Question: does it run on battery? what type?
Document: It is less than three inches square. Looks like the picture but is much smalller. Also it needs a battery.
it was compact, easy to see the big numbers. I like that it's in English and not metric. only takes a triple A battery
I keep this located on my reloading bench. Has been flawless for over a year. I bought a second for an ammo storage closet. Also flawless. Long battery life.
Great for temperature and humidity readings. Does require a battery, but haven't had to replace it since I bought it several months ago. There have been some complaints about the accuracy of the humidity reading, although it is within 6% to 7% of the reading on my dehumidifier, which is in the same room.
I use it in a basement to decide when to flip on a Dehumidifier. The only thing I was surprised about, as the original photo looks like a flat, wall mountable device... It isn't. It has a battery compartment that sticks out at the bottom so it can stand. Not a problem, but look elsewhere if you wanted to wall mount.
Bought two of them. One for upstairs and one for down. However, I put them on the piano side by side and they were off 2 degrees on the temperature. Hydrometer was the same on both. So far so good. I think if I would buy another one, I get an analog type, just because of the batteries. Gave them 4 star because of the temperature differences.
At first I thought this was great, just stuck the battery in (not included!) and saw a large, uncluttered display. Problem is, temperature is wrong. The thermometer has been saying my bedroom has been in the 75 degree range for a week or so. This is just not true. Today I installed my air conditioner. After cooling the room to 68, the thermometer started reading 76. One star! Return please!
I bought this because the thermostat and HVAC at work broke and I needed to prove to the electrician that it was only 62 degrees in my work area. They have since installed a new digital thermostat and this one registers within .3 of that one so I believe it is very accurate. Love that it uses a regular AAA battery. And it is nearly instant read when you move it to a new location. Very tiny and cute too.
Today is 2/3/14. When I tried to order it last night for the living rm , description said something to the effect of "usually ships in one to two months." Often there is a way to contact seller w/questions, which I have done recently on Amazon, but I couldn't find that type of link. I settled for another, less "attractive,"more expensive item that is on its way. I have several plastic ones in different rms and basement. Very disappointed.
This is a pretty simple product and seems to do an excellent job and is very accurate. I have one for the bedroom and living room, as we live in GA humidity is a big problem for us in the summer spring and summer, and we have to run humidifiers in the winter, so this helps us keep the house just right. As we have found out too much humidity can cause mold. This was nothing fancy, price we right and does an excellent job, I would recommend this product.
Answer: yes
