FAQ ABOUT TP63B
Hi. Just got it and I am charging the sensor. Sensor and unit are in the same space as you can see. At first there was a wide variance in the data, as some reviews have commented on. But in leaving them alone for over an hour the data between devices stabilized and is very close, as you can see. Plenty good enough for my needs. Size is relatively compact, but text is large, both a plus for me. I own a similar different brand without a backlight, which is the main reason I purchased this. But this is much easier to read, even without the backlight, than my other brand. So far I'm happy. My only concern is the rechargeable sensor, honestly I would prefer batteries. But who knows it may hold a charge a long time. I will try to modify this post if something bothers me in the reasonable future. Otherwise all is good.
As it said works like it should.
Really nice and easy to read!
as listed, works great
Very reasonable price. I bought this to have a monitor for outside temp from inside after wife accidentally broke the thermometer hanger on the porch. I was impressed enough with the performance of the first unit, I bought two more of the sensor units. The display alternates the 'Out' reading on the top of the display between three possible units. If you just have one, it stays on that reading, but if you have two, the display will cycle between all three, leaving the third sensor (if not there) reading blank lines. I found it annoying enough to buy a third one to fill that spot in the display cycle with a separate garage reading. These devices are each about a degree apart in the same location and the humidity reading as much as 4% different in same location, but they are close enough for my use purposes. The display is very easy to read from several feet away with bad eyes, the screen has a light button at the bottom that is very useful at night, and I am over a week on the first charge of the outdoor sensor.
