Pretty accurate, too bad it can't show temp in F

I got two of these, mainly for the humidity reading which compared to my other meters is off by 1% and 5% @ 40-50% humidity.  It'd be nice if the temp display could be changed to F but that's not too important for me.  I just wanted something cheap that was within 5-10% accurate.

Others have already covered this product's features well.  Overall, I love the product but I will add that the temperature display should be considered incorrect unless the unit is calibrated by you.  My product was more than 50 degrees C cooler than the display indicates.  There is an easily accessible calibration port on the front, though it is very sensitive.  Ideally, you will have access to a high temperature probe to test the tip at its normal operating temperature.  I used a Fluke 80TK Thermocouple Module with a multimeter.  These are rather expensive.  Perhaps there are cheaper options like test materials that melt at a known temp.

I bought this directly from SRA soldering since I was ordering a number of their other products.

Awesome.  Would give it 5 stars, if there was a way to set a max temp somehow.

This is fun and easy to read, but I'm not convinced on the accuracy of the temp readings!

Well, it does measure temperature as advertised. But the display is none too bright, and really needs a bright ambient light to be clearly visible.

Good but doesn't give me my current temp in the house

Easy to read, and the functions work as advertised. The wrist band is sturdy and mostly the watch is commfortable to wear, although a bit heavy. Unfortunately, the thermistor reading is  ~1.5 F too high and I couldn't find a way to calibrate it. Also the temperature reading is useless while being worn (follows body temperature), which sort of misses the point of having a temperature readout on your wrist. I had a Casio watch with a thermistor years ago where the sensor was exposed on the surface so that it gave a reasonably accurate reading while being worn, so I know it could be better.

This thermometer works well and looks fine. The only flaw is that the control buttons are on the back. This means that you have to lean it forward to read what the buttons are if you use it on a desktop, or actually remove it from the wall to even access the buttons if wall mounted. The buttons themselves are quite small and in a recessed portion of the back of the unit. I took one star off for that. Having to run a wire outside is a bit of a pain and kind of limiting. I have yet to find a good spot to keep the thermometer which is close enough to where I can get an outdoor temperature reading in the shade. For that reason I'll probably end up buying a wireless outdoor thermometer and just use this one for indoor temp and humidity. I didn't take a star off for the wire because that is the nature of the item. I did take another star off because the product description implies that it reads temperature and humidity indoors and out. It does not. It only reads indoor humidity.

I love the min-max temp function that automatically resets every day. The only thing this is missing is a barometer. Wish they would've squeezed that in.

Works well, but would be better if it had a swivel readout, as the location of the socket on my car has the readout pointing downward. Also, would be good if the function of the wire sticking out of the unit is explained. i assume it is a temperature sensor.

Edit: temperature seemed high, so I checked it against other known good thermometers. It reads about 8F hith, unacceptable. I'll try to return it.

I bought two of these thermometers to use in mini-refrigerator/freezers (dormitory units). They are convenient to use and easy to read. When sitting beside each other they always gave the same reading. The problem with them is they read 10 degrees low over the actual range of 30 degrees to 72 degrees. So when the actual temperature was 40 degrees, they read 30 degrees. The variance from the actual temperature was constant over that range, but deviated to as much as 14 degrees low when the actual temperature was 4 degrees. If you have a way to calibrate them for accuracy, they can be useful. Otherwise, you will be taking a chance that the indicated temperature may not be correct.

I have the La Crosse Technology 302-604S Silver Indoor Digital Thermometer and both numbers for the temperature and humidity match each other, which confirms it is accurate. I really like it that I can see the minimum and maximum temperatures so I know how cold or warm it's been for my little 1 week old.  I also don't like it that the humidity number is larger than the temperature number.  What's up with that????  It wasn't worth taking off one point, however.

Note that I purchased an AcuRite 00613A1 from Amazon about 2 years ago.  I never opened it and just opened it last week.  Unfortunately the one from two years ago (opened new) is reading humidity numbers off by about 4-5 points, and the temperature is also about 2-3 temperatures lower.  I'm unsure why that would be the case, but just proves that this thing may eventually become inaccurate (hence why I purchased the La Crosse one too, to compare).

Accurate and easy to use, however, you have to either know what the temp is in celsius, or have an easy to use conversion app. For my use, monitoring the temp and humidity in incubators and brooders for quail chicks, that's not a serious issue. I know what the temp range they need to be in in both F and C, and can tell if it's out of range without having to convert the numbers anymore.

This is a very attractive thermometer/hygrometer/clock.  The only problem (and it's a major one) is that it is rarely accurate in terms of temperature.  I have it mounted in the shade as suggested but nevertheless, during the day it usually reads about 10 degrees hotter than it actually is during the summer.  It is closer to accurate when the sun is down, but still not right.  I'll be curious to see if it is more accurate in winter.  Also, the hygrometer seems to be accurate most of the time, but on a few occasions it has read zero humidity on fairly humid days.

I find it humorous that the manufacturer has the word "precision" in their name.

The clock works great, the inside and outside temperatures have been great and (I assume) accurate.  It did take 2-3 hours after installing batteries before it set itself to the right time.

The weather display on the middle is very fuzzy at guess what the weather is.  It does not communicate or receive the forecast from any external source, it simply decides whether the weather is "improving", "staying the same", or "getting worse", and displays the corresponding sunny, cloudy, raining icon.  I'm in Arizona, and it's funny how often it has the clouds or even raining clouds when there is rarely a cloud in the sky.  I supposed I should have researched or guessed that it probably isn't an accurate weather forecast pulled from some radio or online source.

Once you get used to the setting criteria, it is very affordable yet does its job very well

And I think it is quite accurate as well regarding Temperature and humidity sensing.

One cool feature is a swap button on the back side which instantly makes conversion from Centigrade to Fahrenheit and vice-versa.

Recently checked this thermometer against a calibrated standard; at 32F it was spot on, between there and 160F it was off 0.4 - 0.7 degrees and the error was linear.  Not bad for a $16 thermometer, highly recommended
