questions & Answers

**Q: Can you use it in your mouth?**
A: Hi!  My name is Mike at Bel-Art/H-B Instrument & SP Scienceware.
Unfortunately, no.  We do not sell any thermometers suitable for taking body temperatures.  These types of thermometers are designed completely different.  First, the temperature range is usually only 10 degrees, from 96° to 106°, so you can get accurate readings between the critical temperatures.  Secondly, These old-time, “shake-down”  thermometers we grew up with were actually designed to go to the temperature, and STAY at that temperature until the doctor or nurse held it up to read it.  That makes sense because in the short time from the patient’s mouth to the doctor’s reading, the temperature could have started going back down to room temperature.  
This may not seem like a big deal, but remember 98.6 degrees in normal and 99 degrees is a low fever.  Just 0.4 degrees made the difference between sick or not sick.  So it was important that the liquid inside the thermometer didn’t move until the temperature was read.  
How did they manage to design a thermometer with this capability?  Easy.  At the bottom of each thermometer, just above the bulb of liquid, the small capillary inside that the liquid travels up has a ‘trap’, a little ‘S’ turn designed into it!  YES, you are right in thinking that it took some pretty skilled glasswork to make these, but that is the way it is done.  This is just like a real small version of your sink’s ‘S’-trap below the drain.  The dimensions of that small capillary varied depending on the length of the thermometer and the temperature range of the thermometer.  These types of thermometers are called “Maximum Registering” because they stay at the highest temperature they reached until they could be accurately read and the temperature recorded.
So finally, to get the liquid back down into the bulb, yup, you guessed it, the nurse or the doctor had to ‘shake it down’, getting the liquid passed the ‘s’ bend and back to the bulb.
I hope this answered your question, but if not, please email me at michael.grzelak@spindustries.com…

    Good pocket thermometer
  

*by R***K on Reviewed in the United States on November 24, 2022*

The Amazon photo does not show the correct thermometer.  I purchased it using the model number B60570-2100 in the description.  This is a 20-120F range pocket thermometer with about a 6-5/8" aluminum tube that it stores inside of.  Unscrewing the tube to remove the thermometer is slightly annoying.  I've bought two of these now and both are right on at 32F in an ice bath.  These work very well for checking water temps while fishing which is the sole purpose I bought them.  The 1 degree increments are great and easy to read.  Getting a temp is quick, usually within 20 seconds.  It's amazing how inaccurate most pocket thermometers are that I've purchased over the years.  Finally for the first time in my life I have an accurate thermometer.  Great buy at around $26.I recently ordered a third thermometer B60570-2100.  That specific manufacturer number is supposed to be a glass thermometer that you unscrew and remove from a closed metal case.  The first two I bought were correct and the third one I just reordered is a glass thermometer in an aluminum duplex case.  So they still have the wrong main photo for this product and now has some thermometers that are labeled wrong on the packaging.  Unless they now decided to use the model number on a different product without updating their website.I was looking at the manufacturer website again and they have both the B60570-1600 and B60750-2100 listed as "closed metal case".  Neither of these is listed under "aluminum duplex case".  They are getting them mixed up when they are selling them which I why I received two of one and one of the other when ordering model B60570-2100.  The closed metal case is what I wanted and received the duplex case this time around.  Pretty frustrating.I purchased a fourth thermometer listed as B60570-1600 listed as closed metal case.  It was exactly the same as the first two I bought.  This one is off by one degree in an ice bath, reads 33F degrees.  Still much closer than all the other brands of inexpensive pocket thermometers I've bought in the past.

    Garbage Thermometers
  

*by G***M on Reviewed in the United States on February 25, 2021*

Thermometers arrived with bubbles in the liquid, rendering them completely useless right out of the package.

    Photos are not accurate, but description is.
  

*by J***E on Reviewed in the United States on August 19, 2023*

Other reviewers have stated that they didn't receive either what was in the description or what was in the photo.  What I received was model B60570-2100:  a pocket thermometer, registering 20 to 120F, in an aluminum duplex case.  That matches the description and it is exactly what I wanted. It is the same as the second photo in this listing, except for the scale.  In case Amazon changes the photos, I have uploaded a photo of the one that I received.One reviewer stated, "Unscrewing the tube to remove the thermometer is slightly annoying."  I don't know if he meant that the extra step was annoying or that the screw threads were difficult to engage.  In the first case, the thermometer is glass, so needs some type of cover to protect it when not in use, as it is a POCKET thermometer and meant to be at least somewhat rugged.  In the second case, the cover is made of aluminum and aluminum screw threads nearly always need a little lubrication to protect against seizing.  I put a little silicone lube on mine, but I'm sure any type of lubrication that is safe for aluminum would work.The thermometer works well and is accurate, but if I had one complaint it would be that the thermometer rotates freely inside the metal guard and oftentimes needs to be rotated to view the scale and numbers.  Touching the thermometer delays the reading and adds body heat.  I think that the thermometer should probably have some adhesive to hold it in place inside the metal guard so as to be able to take readings as quickly as possible to avoid errors.
