Im looking for good indoor thermometers. They can be the ones that read indoor and outdoor temp, indoor/outdoor/humidty. whatever. My main goal is that I want to know what thermometer I can buy that is trustworthy and will always read a true accurate temperature. The temperature is the most important thing. I want one that is 100% accurate. or 99%

I have lots of different thermometers through out the house some digital, (all acurite brand from walmrt, two different models.) some with mercury or whatever the old ones have in them. some that have the metal wire wrapped in a circle that expand and contract to give you a temp. I just want to know accurately what the temperature is.

The ones I have now all give different readings. I grouped about six thermometers all together in the same room the other day and every single one gave me a different reading. well some were reading the same and some from the low temp to hi temp differed 2 degrees. thats a big difference when it comes to knowing the actual temperature.

Also how accurate are Termostats. I have a Hunter model 42999B http://www.hunterfan.com/product_detail.aspx?id=7414

How accurate is this thing?

i want to know when im looking at it, that it is the right temp and not off a freaking degree.

I have an old springfield indoor/outdoor themometer in my kitchen. I believe the indoor is reading pretty accurate but the outdoor, not so much. Indoor temps are within about 2' of my livingroom where my duct comes up from the stove. I would expect it to be a bit cooler out there. For some reason, the outdoor side of the thermometer shot up to about 98'-100' about 2 weeks ago and has been there ever since. As I type this, it's 25' outside and the thermometer still reads about 100'. So what do ya'll think? Time for a new one? :roll: :D

Try these guys, a bit more expensive, but they make them for scientific use and come with calibrated sheets, etc..

If you're only looking for reading indoor temps. just look for a liquid in glass thermometer made by Springfield or Taylor etc. Mercury isn't that common now so most thermometers now have alcohol/spirits (red stuff) in them. If it's silver then it's a mercury one. If you really want to get serious about indoor/outdoor conditions then I would recommend Davis weather stations. http://www.davisnet.com/weather/index.asp I have several of these stations including one in Colorado that I download data from and send to the local Colorado NWS forcast office. I've been operating these since 2003 and find them just as accurate as the official NWS equipment.
Here is a photo of one of my stations. The device on the galvanized pole at left (with black top) is a Davis weather station (Vantage Pro). It is Solar powered with battery and data is transmitted by wireless to a Console inside the house. The anemometer on the tall mast came with the station as well. The Console in the house shows inside temp., humidity, barometric pressure as well as data from outside. The weather shelter (white box on stand in photo) is for other equipment not associated with the Davis weather station.
These stations aren't cheap but if you really want to know what's happening with the weather they're just as good as official very expensive weather sensing equipment IMO. There's lots more info on the Davis website.
BTW most thermometers/electronic temperature sensors have +/- 1°F accuracy.

I have the Vantage Pro II wireless system. It's MINT! That's how I know how many inches-per-hour the rain is coming down. Records every event going back for 24 years: wind speed & direction, indoor/outdoor temp & humidity rainfall totals for day, month, year, 20 year .... has graphs for each. Pretty neat. Even has a ticker for the forecast! 8-)

Has all kinds of extras available that I didn't need - - like leaf wetness gauges, & solar sensors .... it can be hooked up to irrigation systems for farming, & water only as much as needed. There's also a computer hookup so you can send data to your local TV station, or post it online. Too much extra dough for me. The unit cost about $700 if I remember right. :shock:

Yeah, the VPII is nice. I don't have all the fancy stuff on mine, just the basics, temp. wind, rain, barometer and humidity.
BTW, my station in Colorado at my Mom's recorded a -4°F yesterday morning :fear: . That's very common there though.
