Questions & Answers

Would this work as a food thermometer?

Food is unaffected since its temperature would be 220 degrees F, but other areas of the body could benefit from it. Removing the plastic sheath, along with its all metal backings, also makes it suitable to attach a roast fork.

Can I use it I use for cooking?

This is suitable for use with an automotive air flow vent and a plastic sleeve that must be inserted into the vent to avoid a food-contact accident like last week's fire.

There are references to blue in between 40 and 50 of a blue bottle. No blue markings are visible on the image. In your opinion, what should be the shade ksed blue in the 40 to 50 range?

We have a bunch of FJC thermometers on hand, and all had a blue component from 40 mm - 75mm. The temperature at which we go home is 50 F. Excluding the other sellers, I know every inventory. Your letter is very kind and thank you.

Does what it says it would
5/5

Having it turned on was very helpful in proving that I was in fact an air conditioning wussy and confirming the air conditioning in my car was blowing too much. The next day I went to the mechanic, but they found I was off on fluids. While they inserted dye into the system, they were unable to detect leaks immediately. Now that my thermometer confirms that my air conditioner is blowing at a proper temperature, I can keep an eye on it in case it starts to rise again and need to remove it so they can take a look to find out what has leaked. A blue wedge between the 40 and 50 marks is used to make it easy to recognize an accurate temperature. Excellent results are expected.

SSSSLLLLLWWWWWW! This thing is awesome
3/5

Even though it seems to measure accurate, it has to be one of the slowest temperatures I have ever owned because of its measurements. For a reading the old-fashioned style glass thermometer with the red bulb on the bottom must be used twice, both times waiting longer. is hard to get out without making it steep. For about ten minutes at first, the material cooled down, before heating it up two more times to check for air temperature effects on the outside of the vehicle. A quick, safe read of your air temperature would not be right for you. The data may be used within a room or a sample room such that it is comparable to the temperature of a similar setting. An appliance such as a dishwasher may work without a probe, though in the case of food.

Very cold with minimum degrees of absorption
3/5

There is a reading of at least 10 degrees below its temperature. Comparing different ways to measure infrared warmth from digital, analog, and laser devices. You can use this thermometer within an air conditioning duct as long as it fits in a standard probe. You have most likely met your goal by putting 10 degrees in each of the scales automatically.

You can get a great probe thermometer for an heating or air conditioning unit if you have one already
5/5

One is placed in a vent of a truck's AC so that I can monitor the cooling (and indirectly the pressure at work). Can't find a better use for such a small bit of equipment.

With this pen-style thermometer, you get great value
5/5

But, I believe this measurement is accurate, even though I have a digital air conditioner temperature for it. My purchase was quite well made, and I found it well worth the low price. I used it to monitor the cooling efficiency of my air conditioning supply vent and the temperature of my refrigerator or freezer. Temperature readouts of all metal shafts. The holding mechanism on the back of the blue plastic pouch is also available. This unit can be attached to the ceiling by clips.

Simply what I needed
5/5

If I wanted to know what the AC input temp on my cars was, I bought this. An accurate thermometer with this functionality could be more helpful than an infrared one. The instrument works just fine despite being tested against several more thermometers.

Even a moderate accuracy with Old School is adequate
4/5

At 2 degrees C. While not fully secured, it can sometimes flip on its face as it comes down on its face. Make sure you read it for at least three or four minutes just to sort it out. It's okay, but when the time comes, I'll probably opt for a digital device.
