EXTECH Devices Digit Thermometer

Extremely Satisfied – Would Recommend to a Friend
I just installed a whole house dehumidification system in my home and needed 2 hygrometers for the main floor and the basement. I wanted to buy an accurate unit with a large print digital display. Thus far, the temperature tracks right on target with my expensive furnace thermostat. I have nothing to check the accuracy of the humidity readings, but assuming they are fairly accurate, I was able to adjust my Aprilaire humidity setting to keep the humidity levels at ~ 50% in both locations. The unit has a fold up stand on the back of it so I did not choose to wall mount them. I placed one of them on a book case shelf in my great room and one on my office desk in the basement. I also like the mount of the sensor on the outside of the unit which produces a more accurate humidity reading. I have used the Extech units for 1 month, but I am extremely satisfied with their performance to-date. They are more expensive than many others, but always believe that most of the time you get what you pay for by spending a little more money. In this case, I am protecting my entire home against humidity damage and was willing to pay more for a quality product. As usual, Amazon’s pricing was better than the competition for this product. I can’t testify that there wasn’t a better price out there, but the price was good and Amazon’s excellent shipping policy for Prime customers made the decision easy.

Build Quality Questionable ==> Review Updated
Out of the box the unit would not power up (or perhaps just the display simply would not power up). After replacing the battery, which I thought must be DOA, I discovered that the display powered up after pressure was applied near the battery compartment. Upon further troubleshooting, the sweet (dead) spot turned out to be an area on the left size of the bezel just below where the probe is mounted. Applying very slight pressure at this point shut the unit down. (Again, it could be just the display losing power.) I could get the unit to stay on, but the slightest touch to the left bezel again shut it down.I don’t object to overpriced Chinese-made goods–it’s today’s reality–I do object, though, to sloppy quality assurance. (Neither the shipping box nor the unit packaging showed any signs of distress, by the way.)Thanks to Amazon’s no-hassle return policy, this unit is being sent back. Since I’m desperate for a hygo-thermometer that is easy to read, I ordered a replacement unit. I’ll give it another try.Update 2015-03-08: The replacement unit from Amazon powered up without issue. In comparing the temperature reading to three other hygro-thermometers, it was within 1 degree. The humidity reading is within 4 percent of my other units, which is within tolerance. The unit responds very quickly to temperature changes. After three weeks in my wine cabinet, I am satisfied with the performance.Further, I’m impressed that a rep from Extech Instruments offered to assist. (See comment to original post.) The value of good customer support cannot be overstated. I’ve changed my rating from 1 to 4. Keeping me from rating a 5: Value. At a Chinese labor rate of about $2.50/hour, I expect a better price.

Llevo usándolo varios meses para monitorear la temperatura y humedad debido a una alergia y cumple perfectamente con su función.

This is a very good instrument displaying exactly what is relevant: Relative humidity, temperature and dewpoint. The dewpoint calculated from the other two is very useful to know but most other instruments show the time instead and who wants that on an instrument like this? The alarm functions and the max high and low recordings are useful as well. Designed by a respected instrument manufacturer by engineers with a vision.I lost my old one and had to find an exact match since nothing else could serve my needs any better.

Instructions for the product are not available in English nor in French. Only in “Chinese” Not really useful.
