TempPro TempAir PLUS TP62B Wireless Indoor Outdoor Thermometer & Hygrometer — 500ft Range, High/Low

My second one. First unit purchased was checked against a lab standard, was within +/-2 deg. F within temp. band of interest; relative humidity reading close enough. Plus, supports two slave temp. gauges. Really good for $20.

Works great. Love that the light doesn’t stay on all the time as we have it in our bedroom and would be bright at night. It’s easy to quickly turn it on when we need it and it goes off quickly.

5 stars> I've had this 2 0c station for about two years now and it still runs perfectly. Had to put new batteries in it a few times but that is it. Easy to set up and easy to use and simple, clear display gives you instant outside temp and humidity from nearly any where in your home.The Florida weather can be hard on things like this. But we have not had a problem at all.

Works great. Very accurate.We have extreme cold and warm summers in Cedar City Ut.

I first bought the ThermoPro TP50 indoor thermometer about 6 or 7 years ago. It worked so well that I soon bought the TP60 indoor outdoor thermometer with the remote sensor. Later I bought a second TP60. When I get a new thermometer, I always check the accuracy against others that I have. All of these have shown a temperature of less than 1 degree of others that I trust, and humidity has been pretty close to each other. These have all been set on tabletops using the kickstand.I decided I wanted another ThermoPro to hang on the wall. For where I wanted it, I also wanted a little larger screen. I bought the ThermoPro TP62. It’s 3.2 wide x 3.9 high with a 3.3-inch screen compared to the others at 2.6 wide x 3.1 high with a 2.7-inch screen. Also, the TP62 has the control buttons on the front rather than the back which is good for a wall mount. If you are going to place the thermometer in a place where you want to read it in low light, the TP62 has a sensor on the top center that when touched lights the screen for a few seconds.Each of the ThermoPro thermometers I have are accurate and I think are going to last a long time. The batteries last 1 to 2 years, sometimes longer. I haven’t tried putting a sensor at the maximum range of 500 feet, but at 50 feet they read through multiple walls without fail. In normal room lighting they are all easy to read, but in low light or a dark room the TP62 screen will light up.

I was surprised how good this unit is after a month's use. The only feature I'm not sure of yet and which could affect future review is battery life, but so far it is much better than the Oregon Science unit it has replaced in that:• the sensor transmits easily from outside one end of the house to the room completely at the other end and through metal siding; the last unit could not do that• While initially I had the sensor indoors right next to the receiving unit and the indoor and outdoor temps differed by a few degrees, I found this was from handling the sensor. The difference went away with time. Outdoors, the sensor sends a temperature which is within one half degree of my expensive and accurate Davis Vantage View weather station. The two devices are in someone different places in the yard, one in sun the other not, but on cloudy, calm days when the readings should be the same, they are• The contrast on the display makes it very easy to read. The display unit is relatively small but the digits completely fill the whole screen and are readable from across the room• The backlight works very well with a tap in the center top of the display• The max-min feature is not explained well in the manual but works this way: you reset the max-min by holding that button for 5 seconds, then there is another button that gives you the choice of showing the max-min temps from the last time you did a reset or the max-min temps within 24 hours of that reset. So if you reset at 11:58 PM and use the 24 hour choice it gives you the max-min since the last 11:58 PM and then starts all over for the next 11:58 PM. It counts 24 hours internally. There is no clock. If you choose the “all time” setting instead of 24 hours, the max-min never resets and you will see the max-min since the last time you reset which could have been a month ago. The unit only operates in one of the max-min modes at a time. If you set it to "all time" you cannot display the 24 hour value.• The only”con” I would register is that there is no beep or other indication that the max-min reset has been successful. You can check to see if the max-min are both the current temp when you do the reset, but a beep would be nice.
