Can this be used to check for household germs?

"Germs" is a term that includes many different organisms. Bacteria, fungi, viruses, and protozoa often all get lumped into this category. There are good (beneficial) organisms as well as dangerous ones. Unfortunately, the beneficial and harmful ones do not follow any specific pattern of fluorescing or not fluorescing under UV light. I've had lots of fun looking at dust under blacklight. You would be amazed at how much of it lights up-- including bits of paper.

Germs are microscopic, but it might reveal colonies of bacteria. I guess many organic fluids, such as those our cats secretly secret around the house, are entirely evident with this light, especially when you also use the tinted googles.

I imagine it would kill a buttload of germs, If regular vinegar at 5% kills 80% of germs then it stands to reason that 20% would kill 320% percent of germs. Any germ this did not kill I would be proud to have. In using this for house cleaning be aware that it is real acid and may etch the surface of some things. If it removes the rust from old tractor parts it is pretty strong. You might consider asking on some cleaning advice forum before using this on a fancy fridge or stone counters.

Yes, but since it's an outside temp rather than internal, don't expect it to match normal readings. I've been thinking of using this with, say, sleeping grandchildren who may have a fever. My first step will be to run some trials to establish what this thermometer reads when things are normal. Then I will have the baseline for determining fever. The only issue is that it is a laser beam, so when using it on any person who is awake, be sure the laser doesn't hit them in the eye!

I don't know, not sure if there's a way to tell now. I've used it for the past few months and have had any major health problems. If you know how to test let me know.

It can be used at home. I use it for camping to sanitize dishes. It doesn't have the drawbacks of using bleach to sanitize. Especially when young cub and boy scouts are using it under supervision.

No, it is just to check purity or cleanliness level. It doesn't tell anything else.

My daughter's class grew household bacteria samples. They used the provided swabs, moistened with sterile water.

Haven't used for home canning but I don't see why it wouldn't work. You have to be careful not to dip the tip too far into liquid (past the black cover) because the device is not waterproof. You also need to buy some calibration fluid to get accurate results. I bought ph4 and ph7 calibration packets to calibrate. They cost about a dollar a piece. This is not a bad tester considering the price. I have been using mine for a saltwater aquarium for a few months and it has worked well.

I hope so, my doctor's office uses them. One of the reasons I bought this for home use. It gives consistent readings. It also gives accurate readings (sigh).

Unfortunately, not, as I have tried. It's best for just getting rid of germs.

Yes this should work fine since you have sufficient time window to obtain reading. I have used it to get reading of water temperature coming out of faucet and soups etc. Also used it for correct water temperature for yeast.

You would need a lot of saliva and urine TDS readings would be very high. The product is intended to test H2o

I would assume so, but best to test it at home under your watch just to be safe!

I don't think I'd rely on it for pasteurization, as it measures the temp at the tip -- not along the entire length of the probe.I'd be worried about just getting a "spot" temperature -- unless you are absolutely sure that your entire tank has been mixed to a perfectly even temperature.

yes, not so sure about the accuracy as compared with thermometers used in taking fever readings. Just be careful with the infrared light/dot, what i know is the light could be harmful to eyes.

I guess you could use it for food, but I wouldn't. It's a cutting mat for materials and while it is self-healing, I wouldn't count on it for keeping out bacteria.

Hi. If you mean like cracks in the wall(s) or something like that, maybe. I haven't tested in those areas yet; but, it might work. But if you were wanting to detect mold growth or find out the humidity levels, that device won't do it. It only takes temperature from a fixed distance (see chart or if you own one, it's on the right side of the device). Hope this helps!
