Extech 39272 Pocket Fold up Thermometer with Adjustable Probe

Estoy muy satisfecho con el producto es una herramienta muy práctica se los recomiendo tiene más de una función para medir temperatura de verduras frutas y más...

I do survey work on HVAC systems that are having troubles. I used a Cooper Industries digital thermometer for years. Still have it. This guy is nice because it updates rapidly, and you can easily tell when it has reached equilibrium with the measured fluid.The folding feature is nice as the device turns off when you fold in the probe. Saves on batteries! Also, when sticking this guy into a flex duct or a flex connector in rigid duct, leaving is half unfolded, allows you to let the unit hang, so you don't have to be holding it all the time.Some reviewers complained that it did not come to equilibrium quickly enough. Well, to get that kind of response time requires that you have virtually no mass in the probe - which means you are stuck with the end of a thermocouple wire. Great for measuring free air or a pot of water. But if you have to stick the probe into a flex duct or flex duct connector, or a Pete's Plug in piping, then you're going to have to have a sturdy probe. This one does come to equilibrium quickly, so I find those complaints without merit.I don't give 5's casually. This is a good product.

I use this for tracking water temperature in the lake.It is easy to read and reliable.This is the second of these devices I have purchased. The first one lasted 3-4 years before the temperature reading became unreliable. It will not last forever but is one of the few devices on the market that will accurately monitor lake water temperature and the annualized cost is OK.

If you are looking for a device that alerts you when a temperature falls outside of a given range, keep looking.Other than my 100% regret making this purchase, I regret more that I waited longer than 30 days to try this out and now I can't return it.1) 24 hours after I removed the plastic thing that activates the battery, the low battery indicator turned on. Really? The included battery is only good for a single day?2) The unit is not intuitive at all. You will never be able to program it without the included booklet.3) I bought this product to alert me if the freezer quits working, and after programming, it did sound an alarm after I pulled the probe from the freezer- once. It alarms one time, for up to 1 minute, and then it is forever silent. This "feature" is documented in the instructions, however was not on the item listing when I bought it. So if the freezer quits while you are at work, you'll never know. What is the point of this alarm feature? If I could spend 24 hours a day next to my freezer, I could just look at the light to tell whether or not it is on.If the item description on the listing gave any indication that this unit only alarms once I would have never bought it. At least now you have been warned.

Does what it is designed to do and appears to be accurate. The display is larger than I expected and clearly readable. There does not seem to be a way to turn off the beep that it emits when a button is pressed.

This is my second one (accidentally threw the other one away). I did an accuracy test -- put the needle in some boiling water and it was 210. So two degrees off. I only use it for cooking so 2 degrees is not a big deal. Great product.

I installed it in my work truck and it is very accurate. Wish it used standard batteries.

Great, just what I needed, waterproof and with a long cable
