🌡️ EXTECH Instruments Digit Thermometer: Accurate Temperature Measurement for All Applications Review

Great product that provides all the important information including alarms and a large easy to read display. I have several and I really like them. I'm only taking off one star because the battery life could have been a little longer. They need to be changed every few months.

I purchased this for my home in Florida to maximize my humidity monitoring abilities compared to other units I have. display min./max. Values and dew point combined with the brand name was promising. However, my bad experience was similar to another review here. The device reads 10-15% less than the other 3 devices I own, all of which are within 5%. No problem I thought, I'll take the calibration screw to adjust and everything will be fine. The screw was inoperable, which did not affect the…

I live in São Paulo, Brazil and need a third thermometer/hygrometer to monitor the temperature and humidity in my apartment. The hygrometer doesn't match the other two, the Der Difference is more than 10 percentage points. The so-called "humidity calibration adjustment" does not work. Then, two weeks later, the temperature gauge suddenly jumped to a steady 80 degrees Celsius (the same as 176 degrees Fahrenheit). I tried the "temperature calibration setting" which is also fake: it doesn't work…

I've had it for 2 1/2 years. At first it seemed to compare well with the other two humidity sensors I had. Humidity readings have decreased over time and are now approximately 15% lower than other sensors. As other reviewers have reported, the humidity calibration screw doesn't work, unlike the temperature calibration screw, which works fine. So I'm going to support another reviewer's suggestion that you should check the calibration work when purchasing. Screw right away instead of waiting…

The dew point gauge was the reason I bought this product. It works well, has long battery life and is accurate. The dew point indicates how much moisture I can safely add in winter without condensation forming on the windows. This also indicates the efficiency of the air conditioning in summer. "Delta T" (temperature change, intake air temperature minus cold air temperature) indicates how much heat the air conditioning system is dissipating. Because the air conditioner also removes moisture…
