AcuRite 00888A3 Indoor/Outdoor Digital Thermometer,Silver,Small

Nice thermometer. Works well if used properly. The wire attached to the unit needs as much of it as possible outside in order to registerr properly. It is best to have the thermometer sitting on the inside window sill and most of the wire with the temperature probe outside. If too much wire is inside, the temperature will register higher or lower than it actually is, dependington on the seasons.. Set the unit to F for the American unit of measure. It register outside temperature, and with e a push of a button inside too. Good value for a durable device. We had one for years until a storm ripped the siding off the house and cut the cord. This purchase is a replacement.

Although advertised and marketed for home use, I re-engineered this as an inside-outside car thermometer. The installation didn't require cutting into the dash, or a funky looking 12v cigarette lighter hook-up (although, one can tap into the fuse-box). The readout size is good for old eyes. How to mount? Some of the others use velcro, so I stuck two small strips on the back, leaving it clear for the AAA battery changes. You should also leave a few extra inches of wire play for battery changes, too. Anyways, voila with the velcro stick. No, it's not uber-solid, but under normal street driving conditions it's not going to fall off the dash. I also lengthened the wire for the outside temp sensor (another 15" to reach an area in front of the radiator--add more if you want the option of experimenting with the sensor location). It's very fine strand wire, so be careful in stripping the insulation off. (I'd have to guess at the gauge.) Twist and solder wires for best connection, insulate with shrink tube and then seal with silicon or silicon grease. (You can figure this out, right?) Installation time was roughly an hour, because I'm old and particular about things. Add another hour for the soldering and relocating of the outside sensor (for the same reason). I'm sure others could whip through this job more quickly. [Note: Handle the sensor with care. Enough said.] This may sound like a lot of work, but again, nothing compared to cutting out your dashboard and leaving a gaping hole if you're not happy with it. Sensor reading for inside the car and outside is great. Accuracy of the two sensors was tested inside the house and both were within a .1-.2* of each other. Close enough for me. Although brand B*ll was smaller, and almost the same price depending on the unit, I'm happier with my AcuRite conversion. This thermometer design may not work for every car interior, but it looks great on my wife's gray dashboard (2004 Ford Focus). It's rounded on the edges and goes well with the vent shapes. I don't expect it to last forever, but if I get a few years out of it, good enough for $12.

I use the Chaney Instrument as an outside thermometer for my car. Snaked the outside lead through the engine compartment and mounted the sensor (it just sticks on) to the grill in front of the radiator. It has proved accurate (comparing it with posted temps along side the road) as long as the car is moving. When still, it picks up the radiator's heat, so the "max" part of the min/max function has limited usefulness in my application although that is not the fault of the unit, but where it needs to be mounted on the car. It switches easily from inside to outside temperature and, given the previous comment, the min/max function is useful. Why not 5 stars? The light on the thermometer, which is triggered by a push button, is pretty dim. It is difficult to read the thermometer a night with the light button pushed it is so dim. The manual cautions not to push the button too often or battery life with suffer...it is hard to fathom that such a puny light would draw much power. But time will tell about that. For the price, it is a good buy.

This is my 2nd purchase of this same thermometer. The first lasted years and then I tried others to my disappointment. Others were too complex, failed, short battery life and inaccurate. I have reordered and reinstalled this this one again. I installed it in my car with the wired sensor out under the front hood and under the front bumper. The wire is easily long enough. It is accurate, simple, and lasts a long time.

I like this because of its simplicity. The fact that, because it is not wireless, it has a small "probe" that hangs outside with doublestick tape makes it easy to stick on places you would not want to put a screw for the wireless unit. I have just ordered a second one to test the temperatures in my new refrigerator/freezer. It has a maximum/minimum feature I will use too. The face is big enough to read, although, because it is black on gray, I often need a flashlight. The built in light is nearly useless. It seems to be accurate.

My previous different indoor / outdoor gadget failed me twice. I like a simple machine. This one is proving easy to set up and operate with minimal fuss. Its wire doesn't mind windows and screens.

Over two (2) years ago I purchased this AcuRite Chaney Instruments Indoor/Outdoor digital thermometer on Amazon. It has been used to monitor the temperature in a hard-to-reach crawl space underneath our home. It has operated accurately and flawlessly since its date of purchase - without the need to change its original (single AAA) battery. The lengthy (10-foot) wire connecting the temperature probe to the monitor is a great feature which allows tremendous flexibility regarding its possible applications. Would I buy this product again? Yes - absolutely! If you go to the manufacturer's website, you can easily search the model number of this product and access a PDF copy of the User's Manual.

Nice big display. Reads in Fahrenheit or Celsius. Thin enough to sit on window ledge.

The description/images seems to imply that the sensor probe can be used in aquarium, and my need was for pool temperature and after short period of time, the sensor no longer provided accurate readings. After reading the actual instructions, it does say that sensor is "water-resistant" should be only immersed for max 30 seconds as prolonged use will cause sensor to malfunction.

Good price. Used for temp for under cottage in winter months
